Essential Pipeline Maintenance Services Explained

Pipelines are built to move critical products safely and efficiently, often over long distances and through places where failure is not an option. But no pipeline is “install and forget.” Over time, internal buildup, corrosion, pressure cycles, and ground movement all take their toll.

That’s where essential pipeline maintenance comes in. When inspection, cleaning, testing, and repair are planned and coordinated, operators can keep systems safe, compliant, and productive for years beyond their original design expectations.

This guide explains the core services every operator should understand—and how APS helps turn those services into a practical maintenance program.

Why Pipeline Maintenance Matters

Pipelines serve communities, industries, and critical infrastructure. When they fail, the consequences can be serious. Essential pipeline maintenance is about preventing those failures before they happen.

Safety and Environmental Protection

The most important reason to maintain pipelines is safety. A small defect left unaddressed can grow into a leak or rupture that threatens people, water sources, and land. Regular inspection and maintenance allow operators to identify corrosion, deformation, and coating failures in time to act.

For lines carrying oil, gas, chemicals, or wastewater, the stakes are even higher. Proactive maintenance reduces the likelihood of releases and gives operators confidence that they are meeting their responsibilities to the environment and the communities they serve.

Operational Efficiency and Cost Control

Maintenance also has a direct impact on day-to-day performance. Internal buildup, scale, wax, and debris all restrict flow and increase friction. Pumps and compressors work harder, energy costs rise, and throughput drops.

By keeping pipelines clean and in good condition, operators maintain design capacity and reduce operating stress on equipment. 

Planned maintenance is always less expensive than emergency repairs and unplanned downtime.

Asset Longevity and Compliance

Every pipeline has an expected life, but that life is not fixed. Essential maintenance services—inspection, cleaning, testing, and internal protection—can extend the useful life of existing assets and delay costly replacements.

Regulation and internal integrity programs increasingly require operators to document how they manage pipeline threats over time. 

Maintenance isn’t just about what happens in the field today; it’s also about having a clear record of inspections, tests, and repairs to support audits and risk assessments tomorrow.

Core Pillars of Essential Pipeline Maintenance

Effective pipeline maintenance rests on a few core pillars. Each service plays a distinct role, and together they form the backbone of a strong integrity program.

Inspection and Condition Assessment

Inspection is the foundation. Without accurate information about the condition of your lines, it’s impossible to make good maintenance decisions.

Inline inspection, or intelligent pigging, uses sensor-equipped devices that travel inside the pipeline to detect metal loss, dents, and other anomalies. 

These tools can identify internal and external corrosion, pitting, and deformation along the entire route of the line.

In addition to inline inspection, operators may use visual walkthroughs, external NDE, or local ultrasonic checks where pigging is not practical.

At APS, Pipeline Inspection / Pipeline Condition Analysis turns inspection results into clear, usable information. Our team doesn’t simply pass along data; we interpret what it means for your pipeline’s integrity, identify high-priority features, and help you understand where maintenance focus will have the greatest impact.

Pipeline Cleaning and Pigging

Cleaning is one of the most overlooked, yet essential, pipeline maintenance services. Over time, product residues, scale, biofilm, and debris accumulate inside pipelines. This buildup can reduce capacity, create under-deposit corrosion, and interfere with inspection tools.

Conventional pigging uses mechanical devices to sweep the interior of the line, pushing out solids and restoring a smoother bore. This not only improves flow but also makes subsequent inspections far more effective.

For water and force mains, APS offers Ice Pigging™, an advanced cleaning method that uses an ice slurry to scour internal surfaces without aggressive mechanical contact. 

Ice pigging can remove deposits and biofilms in a controlled way, often with less water and downtime than traditional approaches.

Our Pipeline Cleaning services are tailored to product type, line condition, and maintenance goals. We design cleaning programs that fit your operations and integrate seamlessly with inspection and testing activities.

Pressure Testing and Verification

Inspection tells you what defects exist. Pressure testing proves the system can withstand defined loads without failure. Both have a place in essential pipeline maintenance.

Hydrostatic testing involves filling a pipeline with water and pressurizing it to a specified level, typically above normal operating pressure. This confirms that the line can hold pressure and helps validate repairs, tie-ins, or changes in service.

In situations where water is undesirable—such as cold climates, moisture-sensitive systems, or smaller station lines—nitrogen can be used instead. 

Nitrogen pressure testing uses dry, inert gas to verify leak tightness and strength while avoiding the need for drying and water disposal.

APS has extensive experience with hydrostatic testing and nitrogen testing, integrating these services into pre-commissioning projects and ongoing maintenance programs.

Corrosion Control and Internal Protection

Corrosion remains one of the leading causes of pipeline failure. Cleaning and inspection identify where corrosion is occurring. Protective measures help slow it down.

Internally, contaminants and stagnant areas can accelerate metal loss. After cleaning and defect repair, internal pipe coating can be applied to create a protective barrier between the steel and the transported product.

APS combines cleaning, inspection results, and internal coating strategies to support life extension for aging pipelines. By targeting coating to the right places and conditions, operators can reduce corrosion rates and stretch the value of existing infrastructure.

Repair, Rehabilitation, and Life Extension

Maintenance doesn’t stop with finding defects; it continues through effective repair and rehabilitation.

Inspection and pressure test results guide where to dig, what to replace, and how to reinforce vulnerable segments. Instead of replacing entire lines, operators can focus on high-risk locations, perform targeted repairs, and then protect the remaining sections with internal coating or other mitigation measures.

APS supports this process through our condition analysis work and our ability to tie inspection outcomes to practical repair and rehabilitation plans that fit your operating and budget constraints.

Data, Planning, and Integrity Management

Every inspection, cleaning, and test generates valuable data. When captured and organized, that data becomes the backbone of risk-based maintenance planning.

Tracking which segments have been cleaned, coated, tested, or repaired—along with their defect history—allows operators to identify trends and adjust maintenance frequency accordingly. It also supports regulatory reporting and internal integrity management requirements.

APS brings a systematic perspective to maintenance planning. We help operators use their existing data, and the results of our services, to structure a program that is truly preventive rather than reactive.

Preventive vs Reactive Pipeline Maintenance

There are two ways to deal with pipeline problems: respond when they appear, or work to prevent them from developing in the first place.

The Cost of Waiting for a Failure

Reactive maintenance often starts with an alarm, a leak report, or an unplanned shutdown. At that point, the options narrow. Emergency repairs are typically more expensive, more disruptive, and more visible to regulators and stakeholders.

Beyond the direct repair costs, unplanned outages can impact customers, contract commitments, and facility operations. 

In many cases, a failure also triggers more frequent inspections and reporting requirements going forward.

Building a Preventive Maintenance Cycle

Preventive pipeline maintenance is built around cycles of inspection, cleaning, testing, and repair carried out on a schedule informed by risk. Pipelines in higher-consequence areas or with more aggressive service may need more frequent attention. Lower-risk lines may require less frequent, but still consistent, maintenance.

When APS helps design a maintenance cycle, we look at age, product, construction details, environmental exposure, and inspection history. 

The goal is to find a cadence that keeps risk at an acceptable level without creating unnecessary downtime.

Risk-Based and Condition-Based Approaches

Risk-based maintenance focuses resources where the potential consequences of failure are highest or where the likelihood of problems is greatest. 

Condition-based maintenance uses actual inspection and testing results to determine when interventions are needed.

Inline inspection data, pressure test results, and coating condition reports all feed into these approaches. APS supports both strategies by providing services and insights that give operators a realistic picture of pipeline condition and risk.

Essential Pipeline Maintenance Services from APS

While “pipeline maintenance” can mean many things, APS focuses on a connected set of services that work together to protect your assets.

Pipeline Inspection and Condition Analysis

Our Pipeline Inspection / Pipeline Condition Analysis services help you understand what is happening inside your pipelines. From planning inline inspection runs to interpreting results, we ensure the data you receive is accurate, relevant, and directly tied to maintenance decisions.

We prioritize clarity in reporting, so your team can move from findings to field action without delays.

Cleaning, Pigging, and Ice Pigging™

APS’s Pipeline Cleaning and Ice Pigging™ services restore capacity and prepare pipelines for inspection and coating. Regular cleaning runs can become a core component of routine maintenance, especially for crude, refined product, and water systems.

By controlling internal buildup and creating a clean surface, cleaning services also improve the performance of pressure testing and internal coating applications.

Pre-Commissioning, Hydrostatic Testing, and Nitrogen Testing

For new lines or systems returning to service after major work, Pipeline Pre-Commissioning ensures that cleaning, drying, and testing are carried out in a logical, efficient sequence.

Our hydrostatic and nitrogen pressure testing capabilities confirm that pipelines can safely hold pressure and are ready for operation. These services can also be used as part of periodic maintenance or revalidation programs.

Internal Pipe Coating and Life Extension

For pipelines with corrosion history or limited replacement options, internal protection can be a critical maintenance tool. APS applies internal pipe coating after proper cleaning and preparation, helping operators reduce corrosion rates and extend the life of existing infrastructure.

Mapping, Turnkey, and Consulting Support

Understanding the physical route and environment of a pipeline is just as important as understanding its internal condition. APS’s mapping services provide insight into alignments, elevations, and external hazards.

Our turnkey and T&M consulting support helps operators design maintenance programs that stay aligned with budgets, regulations, and long-term asset strategies.

Signs Your Pipeline Network Needs Maintenance Attention

Not every pipeline issue is obvious, but certain signs suggest that essential maintenance may be overdue.

Operational changes—such as increased pressure drops, reduced throughput, or higher energy consumption—can indicate internal buildup or developing restrictions.

Assets with limited records, aging coatings, or known history of corrosion require closer attention. And when regulations change, or when similar assets in your sector experience failures, it’s often a signal to review your own maintenance plans.

APS can help assess where your current program stands and identify which lines should be prioritized for inspection, cleaning, or testing.

Getting Started with a Pipeline Maintenance Plan

Developing an effective maintenance plan doesn’t have to be complicated. It starts with understanding what you have, where it is, and how it has been operating.

From there, you can rank pipelines based on age, service, location, and consequence of failure. Lines that carry higher risk or have the least information typically move to the top of the list.

Once priorities are set, APS can help you design a program that integrates inspection, Pipeline Cleaning, Ice Pigging™, Pipeline Pre-Commissioning, hydrostatic and nitrogen testing, internal coating, and mapping into a coherent strategy that fits your operations.

Frequently Asked Questions About Pipeline Maintenance

What is considered essential pipeline maintenance?

Essential pipeline maintenance includes inspection, cleaning, pressure testing, corrosion control, and repair or rehabilitation activities that keep pipelines safe, efficient, and compliant. These services work together to manage corrosion, debris, and structural integrity over the life of the asset.

How often should pipelines be inspected and cleaned?

The right interval depends on factors such as product type, age, environment, and regulatory requirements. High-risk lines may need more frequent inspection and cleaning than lower-risk ones. Inline inspection and condition analysis results are often used to refine maintenance intervals over time.

What maintenance services reduce internal corrosion in pipelines?

Cleaning to remove deposits, followed by appropriate internal protection, is key. Removing scale, wax, and biofilm reduces under-deposit corrosion, while internal pipe coating can provide a barrier between the steel and the transported product.

What is the role of pigging in pipeline maintenance?

Pigging is central to pipeline cleaning and inspection. Cleaning pigs remove debris and buildup, while smart pigs collect data on wall thickness, dents, and other defects. Techniques like Ice Pigging™ provide specialized cleaning options for water and force mains.

How do hydrostatic and nitrogen testing fit into pipeline maintenance?

Hydrostatic and nitrogen testing verify that a pipeline can safely hold pressure and is leak-tight. They are often used after repairs, tie-ins, or major projects, and they can be part of periodic revalidation programs to confirm ongoing strength.

Can an older pipeline still benefit from maintenance instead of replacement?

Yes. Many older pipelines can continue to operate safely when they are cleaned, inspected, repaired, and internally coated as needed. Maintenance extends life and allows operators to plan replacements on their own schedule rather than in response to an emergency.

How can American Pipeline Solutions help with my pipeline maintenance plan?

APS provides integrated services that cover inspection, cleaning, Ice Pigging™, pre-commissioning, pressure testing, internal coating, mapping, and condition analysis. We help you prioritize assets, design maintenance programs, and execute field activities that improve safety, reliability, and long-term performance.

Challenging Pipeline Inspection

Pipelines are built to move energy and water safely, often in places that are hard to reach and even harder to see. Over time, many of these lines end up in a category operators know well: challenging or “unpiggable” pipelines. 

These are lines that cannot be inspected with conventional tools or standard smart pigging runs—yet they still carry critical fluids through cities, river crossings, plants, and sensitive environments.

At American Pipeline Solutions (APS), challenging pipeline inspection is not an exception. It is a core part of how we help operators protect assets, reduce risk, and meet regulatory expectations. 

This blog explores what makes a pipeline difficult to inspect, why traditional approaches fall short, and how APS combines cleaning, smart pigging, Ice Pigging™, inspection, and consulting to turn “unpiggable” lines into inspectable assets.

What Makes a Pipeline “Challenging” or “Unpiggable”?

Not every pipeline was designed with inspection in mind. Some were installed decades ago under roads and rivers. Others were built as compact station piping with tight elbows and complex manifolds. Over time, operating conditions change, tie-ins are added, and drawings go missing.

A pipeline becomes “challenging” when one or more of these factors make standard in-line inspection (ILI) or pigging difficult, risky, or impossible.

Geometric and Design Challenges

Geometry is one of the biggest reasons a line is labeled unpiggable. Tight bends, short-radius elbows, mitred bends, and back-to-back fittings can stall or damage conventional pigs. 

Multi-diameter segments—such as transitions between two nominal sizes—or lines with wyes and tees add more complexity.

Non-metallic or heavily lined pipe sections, like HDPE or cement-lined segments, can also limit which technologies can be used. In many older systems, the pipeline was simply never equipped with proper launchers and receivers, so there is no obvious way to introduce or retrieve an inspection tool.

Operational and Product Constraints

Even when the geometry looks manageable on paper, operations can work against you. Low or unstable flow may not provide enough energy to push a conventional pig. 

Some systems cannot be shut down or depressurized, so inspection has to happen with the line live.

High temperatures, slurries, or aggressive fluids can damage tools or distort signals. In other cases, operators cannot change the product, batch, or flow profile enough to meet the requirements of standard ILI tools.

Access and Location Limitations

Many of the most challenging pipelines are buried deep, cross rivers or highways, run through plants, or sit under busy intersections and airports. Installing a launcher or receiver in these locations can be difficult, time-consuming, or disruptive.

Even if the pipeline can be accessed, above-ground space may be cramped, with limited clearance or nearby structures, making safe pigging operations more complex.

Age, Condition, and Legacy Design

Aging infrastructure adds another layer of difficulty. Vintage welding techniques, undocumented tie-ins, older coating systems, and unknown changes along the route can make inspection planning more uncertain. 

Build-up of scale, wax, tuberculation, or other deposits may narrow the bore and increase the risk of a pig becoming stuck.

Data and Interpretation Challenges

Finally, the challenge is not just moving an inspection tool through the line—it is making sense of what comes back. Challenging pipelines often produce complex data sets: mixed wall thicknesses, unusual welds, and localized defects in unexpected places. 

Turning that data into clear, defensible decisions requires experience, judgment, and the right analytical tools.

Why Conventional Inspection Methods Often Fall Short?

Standard in-line inspection tools are designed for reasonably straight, reasonably clean pipelines with consistent diameters, adequate flow, and purpose-built launchers and receivers.

In challenging lines, these assumptions break down. Pigs may stall, bypass sections of pipe, or stop collecting usable data if they experience severe turbulence, heavy debris, or excessive friction. If the line cannot be cleaned properly, deposits can mask corrosion or create false signals.

External methods alone—such as limited exposure digs, spot ultrasonic testing, or walking surveys—can help but often cannot provide a complete picture, especially for long buried sections. Hydrostatic testing can confirm that a line holds pressure, but it does not tell you where metal loss, cracking, or other local threats may be hiding.

For these reasons, difficult-to-inspect pipelines require a different approach: one that combines cleaning, modified operations, specialized tools, and thoughtful engineering.

Modern Solutions for Difficult-to-Inspect Pipelines

Challenging pipeline inspection is not about one magic device. It is about having a toolbox of technologies and services—and knowing how to apply them in the right order.

Specialized In-Line Inspection Tools

Today’s ILI tools are far more flexible than earlier generations. Low-flow and low-pressure tools can operate in lines that once seemed off-limits. Bi-directional and tethered tools make it possible to inspect lines without permanent launchers and receivers, moving in and out through a single access point.

For multi-diameter and station piping, flexible tools and small-diameter inspection devices can navigate tight geometries that conventional pigs cannot safely traverse.

Advanced Sensor Technologies

Inspection tools may carry Magnetic Flux Leakage (MFL) sensors, ultrasonic transducers, deformation sensors, or high-resolution cameras, depending on the threats being evaluated. MFL is ideal for detecting metal loss and corrosion, while ultrasonic tools can quantify wall thickness and characterize cracks and laminations.

Choosing the right technology—or combination of technologies—requires a clear understanding of pipeline materials, operating conditions, and the types of defects most likely to occur.

Cleaning and Preparation: The Hidden Challenge

Even the best inspection tool cannot perform well in a dirty or heavily obstructed pipeline. Cleaning is often the hidden challenge that dictates whether an inspection will succeed.

APS uses Pipeline Cleaning programs tailored to the line’s conditions, which may include conventional pigs to remove debris, as well as Ice Pigging™ for water and force mains where biofilm and tuberculation are a concern. These steps help restore internal diameter, reduce friction, and ensure that sensors have a clear path to detect real defects.

In pre-commissioning projects, Pipeline Pre-Commissioning services align cleaning, gauging, and initial inspection so operators start with reliable data from day one.

Temporary Modifications to Make Pipelines Piggable

Sometimes, a pipeline simply cannot be inspected without modest changes. Temporary launchers or receivers, bypass loops, or spool pieces may be installed to create safe access points. 

In other cases, minor operational changes—such as adjusting flow, pressure, or batching—can expand the window of opportunity for inspection.

APS supports operators through Turnkey / T&M / Consulting services, helping design these modifications, coordinate field activities, and balance inspection requirements with operational constraints.

Data Analytics and Integrity Engineering

Collecting data is only the beginning. Turning it into action requires structure.

APS uses Pipeline Inspection / Pipeline Condition Analysis services to evaluate inspection data, compare it to historical information when available, and identify where repairs, recoating, or pressure adjustments may be needed. 

This may be paired with mapping to better understand pipeline alignment, elevations, and high-risk features along the route.

The result is not just an inspection report, but a practical integrity plan that operators can implement.

Risk, Compliance, and Integrity Management

Challenging pipelines often run through high-consequence areas or support critical operations such as refineries, tank farms, industrial plants, or municipal water systems. Leaving these lines under-inspected can increase the likelihood and impact of failures.

Regulators and internal integrity programs increasingly expect operators to address difficult-to-inspect lines using a documented, risk-based approach. 

That may include demonstrating that the line has been cleaned, that an appropriate inspection method has been selected, and that results have been translated into a clear plan of action.

By combining inspection, testing, cleaning, and internal coating where appropriate, APS helps operators close gaps in their integrity programs and demonstrate due diligence for even the most complex assets.

How American Pipeline Solutions Tackles Challenging Pipeline Inspection

APS has built a reputation for tackling complex, high-stakes pipeline projects for oil, gas, water, and chemical systems. Our approach to challenging pipeline inspection is methodical and collaborative.

Starting with an Engineering Review

Every project begins with understanding why the line is considered challenging. APS reviews available alignment sheets, as-built drawings, operating envelopes, pigging history, and known trouble spots. Where information is missing, we work with operators to confirm what is known and what must be assumed.

This engineering review helps identify whether the main constraints are geometry, operations, access, legacy design, or some combination of all four.

Making the Pipeline Inspectable

Once the constraints are understood, APS designs a practical path forward. That may include staged cleaning, adding temporary access points, adjusting flow or pressure during inspection, or combining internal tools with external assessment techniques.

Our Pipeline Cleaning, Ice Pigging™, and Pipeline Pre-Commissioning services often play a central role in making a previously unpiggable line ready for inspection. 

When corrosion or damage is present, internal coating can be used after repairs and cleaning to extend the service life of the pipeline.

Selecting the Right Inspection Method

With the line prepared, APS helps operators select appropriate inspection methods: smart pigging, robotic or tethered tools, guided inspection techniques, or combinations that offer the best coverage.

Smart pigging tools are chosen based on the threats being evaluated—metal loss, deformation, cracking, or a mix. 

From Raw Data to an Integrity Plan

Inspection is only successful when it leads to clear decisions. APS’s Pipeline Inspection / Pipeline Condition Analysis services translate raw inspection data into dig sheets, repair priorities, and timelines.

Where beneficial, this is combined with mapping and historical information to build a more complete picture of pipeline behavior over time. 

Operators can then plan targeted repairs, make informed decisions about recoating or internal coating, and establish re-inspection intervals that match the actual condition of the line.

Example Scenarios of Challenging Pipeline Inspection

Every pipeline is different, but challenging lines often share recognizable patterns.

Small-Diameter Station Piping with Tight Bends

In station piping and metering facilities, small-diameter lines with short-radius elbows and numerous fittings can be especially difficult to inspect. There may be no launcher, and space is limited.

APS can design a cleaning and inspection sequence using small-diameter tools, temporary access, and careful flow management, turning a static risk into a documented, managed asset.

Aging Water or Force Main with Limited Access

Urban water and force mains often run under roads and developed areas with limited access points. Heavy deposits and tuberculation can further narrow the pipe.

Using Ice Pigging™ and cleaning services, APS can remove internal build-up, then apply appropriate inspection techniques and condition analysis to determine whether repairs, lining, or internal coating are required.

Multi-Diameter Pipeline with Flow Constraints

In some oil or gas lines, sections of differing diameters and long distances between access points create challenges. Flow conditions may be marginal for standard pigs.

APS can employ multi-diameter-capable pigs, staged cleaning runs, and carefully managed operating conditions to complete inspection runs. 

Combining ILI data with hydrotests, leak history, and mapping yields a robust view of fitness-for-service.

How Asset Owners Can Prepare for a Challenging Inspection?

Operators can do a great deal to set a challenging inspection project up for success. Gathering current and historical drawings, documenting operating limits, identifying locations where access is particularly limited, and clarifying shutdown constraints all help shorten the planning phase.

Engaging APS early allows our team to align consulting, cleaning, inspection, mapping, and coating strategies into a single, integrated plan rather than a series of separate tasks. This reduces overall cost, avoids rework, and delivers better data the first time.

Why Partner with American Pipeline Solutions?

Challenging pipelines demand more than standard tools—they require a partner with the experience, creativity, and discipline to work through constraints step by step.

American Pipeline Solutions combines Pipeline Inspection / Pipeline Condition Analysis, Pipeline Pre-Commissioning, Turnkey / T&M / Consulting, Pipeline Cleaning, Ice Pigging™, internal coating, and mapping into cohesive programs that make difficult lines inspectable and manageable.

Our focus is simple: help operators understand the true condition of their pipelines and act on that knowledge with confidence.

If you are facing a pipeline that others have called “unpiggable” or difficult to inspect, APS is ready to help you find a path forward.

Frequently Asked Questions About Challenging Pipeline Inspection

What is a “challenging” or “unpiggable” pipeline?

A challenging or “unpiggable” pipeline is one that cannot be inspected with standard inline inspection tools due to factors like tight bends, diameter changes, lack of launchers and receivers, low flow, or difficult operating conditions. These lines require customized inspection strategies and specialized tools.

Can all pipelines be made piggable?

Not every pipeline can be made piggable without modification, but many “unpiggable” lines can be inspected once the right cleaning program, temporary hardware, and inspection technology are put in place. APS focuses on making difficult pipelines inspectable where it is practical and cost-effective to do so.

What are the most common reasons pipelines are difficult to inspect?

Common reasons include complex geometry (tight bends, mitred elbows, tees), low or unstable flow, limited access or missing launchers and receivers, heavy internal deposits, older construction with unknown features, and constraints that prevent shutdowns or large modifications.

How do you inspect a pipeline with no launcher or receiver?

Options include installing temporary launchers/receivers, using bi-directional or tethered tools, or deploying robotic crawlers that can enter through existing access points. The best solution depends on pipeline layout, product, and operating constraints, which APS evaluates during the engineering review.

What inspection technologies are used for challenging pipelines?

Advanced inline inspection tools may use magnetic flux leakage (MFL), ultrasonic testing (UT), EMAT, deformation sensors, or cameras. For especially complex pipelines, robotic or tethered tools and external assessment methods may also be applied as part of a combined integrity strategy.

Why is challenging pipeline inspection important for integrity management?

Difficult-to-inspect pipelines often run through high-consequence areas or support critical operations. If they are not inspected properly, defects can go undetected, increasing the risk of leaks, failures, regulatory issues, and unplanned downtime. Challenging pipeline inspection helps operators understand and manage these risks.

How can American Pipeline Solutions help with my challenging pipeline?

APS starts by understanding why your pipeline is considered challenging, then designs a practical plan that may include cleaning, temporary modifications, and specialized inspection tools. The goal is to safely collect high-quality data and turn it into a clear integrity plan you can act on with confidence.

How to Remove Stuck Pigs in Pipelines Safely?

When a pipeline pig does not arrive at the receiver on time, operators are faced with a situation that can quickly turn from an inconvenience into a serious integrity and safety concern. 

In the context of pipeline pigging, a “stuck pig” is a pig that has stopped moving or slowed dramatically inside the line due to debris, geometry, or mechanical issues.

A stuck pig can restrict flow, increase backpressure, delay operations, and, in the worst case, contribute to overpressure or damage to the pipeline. 

Because of the stakes involved, stuck pig recovery must be approached in a structured, safety-first manner—not with improvised fixes.

This guide walks through common causes, typical recovery methods, and best practices for dealing with stuck pigs. It also explains when it is time to stop troubleshooting and bring in specialists like American Pipeline Solutions (APS) to support safe, effective recovery.

Safety First: Before You Try to Move a Stuck Pig

Removing a stuck pig is a high-risk activity. The pipeline is already in an abnormal operating state, and there is stored energy behind the pig in the form of pressurized gas or liquid. 

Every action taken must follow company procedures, applicable codes, and the pipeline’s design limits.

The most important safety rule is never to exceed the pipeline’s Maximum Allowable Operating Pressure (MAOP) or any test pressure limit defined for the system. 

Attempting to force a pig through a restriction by simply pumping harder can lead to pipe failure, equipment damage, or serious injury.

Ad-hoc tactics, such as uncontrolled pressure spikes, quickly opening or closing valves, or sending personnel into confined spaces, have no place in safe pigging operations. 

Before any recovery attempt, the section of pipeline must be properly isolated, valve positions verified, vent and relief paths confirmed, and everyone involved aligned on the recovery plan.

Why Pipeline Pigs Get Stuck?

Understanding why pigs get stuck is the first step in preventing future incidents and choosing an effective recovery method.

One of the most common reasons is debris and build-up inside the pipeline. 

Wax, scale, sand, black powder, construction debris, or foreign objects can accumulate ahead of the pig and form a plug that it cannot push through. If the line has not been pre-cleaned or has long intervals between pig runs, the risk of this kind of blockage increases.

Bore restrictions and geometry also play a major role. Unbarred tees, partially closed valves, sharp-radius bends, dents, buckles, and changes in diameter can create tight points that the pig simply cannot pass. Even a relatively small deformation may be enough to trap a pig that is a tight fit.

Incorrect pig design or sizing is another contributing factor. Pigs that are oversized and have very stiff cups or discs can create high friction and require more differential pressure than the system can safely deliver. 

On the other hand, pigs that are undersized may lose their seal, stall, or tilt in the bore. Poorly chosen bypass or venting designs can also reduce driving force or allow debris to accumulate around the pig.

Operational issues can make all of these problems worse. Low differential pressure, highly variable flow, or running a cleaning pig in a heavily contaminated line without staged cleaning can all increase the chance of a pig stopping in the line.

In nearly every case, better pigging planning, appropriate pig selection, and pre-cleaning strategies dramatically lower the odds of a stuck pig.

Step 1 – Confirm the Pig Is Actually Stuck

Not every delayed pig is truly stuck. Some pigs move more slowly than expected because of low driving pressure, heavy debris, or conservative flow rates. Before initiating recovery actions, it is critical to distinguish between a slow pig and a stuck pig.

Start by comparing actual pig run time to expected run time based on prior experience, pipeline length, and flow conditions. 

Review launcher and receiver records to ensure the pig was launched correctly and that the receiver is ready to accept it. Pig signallers, tracking tools, or time-stamped markers along the line can confirm the last known position and progress.

Pressure and flow trends provide valuable clues. A genuinely stuck pig often causes increasing backpressure upstream and reduced flow downstream, combined with little or no evidence of movement. If the pig appears to be making slow but consistent progress, it may be better to adjust operating conditions than to immediately switch to recovery mode.

Taking time to confirm status avoids unnecessary interventions that might turn a manageable situation into a more serious one.

Step 2 – Locate the Stuck Pig

Once it is clear that the pig is no longer moving, the next priority is to locate it accurately. Without knowing where the pig is, it is difficult to design a safe and effective recovery strategy.

Operators use a combination of methods. Pig signallers or tracking devices installed along the line provide location information at key points. Tracking logs can narrow the search to a specific line segment between two confirmed locations.

Changes in pressure or temperature between block valves, stations, or segments can also help estimate where the pig has stopped. 

In some cases, acoustic tools or geophones are used on above-ground sections to listen for faint vibrations or sounds associated with the pig.

For buried or subsea pipelines, more advanced methods may be required. Radioisotope tracers, electromagnetic tracking, or specialized line-of-sight tools can be deployed to pinpoint the pig’s position.

Accurate location data is essential. It informs whether simple measures like pressure cycling are likely to work, or whether more invasive approaches such as hot tapping or excavation will be required.

Step 3 – Start with Low-Risk Recovery Techniques

With the pig located and the pipeline stabilized, the next step is to use low-risk methods to encourage the pig to move. All of these techniques must be carried out within the pipeline’s pressure and operating limits.

Pressure Cycling and Flow Adjustment

The simplest approach is to adjust flow and differential pressure to see if the pig can be gently pushed past the restriction. This normally involves increasing driving pressure or flow within safe limits and monitoring for movement.

If increasing flow does not help, operators may use pressure cycling. In this method, pressure is gradually reduced and vented toward the launcher, allowing the pig and any compressed debris behind it to relax. 

After a controlled depressurization, the line is re-pressurized to drive the pig forward again. This cycle can be repeated multiple times. 

Sometimes this repeated expansion and contraction is enough to dislodge the pig or break up a plug of debris.

Reverse Flow (If the System Allows It)

In systems designed for bi-directional operation, one option is to reverse the flow direction. By reversing the propellant or product flow, the pig can be encouraged to move back toward the launcher or another access point, where it can be safely retrieved.

Reversing flow requires careful evaluation of pump or compressor capability, valve configurations, and downstream facilities. 

Not all pipelines can support bi-directional operation, and any change in flow direction must be planned to avoid overpressure or unintended flow into sensitive parts of the system.

Run a Foam Swab or Small Pig Behind It

If a pig has stalled because it has lost its seal or is no longer generating adequate driving force, running a line-size foam swab or a smaller, softer pig behind it can sometimes help. 

The secondary pig or swab can re-establish sealing contact, increase differential pressure across the stuck pig, and push it forward.

This method requires careful selection of swab size, density, and type. A swab that is too stiff, too large, or poorly matched to the line can worsen the blockage by adding more material to an already tight section.

Chemical or Thermal Assistance

In pipelines where wax, scale, or other deposits are the likely cause, thermal or chemical methods can be used to soften the obstruction. 

Hot water, gels, solvents, or other approved chemicals may be injected into the line ahead of or around the pig. As deposits soften or dissolve, the pig gains a better chance of moving.

Any chemical or thermal treatment must be compatible with the pipeline’s product, internal coatings, elastomers, and downstream facilities. 

Environmental regulations and disposal requirements must also be considered before deployment.

Step 4 – Advanced Stuck Pig Recovery Methods

If low-risk techniques do not restore pig movement, more advanced methods may be necessary. These steps should only be carried out under the direction of experienced engineers and field crews.

Rescue Pigs

A “rescue pig” is a secondary pig launched specifically to interact with a stuck pig. The rescue pig is often smaller or more flexible and is designed to bump, push, or straighten the stuck pig so it can pass a restriction.

While rescue pigs can be effective, they also carry risk. If not carefully designed and modeled, they can compact debris further, lodge behind the stuck pig, or create a double blockage. 

Detailed engineering review and a clear understanding of the pipeline’s condition and geometry are essential before attempting this option.

Hot Tapping and Localized Access

In some cases, the best way to free a stuck pig is to create a controlled access point near its location. This can be done by hot tapping the pipeline. 

A hot tap involves installing a fitting and valve on the live pipeline and then cutting into the pipe under pressure using specialized equipment.

Once a tap is installed near the pig, operators can inject chemicals, relieve local pressure, or create a vent or bleed point. This can reduce forces acting on the pig and allow it to be moved by pressure cycling or other means.

Hot tapping requires specialized tools, experienced crews, and rigorous permitting. It also introduces new features into the pipeline that must be considered in future integrity assessments.

Opening the Line at an Access Point

Where the pipeline design allows, it may be possible to isolate, depressurize, and open the line at an existing trap, valve site, or spool. With the line safely de-energized and opened, technicians can use mechanical retrieval tools, hooks, or grips to remove the pig and any accumulated debris.

This approach involves service interruption and careful planning but can sometimes avoid more disruptive activities like excavation or pipe cutting.

Step 5 – Last Resort: Excavation and Cutting the Pipeline

In severe cases—such as heavy deformation, a collapsed pipe, or an immovable plug of wax or debris—the final option may be to excavate and cut the pipeline at or near the pig’s location.

This is truly a last resort. Excavation and cutting involve significant cost, extended downtime, and substantial post-work requirements. 

After cutting out the section containing the pig, the pipeline must be repaired or replaced, welds inspected, protective coatings restored, and cathodic protection systems re-evaluated. The line will also require re-testing before being returned to service.

Although disruptive, excavation and cutting must still be a controlled, carefully engineered activity. It should only proceed after other options have been evaluated and deemed impractical or unsafe.

When to Stop and Call a Stuck Pig Specialist?

Knowing when to stop experimenting and call in specialist support is critical. Warning signs include rising risk of overpressure, conflicting information about pig type or location, and increasing uncertainty about the cause of the blockage. 

Complex facilities, subsea systems, river crossings, and high-consequence areas also demand a higher level of caution.

Specialists in pigging and pipeline integrity bring experience, modeling tools, and proven procedures to the problem. 

They can simulate hydraulic conditions, analyze pig behavior, and evaluate structural risks before a small issue becomes a major event. Bringing in expert help early often reduces overall cost, downtime, and risk.

How to Prevent Stuck Pigs in the Future?

Prevention is always better than recovery. Designing and operating pipelines with pigging in mind significantly reduces the chance of stuck pigs.

Pipelines should be designed for piggability, with properly barred tees, suitable bend radii, and valves that open fully to a clear bore. During planning, operators should consider how pigs will traverse each fitting, transition, and station.

Pre-cleaning and staged pigging help remove bulk debris and reduce wax or scale gradually, rather than relying on a single aggressive run. 

Matching pig design to the pipeline is essential: that includes choosing the correct pig type, diameter, seal configuration, and bypass settings for the line’s product, pressure, and geometry.

Before launching a pig, valves and fittings must be confirmed fully open and free of internal restrictions. 

Caliper or gauging tools can be run ahead of critical or expensive pigs to detect dents, buckles, or bore reductions that might trap a tool.

These best practices are closely aligned with the broader services offered by APS, including pre-commissioning, cleaning, smart pigging, internal coating, and condition analysis. 

Together, they form a comprehensive approach to minimizing stuck pig risk and maintaining pipeline integrity.

FAQs – How to Remove Stuck Pigs

What is the first thing to do when a pipeline pig gets stuck?

The first step is to stabilize the system and confirm that the pig is truly stuck. Verify pressure and flow conditions, review tracking and signaller data, and ensure the line is within safe operating limits. Do not immediately increase pressure beyond normal limits or improvise corrective actions without a plan.

Can I just increase pressure to move a stuck pig?

No. Simply increasing pressure can be dangerous and may exceed the pipeline’s design limits or MAOP. Any pressure changes must be controlled, within defined limits, and part of a structured recovery plan.

How do you locate a stuck pipeline pig underground or subsea?

Location methods include pig signallers, tracking logs, pressure and temperature analysis, acoustic tools, and specialized tracking technologies. For buried or subsea lines, advanced tools and experienced specialists are often required to pinpoint the pig accurately.

Is it safe to send another pig to push a stuck pig out?

Sending a rescue pig can be effective, but it must be carefully engineered. An improperly sized or configured rescue pig can make the blockage worse or become stuck itself. This option should only be used after thorough evaluation of the pipeline and the original pig.

When do you have to cut the pipeline to remove a pig?

Cutting the pipeline is a last resort, typically used when other methods fail or when there is significant pipe damage or an immovable obstruction. It requires excavation, careful planning, welding and coating repair, and re-testing before the line returns to service.

How can I prevent pigs from getting stuck in future pigging runs?

Prevention involves designing for piggability, staging cleaning runs, selecting the right pig type and size, verifying valve positions, and using caliper or gauging tools to detect bore restrictions in advance. Regular inspection and maintenance also reduce the risk of debris-related blockages.

When should I call a stuck pig specialist like American Pipeline Solutions?

You should reach out for specialist support as soon as there is uncertainty about the pig’s location, cause of the blockage, or best path forward. Complex systems, high-consequence areas, and signs of increasing risk all warrant early involvement from experienced pigging professionals like APS.

Magnetic Pigs: What They Are and How They’re Used?

When it comes to maintaining safe, efficient, and inspection-ready pipelines, removing ferrous debris is one of the most overlooked yet critical steps. Small fragments of welding rods, mill scale, or rust particles left behind after construction or normal operations can compromise inspection data, damage internal coatings, and cause unnecessary downtime. That’s where magnetic pigs come in — specialized pipeline cleaning tools designed to collect and retain magnetic debris before it becomes a problem.

At American Pipeline Solutions (APS), magnetic pigs are an integral part of our broader Cleaning & Conditioning and Inspection & Integrity Support services. We use them to prepare lines for in-line inspection (ILI), maintain flow efficiency, and support integrity management programs across oil, gas, water, and industrial systems nationwide.

What Is a Magnetic Pig?

A magnetic pig is a type of cleaning or conditioning tool equipped with high-strength magnets — usually neodymium or rare-earth types — that attract and capture ferrous materials inside a pipeline. The magnets are either mounted in boxes on a steel mandrel body or molded into polyurethane cups and discs for smaller diameters.

As the pig travels through the line, driven by product flow or compressed medium, the magnetic field attracts and holds metallic particles like scale, rust flakes, welding slag, and stray hardware. When retrieved, these contaminants adhere to the pig body or magnet housings, keeping them out of downstream equipment and preventing interference with future inspections.

It’s important to distinguish magnetic pigs from smart pigs. Smart pigs, often called MFL (Magnetic Flux Leakage) tools, use magnetization to detect wall loss and corrosion during inspection. Magnetic cleaning pigs, on the other hand, use magnets to collect debris, not to measure defects. They serve different roles within the same integrity workflow.

How Magnetic Pigs Work?

Magnetic pigs operate on a simple but powerful principle — magnetic attraction. As the pig moves through the line, it creates a strong magnetic field that draws ferrous particles away from the pipe wall and holds them on the pig’s surface.

This process serves two key purposes. First, it removes debris that can restrict flow or damage equipment. Second, it improves ILI accuracy. If iron particles remain on the pipe wall, they can distort magnetic readings or trigger false corrosion signals during inspection runs. A properly executed magnetic pig run significantly improves data quality and helps integrity engineers make better-informed decisions.

Many magnetic pigs also support above-ground tracking. Because the pig body is magnetized, its location can be detected by an AGM (Above Ground Marker) or magnetometer as it passes, allowing technicians to verify progress and confirm arrival without interrupting operations.

When Magnetic Pigs Are Used?

Magnetic pigs can be applied in nearly every stage of a pipeline’s lifecycle, but they deliver the most value in three scenarios:

1. Pre-Commissioning and Post-Construction

After welding, hydrotesting, or drying, pipelines often contain metallic residues — small offcuts, welding slag, or mill scale — that can pose long-term risks if left behind. A magnetic pig pass collects these remnants efficiently, protecting valves, meters, and inspection tools downstream.

APS routinely incorporates magnetic runs into our commissioning programs, especially for newly built or rehabilitated lines, to ensure a clean and safe transition to service.

2. Routine Operations and Maintenance

During normal operations, corrosion and wear can still generate ferrous debris. Over time, this material accumulates in low spots or slow-flow sections, contributing to pressure drop and inconsistent throughput. Periodic magnetic pig runs keep these systems clear, extend cleaning intervals, and prevent issues before they escalate.

3. Pre-Inspection Preparation

Before deploying a high-value MFL or UT inspection tool, it’s crucial to remove any remaining magnetic debris that could interfere with the sensors. APS integrates magnetic pigs into inspection readiness sequences to deliver the cleanest possible line environment, ensuring accurate readings and efficient inspection scheduling.

Common Configurations and Sizes

Magnetic pigs come in multiple configurations depending on the pipeline’s design and the task at hand.

• Mandrel-body pigs are most common for diameters above 6 inches. They feature steel cores fitted with polyurethane cups or discs for sealing and drive, along with magnet boxes bolted to the body.

• Foam or urethane pigs with embedded magnets are used in smaller or more complex systems where flexibility and tight bends are a concern.

Typical sizes range from 4 inches up to 56 inches, with magnet strength and placement tailored to the line’s diameter, wall material, and debris profile. APS evaluates these parameters during project scoping to choose the configuration that captures the most debris with minimal friction or risk of hang-up.

Magnetic Pigs vs. Other Cleaning Pigs

Magnetic pigs are part of a larger family of cleaning tools, each designed for a specific function. Brush pigs use steel or wire brushes to remove scale and hardened deposits; cup or disc pigs provide strong sealing for liquid displacement and scraping; foam pigs help dry or displace product after testing.

A magnetic pig doesn’t replace these tools — it complements them. In many projects, APS runs a cleaning sequence that might include a brush pig to loosen debris, followed by a magnetic pig to collect it, and finally a gauging or verification pig to confirm line clearance before inspection. This sequence provides the best combination of mechanical cleaning, debris removal, and verification.

Integration in a Typical Inspection Plan

For large-diameter pipelines preparing for in-line inspection, APS often deploys magnetic pigs as part of a defined pre-ILI workflow.

A standard sequence might look like this:

1. Initial mechanical cleaning: brush or scraper pig to remove bulk debris.

2. Magnetic pig run: collect ferrous particles dislodged by earlier passes.

3. Gauging pig run: confirm internal diameter and ensure obstruction-free passage.

4. Inspection tool run: MFL or UT tool collects data for analysis.

This structured approach delivers cleaner signals, reduces tool wear, and improves overall inspection efficiency.

Tracking and Locating Magnetic Pigs

Because of their inherent magnetization, magnetic pigs are easy to track. As the tool moves through the pipeline, it generates a magnetic signature that can be detected by Above Ground Markers (AGMs) or handheld magnetometers. Field crews use these readings to confirm the pig’s progress, identify any delays, and validate arrival times at each trap.

Tracking also adds a layer of safety and operational control — especially in multi-segment lines or areas with elevation changes — by ensuring that the pig is accounted for at all times during the run.

Benefits of Magnetic Pigs

Incorporating magnetic pigs into a maintenance or inspection plan offers multiple advantages:

• Improved flow efficiency: removing metallic debris restores the internal diameter and consistent flow.

• Enhanced ILI accuracy: clean walls lead to better magnetic flux readings and fewer false indications.

• Reduced equipment damage: prevents abrasive particles from damaging valves, meters, or sensors.

• Cleaner operations: debris collection reduces contamination risk during product changeovers.

• Regulatory compliance: documented cleaning and debris reports strengthen integrity and safety records.

For operators managing extensive pipeline networks, these benefits translate into fewer disruptions, more reliable inspection data, and lower total maintenance costs.

Limitations and Considerations

Like any tool, magnetic pigs must be used correctly to deliver the expected results. They are not designed to replace aggressive mechanical cleaning when heavy scale or hardened deposits are present. In such cases, APS typically precedes the magnetic pass with brush or bi-directional pigs to break up material first.

Operators should also account for coating condition and pipeline geometry. Poorly bonded coatings can be damaged by strong magnetic contact, and tight bends or internal features can trap heavily loaded pigs. APS evaluates these risks during scoping and includes control measures such as differential pressure limits, bypass ports, and real-time tracking.

After each run, collected debris must be removed and disposed of safely. Because magnets retain the particles strongly, crews follow strict cleaning and handling procedures to avoid injuries or contamination.

How to Select the Right Magnetic Pig?

Selecting the correct magnetic pig depends on multiple factors: pipeline diameter, geometry, product type, debris characteristics, and inspection objectives. APS engineers evaluate these variables as part of every cleaning and inspection plan, ensuring each tool is optimized for the line’s design and condition.

We also consider the expected debris load and propulsion method — whether the pig will be driven by liquid, gas, or air — and confirm compatibility with AGM tracking systems when location verification is required. This process helps prevent delays and ensures that each run delivers the expected outcome safely.

Frequently Asked Questions

Are magnetic pigs the same as smart pigs?
No. Smart pigs collect data using magnetic flux leakage (MFL) technology, while magnetic cleaning pigs use magnets to remove ferrous debris. They are often used in sequence — magnetic cleaning first, smart pig inspection second.

Can magnetic pigs damage internal coatings?
When used correctly and selected based on coating type and line condition, magnetic pigs do not damage coatings. APS assesses coating adhesion and wall condition before recommending magnetic cleaning.

What sizes are available?
Standard magnetic pigs cover diameters from 4 to 56 inches, with custom designs available for larger or specialized applications.

Can magnetic pigs be tracked above ground?
Yes. Their magnetic signature can be detected by AGMs or magnetometers, allowing real-time confirmation of the pig’s position during a run.

Do I still need brush or foam pigs?
Often yes. Magnetic pigs target ferrous debris, while brush or foam pigs remove organic or non-magnetic materials. APS typically uses a combination for complete cleaning.

Where do magnetic pigs fit in an ILI preparation plan?
They are generally run after mechanical cleaning and before the inspection tool to maximize ILI accuracy and protect sensors.

Why Pipeline Gauging Matters (2026 Guide)

Before any inspection, cleaning, or commissioning, one simple question defines whether a pipeline is ready for the next stage: Is it truly clear and piggable?

Pipeline gauging is the industry’s most reliable way to answer that question. By proving that the line is free from obstructions, dents, and internal restrictions, it lays the foundation for every downstream process — from pre-commissioning and cleaning to smart pig inspections and internal coatings.

At American Pipeline Solutions (APS), gauging is more than a procedural step. It’s a critical integrity assurance measure that prevents costly tool hang-ups, project delays, and integrity failures. In this guide, we’ll explain what pipeline gauging is, how it works, and why it’s a non-negotiable step in modern pipeline operations.

What Pipeline Gauging Proves?

Pipeline gauging is the process of verifying a pipeline’s internal bore and confirming that it is smooth, continuous, and unobstructed.

A simple gauge pig — equipped with a thin, deformable metal plate sized slightly smaller than the minimum internal diameter — is propelled through the line. If the plate completes its journey without bending or tearing, it confirms that the line can safely accommodate cleaning pigs, inspection tools, or product flow.

If the plate returns damaged, it’s a clear signal that something inside the pipeline requires attention before proceeding.

At APS, gauging is performed:

• After new construction or tie-ins

• Before Smart Pig or ILI (In-Line Inspection) runs

• Following pre-commissioning cleaning

• After internal coating or rehabilitation work

• Whenever debris or deformation is suspected

This simple test protects millions of dollars in assets and weeks of potential downtime by ensuring that the system is physically ready for operation.

How the Gauging Process Works?

The process begins long before a pig enters the launcher. APS engineers start by reviewing pipeline drawings, feature lists, and minimum bore data. This allows the team to select the correct gauge plate size — usually about 95% of the smallest internal diameter — and the right pig body type for the system.

The gauging pig is then launched and tracked from start to finish using advanced pig tracking systems, ensuring it completes the full run. Upon retrieval, technicians inspect the plate for scratches, dents, or deformation. Even minor marks provide valuable diagnostic clues about potential restrictions or weld protrusions.

Every APS gauging run includes:

• Precise pre-job engineering

• Verified plate sizing and calibration

• Real-time pig tracking

• Detailed post-run inspection and reporting

This combination of preparation, precision, and documentation guarantees a clear view of the pipeline’s internal condition before moving on to more advanced steps.

What Gauging Reveals (and Why It Matters)?

A pipeline’s interior can be deceptive. Even after construction or cleaning, hidden issues may remain that jeopardize inspection or product flow. Gauging exposes those unseen risks before they escalate.

Common findings include:

• Weld penetration or misalignment

• Dents, buckles, or ovality

• Internal coating drips or excess epoxy

• Debris left behind from conventional pigging or flushing

• Valves not fully open or incorrectly oriented

A distorted or damaged gauge plate provides early warning of such defects. APS technicians use this insight to recommend corrective actions — whether it’s targeted cleaning, Ice Pigging™, localized repair, or further investigation using Smart Pig technology.

The result is a cleaner, safer, and more reliable system — validated before any high-value tools or products are introduced.

The Business Case for Gauging

It’s easy to underestimate the value of a simple gauge run until a tool gets stuck. A lodged cleaning or inspection pig can halt operations, require excavation, and delay projects for days or weeks.

Gauging eliminates that uncertainty and protects the bottom line in four key ways:

Prevents Expensive Failures

By detecting restrictions early, operators avoid the cost of retrieval operations, pipeline downtime, and emergency digs.

Supports Commissioning Readiness

During Pipeline Pre-Commissioning, gauging confirms that the bore is smooth and clear before hydrotesting, dewatering, and drying. This ensures that subsequent pigs — whether foam, brush, or ice slurry — can travel safely through the line.

Ensures Accurate Inspection Results

For Pipeline Inspection & Condition Analysis, a clean, obstruction-free line means smarter data and fewer tool interruptions. Gauging guarantees that Smart Pig sensors can capture reliable readings for corrosion, leaks, or metal loss.

Demonstrates Regulatory Compliance

Industry standards (API, ASME, and PHMSA) recommend gauging as a formal verification step. Documenting this process strengthens your integrity management records and demonstrates operational diligence.

When compared to the cost of tool loss or unplanned shutdowns, a gauging run is one of the most cost-effective safety measures an operator can invest in.

Inside a Typical APS Gauging Run

APS follows a structured, data-driven process on every gauging project:

1. Planning & Assessment – Review design drawings, confirm minimum ID, and identify potential restrictions.

2. Pre-Cleaning – If needed, APS performs Conventional Pigging & Swabbing or Ice Pigging™ to remove loose debris that might affect results.

3. Gauge Run Execution – Launch and track the gauge pig, recording pressure, flow, and speed data.

4. Plate Inspection – Examine the retrieved gauge plate for scarring or bending; photograph and document the findings.

5. Reporting & Recommendations – Deliver a digital report with inspection photos, run data, and next-step guidance.

This systematic approach not only provides a pass/fail outcome but also generates actionable intelligence for follow-up decisions.

Interpreting Gauge Plate Results

A clean plate means the pipeline is piggable and ready for subsequent operations. A scratched or bent plate indicates there’s a restriction or deformation.

Minor scrapes may point to leftover debris, while deep creases can signal serious issues like weld intrusion or internal collapse. APS engineers use deformation patterns, run pressure data, and tracking logs to estimate where along the pipeline the interference occurred.

Depending on severity, the next step might include:

• Additional cleaning or Ice Pigging™ runs

• Targeted section repair

• A geometry pig or Smart Pig inspection for precise mapping

• Delaying Internal Pipe Coating until the bore is confirmed clear

This evidence-based escalation ensures corrective work is both efficient and justified.

When to Perform Gauging?

Gauging isn’t just for oil and gas systems it’s essential across water, wastewater, chemical, and industrial pipelines. The timing, however, is critical.

You should gauge:

• Before commissioning or product introduction (to confirm readiness)

• After construction or tie-in work (to catch weld protrusions or misalignments)

• Before any ILI run (to protect Smart Pig tools)

• After coating or rehabilitation (to verify proper cure and internal clearance)

• When a restriction is suspected due to abnormal pressure or flow

In every case, gauging acts as the bridge between “theoretical design” and “verified readiness.”

Avoiding Common Mistakes

While gauging is conceptually simple, poor execution can compromise results. APS frequently encounters three avoidable errors in the field:

1. Skipping Pre-Cleaning: Residual debris can give false readings and damage plates.

2. Incorrect Plate Sizing: Oversized plates risk getting stuck; undersized ones may miss deformations.

3. Lack of Tracking: Without monitoring, locating a slowed or stuck pig becomes difficult and expensive.

APS mitigates these risks with precise sizing, redundant tracking methods, and strict documentation standards — ensuring every gauging run produces reliable, verifiable data.

How Gauging Fits Within APS’s Full Pipeline Services?

Because APS delivers end-to-end pipeline integrity and maintenance solutions, gauging seamlessly connects with several other services:

• Pipeline Inspection & Condition Analysis: Gauge runs confirm that Smart Pig tools can safely navigate the line and collect high-quality data.

• Pipeline Pre-Commissioning: Gauging validates bore condition before hydrotesting, drying, and pressurization.

• Ice Pigging™ Services: Ideal for post-gauge cleaning or decontamination when debris or microbial buildup is identified.

• Conventional Pigging & Swabbing: Used for debris removal ahead of or after gauging to maintain flow assurance.

• Internal Pipe Coating: Performed only once gauging verifies a clean, obstruction-free surface.

• Pipeline Mapping & Consulting: Gauging data integrates directly into system maps and condition reports, guiding strategic maintenance planning.

This integration ensures operators receive a single, data-driven solution for pipeline integrity from start to finish.

Real-World Insight

In one APS project, a 24-inch transmission line was scheduled for smart pig inspection following tie-in work. A preliminary gauge run revealed the plate returned with a deep radial crease — later traced to a misaligned weld in a short transition spool. The section was corrected and re-gauged successfully, allowing the ILI tool to pass without issue. The proactive step saved several days of downtime and costly excavation.

That’s the value of gauging: catching the unseen, before it becomes the unmanageable.

Conclusion

Pipeline gauging might appear straightforward, but it’s one of the most valuable assurance tools in the entire pipeline lifecycle. It provides confidence that your system is clean, clear, and ready — whether you’re about to run an intelligent inspection, commission a new asset, or apply a protective coating.

At American Pipeline Solutions, gauging forms the backbone of our commitment to integrity, reliability, and operational excellence. When combined with our advanced pigging, inspection, coating, and mapping services, it ensures your pipeline isn’t just built to last — it’s proven to perform.

What is Foam Pigging?

Foam pigging is a specialized pipeline cleaning method that uses foam pigs—flexible, foam-based cleaning tools that conform to the shape of the pipeline. These foam pigs can be enhanced with abrasive materials or coated to address specific cleaning needs.

How Foam Pigging Works

1. Insertion: A foam pig is inserted into the pipeline and propelled by compressed air, water, or other fluids.

2. Scrubbing and Flexibility: The pig conforms to the shape of the pipeline, scrubbing and removing debris, sediment, and light blockages.

3. Collection and Removal: As the foam pig moves through, it collects residue, which is flushed out upon exit.

Foam pigging is highly versatile, making it suitable for pipelines with bends, diameter changes, or delicate materials that cannot withstand high pressure. The soft yet effective action of foam pigs is especially valuable for systems that require gentle but thorough cleaning.

What is Jetting?

Jetting, also known as hydro-jetting, is a high-pressure cleaning method that blasts water through the pipeline to remove blockages, buildup, and debris. This method is especially effective for hard obstructions but requires caution for delicate or aging pipelines.

How Jetting Works

1. Setup: Jetting equipment is positioned at the pipe’s entry point, with high-pressure pumps connected to specialized nozzles.

2. High-Pressure Cleaning: Water is propelled through the nozzles at pressures up to 4000 psi (pounds per square inch), depending on the pipe's condition.

3. Debris Flushing: The intense water pressure breaks down debris and flushes it out, clearing the pipeline.

Jetting is commonly used in pipelines that can handle high pressure, as it offers rapid clearing of hard blockages and is effective in removing tree roots, mineral deposits, and more.

Pros and Cons of Foam Pigging

Pros:

• Easily cleans long pipelines (>1000’)

FAQs:

What is foam pigging in pipeline cleaning?
Foam pigging is a cleaning method that uses flexible foam pigs to travel through the pipeline, scrub the walls, and carry out debris. The foam pig is propelled by air, water, or product and conforms to bends and diameter changes. This makes it ideal for long runs, older lines, and systems that can’t tolerate high pressure.

How is foam pigging different from jetting?

Foam pigging relies on a physical foam pig that wipes and carries debris out of the line, while jetting (hydro-jetting) uses high-pressure water to blast away deposits. Foam pigging is gentler, uses less water, and can be run in live systems. Jetting delivers more aggressive cleaning power but requires drained lines and can stress fragile pipe.

When should I choose foam pigging instead of jetting?

Foam pigging is typically the better choice for pipelines with many bends, diameter changes, or older materials that may not tolerate high pressure. It’s also preferred when the line cannot easily be taken offline or when water use must be minimized. APS often recommends foam pigging for delicate, complex, or long (>1000’) sections.

Is jetting safe for all pipelines?

Jetting can be very effective, but it is not suitable for every pipeline. Because it uses high water pressures—often up to 4,000 psi—it is best applied to newer, robust materials that can handle the stress. On older, corroded, or fragile lines, jetting can cause damage, so APS evaluates wall condition and risk before recommending this method.

Can foam pigging remove hard blockages like roots or heavy scale?

Foam pigging is excellent for light to moderate debris, soft sediments, and general cleaning, but it is less effective on very hard obstructions such as tree roots or severe mineral scale. In those cases, jetting or more aggressive mechanical methods may be required. APS often combines foam pigs with other tools as part of a broader cleaning program.

Does jetting use more water than foam pigging?

Yes. Jetting typically consumes significantly more water because it relies on continuous high-pressure flow to break up obstructions and flush debris. Foam pigging uses far less water, since the foam pig does most of the mechanical cleaning as it travels through the line. For sites with limited water availability, foam pigging is often the more practical choice.

Can foam pigging be performed while the pipeline is in service?

In many systems, foam pigging can be carried out with product or fluid still moving, as the pig is propelled by that flow. This reduces downtime compared to jetting, which usually requires the line to be drained. APS always reviews operating conditions, media, and safety requirements before planning an in-service foam pigging run.

How far can jetting and foam pigging reach in one operation?

Foam pigging is well suited to long runs and can efficiently clean pipelines longer than 1,000 feet in a single pass. Jetting, by contrast, is typically limited to shorter reaches, often in the 1,000–1,500 foot range, depending on access and equipment. APS considers length, access points, and line geometry when recommending a cleaning method.

Can I use both foam pigging and jetting on the same pipeline?

Yes. In some projects, a combined approach delivers the best result. For example, targeted jetting may be used to break up heavy deposits in a short, accessible section, followed by foam pigging to sweep residual debris through longer or more complex sections. APS designs cleaning plans that use the right tools in the right sequence for each line.

Types of Pipeline Pigs and Their Applications

• Cleaning Pigs

Cleaning pigs are the foundation of maintenance programs. They are designed to remove wax, sludge, biofilm, or scale deposits that build up over time. Depending on the severity of fouling, they can range from flexible foam pigs for routine sweeps to more aggressive scraper or bristle pigs for hard deposits. Selecting the right cleaning pig ensures that buildup is addressed without damaging the pipe walls.

• Inspection Pigs (Smart Pigs)

Smart pigs carry advanced technology to detect defects inside the pipeline. Using tools such as magnetic flux leakage (MFL), ultrasonic testing (UT), or caliper sensors, these pigs capture detailed information about corrosion, cracks, and wall thickness variations. Inspection pigs transform pigging from a cleaning operation into a sophisticated diagnostic tool that helps operators plan repairs and extend pipeline life.

• Specialty Pigs

Some pipelines require pigs with unique capabilities. Specialty pigs are used for product separation, sealing leaks, or even performing targeted repairs. These designs often involve custom engineering to meet specific operational challenges.

• Advanced and Hybrid Pigs

Modern pigging has evolved to include hybrid pigs that combine multiple functions. Speed-control pigs, for example, regulate velocity in high-flow pipelines, while bypass pigs use controlled leakage to prevent stalling and reduce pressure buildup. These innovations reflect how pig design continues to adapt to increasingly complex pipeline environments.

Key Factors in Optimizing Pig Design

Pipeline Configuration

The geometry of a pipeline is one of the most important design considerations. Changes in diameter, sharp bends, valves, and tees require pigs that are both resilient and flexible. Articulated pigs or expandable-seal designs allow for effective navigation through difficult routes.

Operating Conditions

Pipelines operate under a wide range of pressures, temperatures, and flow regimes. A pig that performs well in a low-pressure water line may fail in a high-pressure gas system. Understanding these conditions is essential for choosing seals, coatings, and structural components that will withstand the environment.

Deposits and Fouling

Different pipelines experience different types of deposits. A crude oil line may suffer from wax accumulation, while a water pipeline might face biofilm or mineral scale. The pig must be designed with cleaning elements suited to the specific deposit, whether soft and flexible for delicate cleaning or rigid and abrasive for stubborn buildup.

Speed and Pressure Control

Maintaining a stable pigging speed is critical, especially for inspection operations. If the pig travels too quickly, sensor data becomes unreliable; too slowly, and it may stall. Speed-control designs, including bypass features and pressure regulation, allow pigs to maintain the correct velocity across varying conditions.

Seals and Bypass Systems

Seals are central to pig performance, ensuring that debris is pushed ahead of the pig rather than bypassing around it. At the same time, bypass systems can be engineered to prevent pressure lock or to allow limited flow, providing stability and control in complex environments.

Inspection Payloads

For inspection pigs, the design must balance navigational ability with the weight and power requirements of the onboard sensors. Magnetic, ultrasonic, and caliper tools each impose specific demands, and the pig must be engineered to accommodate them without sacrificing mobility.

Customizing Pig Design

Pipeline Diameter and Configuration

The pipeline's diameter and configuration are critical factors in pig design. Pigs must be sized correctly and capable of navigating through complex pipeline routes, including bends, valves, and diameter changes. Adaptable and resilient pig designs ensure effective navigation and task execution.

Material and Coating Selection

Material selection for pigs is influenced by the pipeline's environment and the medium it transports. Corrosive environments might necessitate corrosion-resistant materials, while softer, non-abrasive materials are preferable for pipelines carrying sensitive products.

Cleaning Pig Design

The design of cleaning pigs is dictated by the nature of the debris and the level of cleaning required. Heavy deposits might require pigs with aggressive scraping elements, while routine maintenance can be managed by softer, more flexible designs.

Advanced Sensor Integration in Inspection Pigs

The complexity of inspection pigs depends on the level of detail required for the inspection. High-resolution sensors, magnetic flux leakage tools, or ultrasonic devices are integrated based on the specific inspection needs, such as detecting cracks, corrosion, or wall thickness anomalies.

Specialty Pigs for Unique Tasks

Specialty pigs are designed for specific challenges like sealing damaged sections, separating product batches, or performing targeted repairs. Their design requires innovative engineering to fulfill the task effectively.

Common Challenges in Pig Design

Pig Stalling and Sticking

Stalling is one of the most frequent challenges in pigging operations. It often occurs when debris accumulates ahead of the pig, seals are oversized, or the pig encounters a sharp diameter change. Solutions include articulated designs, carefully sized seals, and bypass ports that relieve excess pressure.

Seal Blow-Over

Seal blow-over happens when high differential pressure forces fluid around the pig rather than pushing it forward. This reduces cleaning efficiency and can damage the seals themselves. Optimized seal geometry and resilient compounds are essential to prevent this issue.

Speed Instability

Fluctuations in velocity compromise both cleaning and inspection. Oscillations in speed can cause uneven debris removal or inconsistent inspection data. Pigs with built-in speed-control mechanisms maintain stability even under varying flow conditions.

Multi-Diameter Pipelines

Pipelines that transition between diameters pose a unique challenge. Without flexible designs, pigs may lose contact in larger sections or become stuck in smaller ones. Dual-diameter pigs or expandable seals address this issue effectively.

Data Limitations

For inspection pigs, carrying multiple sensors requires careful balancing of power, weight, and storage capacity. Innovations in lightweight sensor technology and real-time data transmission are helping overcome these constraints.

Advancements in Pigging Technology

The field of pigging is rapidly advancing, driven by new technologies and engineering approaches. Artificial intelligence is now used to analyze inspection data, identifying patterns of corrosion or stress that might be missed by human reviewers. Real-time data transmission allows operators to monitor conditions as the pig travels through the line, providing immediate insights.

Adaptive pigs capable of adjusting their seals or bypass features on the fly are being developed to handle pipelines with unpredictable conditions. Improvements in seal design and surface protection have also increased durability, making pigs more reliable in corrosive or abrasive environments. Integration with three-dimensional mapping systems now provides operators with highly accurate digital models of their pipelines, supporting better maintenance planning.

Practical Steps to Choosing the Right Pig

Optimizing pig design requires a structured process. It begins with a detailed survey of the pipeline to understand its geometry, flow conditions, and fouling history. Computational models can then simulate pig performance, predicting factors such as pressure differential and travel speed.

Once a design is chosen, it is prototyped and tested under controlled conditions before being deployed in the field. Field trials provide data that can be fed back into the design process, allowing for iterative refinement. This cycle of assessment, design, validation, and feedback ensures that each pig is suited to its specific task.

Industry Applications and Lessons Learned

Across industries, optimized pig design has proven its value. In water utilities, combining flexible cleaning pigs with Ice Pigging™ has significantly improved water quality by removing biofilms. In gas transmission pipelines, smart pigs equipped with MFL sensors have detected early-stage corrosion, preventing costly leaks. Oil pipelines with varying diameters have successfully deployed dual-seal pigs that maintain consistent cleaning and inspection across all sections.

These examples illustrate the importance of tailoring pig design to operational challenges rather than relying on one-size-fits-all solutions.

Safety, Environmental, and Operational Considerations

Safety is at the heart of every pigging operation. In high-pressure or hazardous pipelines, pigs must be engineered to operate reliably without risking blowout or equipment failure. Environmental responsibility is equally critical, with designs that minimize contamination risks and ensure that all debris is safely managed.

Operational considerations include the ease of launching and receiving pigs, the training required for operators, and the long-term maintenance of pigging equipment. At APS, we emphasize not only advanced design but also safe, practical implementation.

Training and Knowledge Transfer

Even the most advanced pig designs require skilled personnel to achieve consistent results. Without proper training, operators may face challenges during launching, receiving, or interpreting inspection data. Training programs equip teams with the knowledge to handle advanced pigging technologies, troubleshoot issues in real time, and apply inspection findings to long-term pipeline management.

At APS, we believe in knowledge transfer as part of every project. By working alongside client teams, we ensure that operators not only benefit from our immediate services but also gain the skills to maintain pipeline performance well into the future.

APS uses this data to support pipeline condition assessments, prioritize inspection or pressure pipe inspection, and plan targeted maintenance. Knowing exactly where features and deviations are located also makes future inspection and repair work safer and more efficient.

Can gyroscopic pipeline mapping data be integrated with our GIS or asset management system?

Yes. APS structures gyroscopic pipeline mapping outputs so they can be integrated into GIS platforms and utility asset management systems. This allows operators to overlay pipeline alignment, depth, and orientation data with other system information, improving planning, risk assessment, emergency response, and long-term capital project decisions across the network.

How does gyroscopic mapping help with emergency response and regulatory compliance?

During events like water main breaks, gas leaks, or suspected pipeline failures, accurate alignment data allows crews to locate and access the problem area faster and with less trial-and-error digging. APS’s gyroscopic mapping reports also support regulatory and integrity documentation by providing traceable records of pipeline location, orientation, and condition indicators that can be referenced in safety, risk, and compliance programs.

A First Ever For Ice Pigging™ At A New York City Area Medical Facility

Ice Pigging™ is an advanced and sustainable cleaning method for potable water distribution systems, raw water, processed water, and wastewater force mains. The method involves pumping a slurry of ice into a main through a hydrant or other existing fittings throughout the system and using pressure in the lines to push the ice pig downstream to an exit point through a similar fitting. Filling 20 to 30 percent of a pipe’s volume, the ice slurry cleans with a shear force between 100 and 1,000 times greater than water alone and provides more effective cleaning, and uses significantly less water than traditional flushing methods.

An ice pig works in a way like a glacier does. Rather than bulldozing sediment and biofilm through a line, it consumes the material into the ice. The ice pig enters and exits through a hydrant and or other existing fittings, therefore specialized launching and retrieval stations are not required as with mechanical pigging. Customer service isolation usually is not necessary with Ice Pigging™. Inorganic sediments and debris like iron and manganese can accumulate in or on water distribution system pipe walls causing pipeline restrictions and build-up. These restricted flows can cause increased discoloration, taste, and the quality of the water provided to the customer. Other technologies like water flushing and water-jetting are inefficient and sometimes ineffective.

Ice Pigging™ is an innovative, low-risk, award-winning advanced pipeline cleaning technology to clean drinking water pipes, sewer force mains, and siphons. The ice slurry can be inserted and removed through fire hydrants, (figure 1) line taps, and other existing fittings in a distribution system. Ice Pigging™ harnesses the characteristics of a semi-solid material that can be pumped like a liquid but behaves like a solid (figure 2) once the pig is formed in the pipe. Ice Pigging™ uses approximately 50 percent less water than standard water flushing and takes significantly less time. Typically, a section of pipeline being cleaned is out of service for no more than 60 minutes. A main feature of Ice Pigging™ is that it cannot get stuck permanently. If for some reason the pig were to get stuck, time would be allowed for the ice to melt and flush it from the pipeline. Ice Pigging™ is not affected by pipe bends, changes in diameter or butterfly valves which all pose problems for other pipeline cleaning technologies. Ice Pigging™ is far less intrusive to any system it’s used on.

The Benefits

Ice Pigging™ represents a sustainable best practice and unique approach to pipeline cleaning. The advantages include:

• Exceptionally low risk

• Produces quantifiable results

• Injects through existing fittings

• System pressure & flow pushes the ice

• Efficient, rapid, and environmentally friendly

• Uses up to 50% less water than standard flushing

• Effectively removes biofilm, iron, manganese, and sediments

• Suitable for pipes of all sizes up to 24 inches and materials

• Combines operational benefits of flushing with the impact of solid pigging

Ice slurry is pumped like a liquid to form a solid known as an “ice-pig” once pumped into the pipeline.

Methodology

To maintain the correct consistency of the ice pig a freezing-point depressant is used. The depressant being used is a food-grade fine table salt which is approved by the National Science Foundation (NSF). This is added to the water in the tank which is always sourced from a public potable water supply. The current maximum batch capacity is 2,700 gallons.

The brine is made in a 316-stainless steel delivery tanker and hose connections are made to the ice machines that are mounted on a separate trailer (Figure 3). The brine is fed into the ice machines which in turn freezes the liquid and returns it to the delivery tanker. This cycle continues until the ice slurry is at the correct thickness known as the “ice fraction”. Ice fraction measures the amount of ice crystals as a percentage of total volume.

Typically, thicker ice is used on plastic and sound concrete-lined pipes as well as asbestos cement, but when older unlined cast iron pipes are cleaned a thinner ice slurry is used that does not clean as aggressively. The thinner ice slurry will not disturb the tuberculation, which could damage the integrity of an old heavily corroded unlined cast iron pipe.

Ice Delivery

Setup for delivery varies slightly for each different application. A typical setup for a potable water main is shown (Figure 4). The delivery rig connects to the inlet hydrant or other suitable fitting (2 inches or greater tapping with valve control), and at the outlet, a flow analysis system is connected. This system measures and records the flow, pressure, conductivity, turbidity and water temperature as the water and ice are discharged. Once set up, the main is flushed briefly to note and record pre-flush readings. The main is then isolated by the owner’s operators and the required amount of ice is pumped into the main.

At the same time, the outlet hydrant is opened to create a flow and allow water to be displaced as the ice enters the main. With careful control between the inlet and outlet, the flows are balanced to allow slightly more ice into the main than the amount of water being displaced. This has the effect of the ice forming as a pig against a pressurized wall of water.

Once the required amount of ice is in the main, the delivery pump is turned off and the upstream valve is opened to allow the system flow and pressure to “push” the ice pig along the main toward the outlet hydrant. The flow rate is controlled by the outlet operator at this time. As the ice pig approaches the outlet, the conductivity reading will rise as the salty water of the melting pig arrives in front of the pig. The monitoring equipment will show the water temperature falling and conductivity rising as the ice arrives.

At this stage, the operator may collect samples of the ice at regular intervals for later analysis. (Figure 4) The temperature and conductivity will return to pre-flush levels when all the ice and salty water has flushed out of the system and the flushing shall continue briefly to allow the turbidity levels to return to pre-flush levels or lower according to instructions from the owner. The main is then returned to normal service. No disinfection is necessary.

Case History

In October of 2022, American Pipeline Solutions was contracted by a New York City area medical facility to ice pig the main distribution lines bringing potable water into the facility, as well as the eleven different pipelines transporting the water throughout multiple floors of the facility. Ice Pigging™ had not previously been used on interior pipelines, but with extensive knowledge and experience of our technicians, we were confident we would be successful.

The medical facility had sustained water discoloration and taste issues in eleven locations throughout the upper floors of the building. These locations included sinks, toilets, and showers. New sections of the facility had been completed just prior to the onset of the Covid pandemic. These areas were shut down for over a year resulting in water sitting, uncirculated, in the pipelines. Facility administrators believed this was the cause of the discoloration and taste issues. The maintenance team did its best to correct these problems by flushing the system using standard flushing procedures and UDF flushing practices. Nothing worked.

Customer Goals

The facility’s goal was to remove accumulated biofilm, iron, and sediment build up from the water distribution systems both inside and outside the facility.

Solution

APS technicians conducted a pre-project study to prepare a planned schedule of runs designed to clean the eleven compromised sections of the distribution system. The affected pipelines ranged in size from .5” to 8” in diameter. The plan called for use of the advanced Ice Pigging™ cleaning technology. The size of the exterior distribution system together with the interior pipelines required four 10-ton loads of ice slurry to be delivered one load per day. A post project report would identify the chemical, biological, and mechanical results.

Results

Ice Pigging™ accomplished nearly complete removal of accumulated biofilm, iron, and sediment. Thorough removal of these materials assured the facility there was limited risk of their release into the distribution system. Because no build up of these materials in the affected areas is now anticipated, future UDF requirements will be limited and more effective in preventive maintenance.
