Oil & Gas Pipeline Services

Core Oil And Gas Pipeline Services From APS

APS does not sell physical products. We deliver service programs that use the right pigging and inspection methods to match the pipeline and the objective.

Pipeline Pre-Commissioning

Pre-commissioning is where project schedules are often won or lost. APS supports pipeline pre-commissioning with structured steps that confirm the line is clean, test-ready, and safe to place into service.

Typical scopes include cleaning and gauging, controlled filling and filtration, hydrostatic testing, dewatering, and drying support. We coordinate these steps to reduce downtime and help teams move from construction completion to operational readiness with confidence.

Pipeline Pigging And Cleaning

Pipeline cleaning is not one-size-fits-all. A foam pig run may be enough for light debris and displacement, while heavier deposits may require a progressive cleaning train. APS designs cleaning runs to remove debris and buildup while keeping risk and pipeline condition in view.

Our cleaning programs are often used to restore flow, stabilize pressure behavior, and prepare pipelines for successful smart pigging runs. If inspection-quality cleaning is required, we plan that from the beginning so the pipeline is ready for reliable data collection.

Caliper Pigging And Gauging

Before high-value tools are run, the pipeline needs to be proven passable. Caliper pigging and gauging help identify restrictions, dents, and ovality that can create stuck-tool risk or compromise inspection results.

APS uses gauging and caliper pigging to confirm bore and piggability, reduce uncertainty, and improve the success rate of downstream cleaning, testing, and inline inspection programs.

Hydrostatic Testing And Nitrogen Pressure Testing

Pressure testing is a critical part of commissioning and integrity validation. APS performs hydrostatic testing to confirm strength and leak-tightness by filling and pressurizing pipeline sections under controlled conditions.

In environments where water-based testing is impractical, such as cold weather, moisture-sensitive systems, or smaller station piping, APS also supports nitrogen pressure testing. We help operators select the right method based on scope, constraints, and project requirements, then deliver the test with strict pressure control and documentation.

Smart Pigging And Pipeline Condition Analysis

When you need more than “pass or fail,” smart pigging provides defect-level insight. APS supports smart pigging programs that evaluate internal condition and help operators prioritize repairs and manage long-term integrity.

These programs often incorporate cleaning and gauging first, followed by inline inspection tools suited to the pipeline and integrity threats. APS then provides Pipeline Inspection / Pipeline Condition Analysis to convert inspection data into clear decisions, what needs immediate attention, what can be monitored, and what should be planned into future maintenance cycles.

Pipeline Mapping Support

Inspection and repair planning depend on knowing where features are located in the real world. APS supports mapping workflows that help tie inspection findings to actionable locations, improving excavation planning, field execution, and integrity reporting.

Internal Pipe Coating

In some oil and gas systems, internal pipe coating can be a useful life-extension option after cleaning and preparation. APS supports internal coating projects where conditions make sense and where the goal is to protect internal surfaces and extend service life.

How APS Runs Oil And Gas Pipeline Projects

Successful pipeline work depends on running the right sequence, not just completing individual tasks. APS uses an engineered approach that keeps safety, schedule, and outcomes aligned.

Step 1: Engineering Review And Job Planning

We start by defining your objective and constraints. That includes reviewing available drawings, operating conditions, access points, and known trouble areas. We confirm piggability, identify risks, and build a sequence that fits the pipeline’s reality, not an ideal scenario.

Step 2: Preparation And Cleaning

Next, APS prepares the line for the work ahead. That may involve progressive pigging, debris removal, or targeted cleaning runs designed to support hydrotesting, dewatering, or inline inspection.

Step 3: Testing Or Inspection Execution

APS executes the planned work safely and consistently, with monitoring and field controls that reduce surprises. Whether the scope is pressure testing, caliper pigging, smart pigging, or an integrated program, our teams focus on predictable execution and documented results.

Step 4: Reporting And Next-Step Decisions

At the end of the project, the goal is not just to complete the run, it is to deliver clarity. APS provides records, observations, and condition-based recommendations that help operators plan repairs, reduce future risk, and schedule the next inspection or maintenance activity with confidence.
