The Role of Poly Pigging in Pipeline Maintenance

Poly pigging is a widely used method in pipeline maintenance that involves sending a polyurethane foam pig—commonly known as a poly pig—through the pipeline to clean, inspect, or remove debris. These pigs are flexible, lightweight, and highly effective in a variety of pipeline applications, making them an essential part of both routine maintenance and system recovery.

What Is a Poly Pig?
A poly pig is made from open-cell or closed-cell polyurethane foam and can be coated with various materials such as wire mesh, silicon carbide, or abrasive strips to enhance its cleaning capabilities. Depending on the application, poly pigs come in different densities and shapes, including bare foam pigs, criss-cross types, and coated pigs.

These pigs are ideal for navigating pipelines with varying diameters, tight bends, or irregular surfaces—situations where rigid pigs might fail or get stuck. Their adaptability makes poly pigging a reliable solution in both new constructions and aging pipeline systems.
