Wide adaptability: According to the design requirements of a long-distance pipeline, valves, tee, and elbow parts will be in the pipeline. At the same time, in order to meet the design requirements, such components sometimes differ from the wall thickness of the pipeline. Moreover, the insufficient bending radius of the pipe elbow will cause the internal diameter of the pipe to change. Therefore, there are certain risks when we use conventional pigs. However, the polyurethane foam pig is due to its elastic and compressible properties. Therefore, it can smoothly pass through such pipes without being blocked. At the same time, we can also customize various diameters and structural forms according to the requirements of the pipeline.
