Performance of Polyurethane Screw-type Foam Pig:
The surface of the high-strength polyurethane foam is coated with polyurethane elastomer. It is of spiral type. It has good flexibility, as well as excellent wear resistance and deformation capacity. The diameter variation can reach 50%, and the allowable pipe deformation is 50% to 60%. It is a widely used foam pigging device.
