Discs

Pigging discs are manufactured from MAXITHANE™, a custom blend of high-performance polyurethane. Discs function as spare parts that can be assembled onto any steel body mandrel pig and can easily be replaced when they wear down. The four pipeline pigging discs we offer are the guide, seal, spacer, and cutter. Each disc serves its own purpose. All of our discs are available for all pipe diameters.
