Steel Mandrel Pigs

Steel Mandrel Pigs

Type

Steel mandrel pigs are a more long-term, long-life pig. They consist of a steel mandrel body with easily replaceable sealing elements (cups or discs) and can be equipped with various brush types (spring-loaded, circular, wrap-around) for the cleaning and removing of deposits on the interior pipe wall. Standard configurations include cup, disc, multi-disc, conical cup, and various combinations. These options include adding or substituting cups or discs, special lengths and diameters, gauging plates, articulated joints, transmitter cavities, and magnet packs. The advantage of steel pigs is the ability to replace the wearing components (cups, discs, brushes, etc.), thereby rendering it a new pig.
