Steel Mandrel Pigs


Steel pigs are a more long-term, long-life pig. They consist of a steel mandrel body with easily replaceable sealing elements (cups and discs).  Various brush types (spring-loaded, circular, wrap-around) can be utilized for removing deposits on the interior pipe wall.  Standard configurations include cup, disc, multi-disc, conical and hybrid combination styles with various options such as adding or substituting a cup or disc, 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. Individual specification sheets, found within each product classification, outline the different types of applications, specifications and various design options.
