The U-66 is constructed of high-grade abrasion and chemical resistant solid-cast polyurethane material. Inflatable type has hollow core with inflation device, which can be filled with liquid and pressurized up to 2% of standard diameter for proper fit in pipeline. 2” through 6” are available in solid type only, and 4” through 48” are available in inflatable type. The U-66 is used in harsher sphere applications. The construction material is more rugged, minimizing blistering and molecular deterioration. Options include neoprene, viton, epdm, buna-n or other elastomer compounds for special services; varying durometers (hardness); sphere-filling pump and accessories; customized sizing for special pigging applications.
