Urethane SpheresU-53 Polyurethane Sphere; U-58 Polyurethane Sphere; U-66 Polyurethane Sphere
ThePolyurethane Spheres Spheres are primarily used for meter proving in the oil and gas industry, but can also be used for hydrostatic testing, batching, and product removal. The unique aspect with spheres is their ability to negotiate tight-radius bends and magazine loading in specially designed sphere launchers for automated mechanical launching. Depending on the size, they are available in solid and inflatable type designs.
U-53 Polyurethane Sphere
The U-53 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 4” are available in solid type only, and 6” through 48” are available in inflatable type. The U-53 is primarily used as a meter prover sphere in sweet crude oil, heating oils, gasolines, jet fuels, natural gas liquids, butanes and propanes as well as other refined products that are not aromatics. Options include 53, 58, and 66 durometers (polyurethane) in yellow, green and red color, 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.
