U.S. Bellows, Inc., a subsidiary of PT&P, has recently supplied four 72-inch expansion joints required for the piping system of a power plant being built in Zhuhai, China. These large expansion joints will carry the exhaust from the plant’s boiler feed pump turbines.
72" Dia. Universal Expansion Joint
This critical piping application often requires pressure-balanced expansion joints, but in this case a unique combination of a universal joint in one plane (left side of photo) and a hinged joint (right side of photo) was used.
5’ x 22’ Thick-wall Tied Universal Expansion Joint
Piping Technology & Products, Inc. engineered, designed and built this 5’ x 22’ stainless steel, thick wall, tied, universal expansion joint for a major producer of agricultural chemicals in Louisiana. A special in-house CAD program was utilized in the design effort for these expansion bellows to meet the process parameters. Also, special guides and anchors were provided to facilitate proper operation of this critical unit within the system.
