U.S. Bellows designed and fabricated several single and universal expansion joints for a 12″ pipe size. The single joint has an axial movement of 1 3/8″ and the universal joint has a 2 1/2″ lateral movement. The design pressure is 276 PSIG and the design temperature is 626°F.
Both single and universal expansion joints have 316L SS bellows, flanges and tie rods. These expansion joints have 300 pound raised face stainless steel flanges and are designed to accommodate the customers’ low spring rate requirements. Each expansion joint was 100% dye-penetrant tested and hydro-tested at 414 PSIG. U.S. Bellows completed this expansion joint project ahead of schedule
