US 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. US Bellows completed this expansion joint project ahead of schedule
