24" Dia. Universal Expansion Joint Designed for a Refinery in Europe

U.S. Bellows designed and manufactured this universal expansion joint in accordance with ASME section VIII for an oil and gas refinery in Europe. A U2A- form was furnished as part of the units’ documentation. The expansion joint has a 24″ diameter and 103″ overall length. The bellows, liners and covers are fabricated from 316 stainless steel, and the flanges, tie-rods and pipe are carbon steel. The unit is designed for an operating temperature of 181°F at 101 psig and 1″ axial movement with a 3″ lateral offset. The bellows and pipe longitudinal weld seams were x-rayed, dye-penetrant and hydro- tested prior to shipment.

12" Universal Expansion Joints

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.

163" O.A.L Expansion Joint Designed for the Reactor Stand Pipe

U.S. Bellows, Inc. specially designed and manufactured two 55″ O.D. refractory lined universal gimbal expansion joints for a refinery in Joliet. These expansion joints are equipped with slotted hinges with an overall length of 163″ and 286″ respectively.  The 163″ O.A.L. expansion joint, designed for 60 PSIG and 1020°F, will be used at the reactor stand pipe of the refinery. The 286″ O.A.L. expansion joint will be used for the regenerator stand pipe of the refinery and it is designed for 57 PSIG and 1300°F. Both expansion joints consist of a A516 Gr70 pipe, two SB-443 two-ply bellows and a slotted hinge.

To ensure quality, 100% dye-penetration, 100% x-ray and pressure tests were performed on the bellows. Pneumatic and vacuum tests were also conducted on the expansion joints and between bellows dry plies prior to shipping.
