U.S. Bellows, Inc. specially designed and manufactured a double hinged refractory lined expansion joint for a chemical refinery in Michigan. This expansion joint with an overall length of 40′-0″ has a 4″ thick refractory lining installed per UOP specifications. It also consists of testable two plies SB-443/Inco 625LCF bellows, 5/8″ thick, A516-70 mitered elbows, 5/8″ thick, A516-70 spool, A240-304 liners, A516-70 hinges, A193, GR 7 tie rods, and A516-70 lugs.

This expansion joint is designed for 50 PSIG and 1440°F with 3″ of lateral movement per B31.3 and EJMA standards. To ensure quality, 100% X-Ray and 100% dye-penetration tests were performed on the bellows after forming. A pneumatic test at 75 PSIG was conducted on the expansion joint assembly prior to shipping.
