U.S. Bellows custom-designed 23 of these tied universal expansion joints for a combined cycle power plant in Texas. This expansion joint is one of 23 units constructed and has a nominal diameter of 9′ 2″ with an overall length of 22′ 10″. The bellows are fabricated from 321 stainless steel with a carbon steel shell and tie rods. This tied joint is part of a condenser duct complex that is designed to operate at 250° F at 7.25 psig/FV, with compression of 3/16″, lateral deflection of 5 7/8″, and +/- 1.5° angulation. All expansion joints were 100% dye-penetrant tested, hydro-tested, and high vacuum (70 mbar) tested prior to shipment.
