60" Dia. Elbow Pressure Balanced Expansion Joint Refurbished in 3 Weeks for a Power Generation Plant

This 60″ dia. x 20′ OAL elbow pressure balanced expansion joint was refurbished by U.S. Bellows in 3 weeks for a power generation plant in Wisconsin. The bellows are fabricated from Inconel 625 and the duct, elbow, cover and liner of carbon steel. The expansion joint was designed for 1″ axial movement at 715°F and 185 psig. The bellows longitudinal seams were 100% x-rayed prior to forming. After replacing the bellows, the expansion joint was dye penetrant tested and hydro tested at 185 psig.
