U.S. Bellows custom designed five of these 178″ tied universal expansion joints for an exhaust duct application in a power plant in Virginia. The expansion joints are 178″ in diameter and 276″ in length. The bellows were fabricated from 321 stainless steel and the rest of the assembly from carbon steel. They are designed for an operating temperature of 248°F at 22.5 psig, an operating load of 1256 lb/in, and 6.25″ of lateral deflection. All units were 100% dye-penetrant and soap and air tested prior to shipment. Because of the sheer size of the units, all of the tie rod supports were FEA analyzed.
