U.S. Bellows, Inc. designed and fabricated 36″ pressure balanced elbow expansion joints that weigh approximately 4,300 lb. each. The pressure-balanced design does not exert pressure thrust on the equipment in the piping system. The expansion joints are designed with Inconel® 625 grade LCF bellows and include a liner provided with drain holes to prevent the accumulation of corrosive condensation. The design movements are 1/2″ axial compression and 3/4″ lateral movement. The bellows were 100% x-rayed before forming and dye-penetrant examined after forming.
