36" Pressure Balanced Elbow Expansion Joints
May 30th, 2007
U.S. Bellows, Inc. designed and fabricated 36″ pressure balanced elbow expansion joints that weigh approximately 4,300 lbs each. The pressure balanced design does not exert pressure thrust on the equipment in the piping system.
The expansion joints are designed with InconelĀ® 625 grade LCF bellows and include a liner provided with drain holes to prevent 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.
