U.S. Bellows/PT&P Manufactures 36" Gimbal Expansion joints for Petrochemical Company in California -- 08/04/99 

In 1999, U.S. Bellows, Inc., fabricated three 36" diameter single gimbal expansion joints for a large petrochemical company in California. These expansion joints are designed for 750 PSIG and 275° F. The design pressure thrust is approximately 1,000,000 lbs and the hydro-test pressure thrust is approximately 1,500,000 lbs. Fabricated from Inconel 625 material, these expansion joints are equipped with testing ports to detect leakage in between the two plies. The gimbal ring, hinges, standoff, and pins have all been designed to withstand the design and hydro-test pressure thrust force. The total assembled weight of each expansion joint is 14,560 lbs. Gimbal expansion joints allow for restrained angular movement of attached piping in two planes. Expansion joints, in general, allow for axial, lateral, angular and torsional movement in piping systems.
