U.S. Bellows designed these universal expansion joints with flanges for HVAC services in California. The bellows are fabricated from 304 stainless steel, the flanges from A105 carbon steel, and pipe from 106 Gr. B carbon steel. The expansion joints in this project ranged from 3″ to 10″ in diameter, and are designed for an operating temperature of 160°F to 353°F at 120-125 psig, with an axial compression of 1.5″ and a lateral deflection of 1.3″. All expansion joints were 100% dye-penetrant tested and hydro-tested prior to shipment.

U.S. Bellows designed this universal expansion joint for a thermal power plant in Oregon. The expansion joint is 136″ in diameter and 36″ in OAL. The bellows are fabricated from stainless steel and the flanges and pipe are carbon steel. It is designed for a lateral movement of 1/2″ at 250°F and 15 psig. The expansion joint was 100% dye-penetrant tested prior to shipment.

U.S. Bellows designed these universal expansion joints with limit rods for a pipeline in Taiwan. The expansion joints are 4″ diameter by 18″ length. The bellows are fabricated from 304 stainless steel and the flanges are 316 stainless steel. They are designed for an operating temperature of 150°F at 150 psig, with a compression of 1.5″ and a lateral deflection of 0.5″. All expansion joints were 100% dye-penetrant tested and hydro-tested prior to shipment.
