September 29, 2015

10" Dia. Universal Expansion Joints for HVAC Service in California
US 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.
