U.S. Bellows custom designed these single expansion joints for a pipeline in China. All units are 41 3/8″ length and vary in diameter from 56.3″-76.75″. The bellows were fabricated from Incoloy 800 and the weld ends from 304H stainless steel. They are designed for an operating pressure of 15 psig at 1231°F with 2.624″ axial compression and 0.25″ lateral deflection. The bellows and weld ends were 100% radiographic tested, 100% dye-penetrant tested, and hydro-tested at 23 psig prior to shipment
