U.S. Bellows designed this hinged expansion joint for a pipeline in Mexico. It is 30″ in diameter and 18″ in length. The bellows are fabricated from 304 stainless steel, and the remainder of the assembly is carbon steel. The expansion joint is designed for an operating pressure of 25 psig at 986°F, with an angular movement of 4.5°. All units in this project were 100% dye-penetrant and hydro-tested prior to shipment.
