These tied universal expansion joints were custom designed by U.S. Bellows for a pipeline in Connecticut. All components of the expansion joints were fabricated from 316 stainless steel. The job was comprised of units that were 12″ or 16″ in diameter and 60″ in OAL. They are designed for an operating pressure of 10-125 psig at 450°F and a lateral movement of +/- 1″. All of the expansion joints were 100% dye-penetrant tested and hydro-tested at 150 and 175 psig prior to shipment.
