These inline pressure balanced expansion joints were custom designed by U.S. Bellows for a wastewater treatment plant in California. The units are 12″ in diameter and 32″ in overall length. All components of the expansion joints (bellows, covers, liners, rings, and flanges) were completely fabricated from 304 stainless steel. They are designed for an operating temperature 200° at 55 psig, with 7/8″ of axial compression and .07″ of lateral movement. All units were 100% dye-penetrant, PMI, X-Ray, and hydro-tested prior to shipment.
