These single externally pressurized expansion joints were custom designed by U.S. Bellows for a hot water piping system at an Air Force facility in California. All units are 4″ in diameter, with the single units having a length of 50″ face-to-face and double units having a length of 87″ face-to-face. The expansion joint’s bellows were fabricated from Inconel 625 and all other components from carbon steel. They are designed for a temperature of 400°F at 400 psig with 4″ and 8″ of axial compression. All units were hydro-tested at 600 psig prior to shipment.
