U.S. Bellows refurbished this double gimbal expansion joint for an oil refinery in Baytown, Texas. The bellows were replaced with Inconel 625 and the duct, elbow, cover, and liner are carbon steel. This unit has a diameter of 20″ and an overall length of 108″. The expansion joint was designed for 4″ lateral movement at 450°F and 180 psig. Prior to shipment, the unit was 100% dye penetrant tested, PMI examined, and hydrotested.
