U.S. Bellows designed these single gimbal expansion joints with floating ring gimbal attachment to the pipe for a flare gas and steam application at a methanol plant in Texas. The bellows were fabricated from Inconel® 625 LCF, the liner and the weld-ends from 316H stainless steel, the cover from 304 stainless steel, and the gimbal structure from A516 carbon steel. The expansion joints are 48″ diameter and are 61 3/8″ in overall length, and are designed for an operating temperature of 752°F at 50 psig. All expansion joints were 100% dye penetrant, X-ray, and hydrotested prior to shipment.
