These universal metallic expansion joints were custom designed for a chemical plant in Texas. They are fabricated entirely from stainless steel with 304 stainless steel bellows. The expansion joints are 12″ diameter, 77-1/2″ long and designed for 4-1/2″ axial movement and 2″ lateral movement. They were designed for 200°F and 100 psig. Each unit was 100% dye penetrant examined and hydrotested prior to shipment.

U.S. Bellows designed and fabricated tied universal expansion joints and single hinged expansion joints for a power plant in Canada. All the units were fabricated from carbon steel with 316 stainless steel bellows. The universal tied joints are 102″ diameter, 225″ long and are designed for 8.2″ lateral movement. The hinged joints are 102″ diameter, 71″ long and designed for 0.76° angular rotation. Each expansion joint can withstand temperatures up to 250°F at 7.25 psig. The bellows and pipe long seams were 100% x-rayed, and all the welds were 100% dye penetrant tested. A soap and air test were performed prior to shipment.
