Read MoreU.S. Bellows designed this hinged expansion joint for a pipeline in Mexico. It is 30″ in diameter and 18″ in length. The bellows are fabricated from 304 stainless steel, and the remainder of the assembly is carbon steel. The expansion joint is designed for an operating pressure of 25 psig at 986°F, with an angular movement of 4.5°. All units in this project were 100% dye-penetrant and hydro-tested prior to shipment.
US Bellows designed these EPDM neoprene fabric expansion joints for a generator fan application at a gas turbine facility. The expansion joints are 54″ in diameter and 15″ OAL. Each unit was fabricated has an EPDM fabric belt, stainless steel band clamps, and carbon steel angle flanged ends. The expansion joints are designed for -20°F/+200°F at +/- 100″ water column. A 100% dye penetrant examination on all carbon steel welds was conducted on all units prior to shipment.

US Bellows designed this tied universal elbow expansion joint for a chemical plant in Arkansas. The bellows, pipe, and liner were made from 304 stainless steel and the tie rods and cover from carbon steel. The expansion joint is 30″ in diameter and 134″ center line to center line of the elbow. It is designed for an operating temperature of 450°F at 200 psig and 2″ of axial lateral. All butt welds were 100% x-rayed and the remaining welds were dye penetrant examined. The complete unit was hydrotested prior to shipment.
These neoprene expansion joints were designed for a gas turbine application. Each expansion joint is 42″ ID and 7″ OAL. The frame was fabricated from A572 Gr.50 carbon steel, the clamps from 304 stainless steel, and the belt is reinforced neoprene. The expansion joints were designed for -20°F/+200°F with a +/- 100″ water column. A dye penetrant examination on the welds was performed prior to shipment.

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.
These tied universal expansion joints were custom designed by U.S. Bellows for a pipeline in Connecticut. All components of the expansion joints were fabricated from 316 stainless steel. The job was comprised of units that were 12″ or 16″ in diameter and 60″ in OAL. They are designed for an operating pressure of 10-125 psig at 450°F and a lateral movement of +/- 1″. All of the expansion joints were 100% dye-penetrant tested and hydro-tested at 150 and 175 psig prior to shipment.

US Bellows designed these universal expansion joints with flanges for HVAC services in California. The bellows are fabricated from 304 stainless steel, the flanges from A105 carbon steel, and pipe from 106 Gr. B carbon steel. The expansion joints in this project ranged from 3″ to 10″ in diameter, and are designed for an operating temperature of 160°F to 353°F at 120-125 PSIG, with an axial compression of 1.5″ and a lateral deflection of 1.3″. All expansion joints were 100% dye-penetrant tested and hydro-tested prior to shipment.
| Type: | Single Expansion Joint |
| Size: | 18″ Diameter and 120″ OAL |
| Material: | 316 Stainless Steel |
| Design | 35 PSIG at an Operating Temperature 1200°F |
