These fabric expansion joints were fabricated from stainless steel pipe and flanges with a three layer fabric belt protected by an insulation pillow. Each joint is 44″ ID x 40″ face-to-face and designed for 3 PSIG at 845°F. The expansion joints are designed for a lateral movement of 1/2″ and an angular rotation of 1.5°. Stainless steel covers were included to protect the fabric expansion element from possible outside damage.
US Bellows fabricated rectangular fabric expansion joints for a gas turbine. They are 136″ L x 54″ W 12″ face-to-face. The frame and liner are fabricated from stainless steel and the fabric belt is 1-ply PTFE. The expansion joints are designed for 600°F at +/- 100″ water column. A 100% dye-penetrant examination was performed prior to shipment.
U.S. Bellows custom-designed inline pressure balanced expansion joints for a pipeline in Texas. The bellows are fabricated from 316 stainless steel and the flanges and liners from carbon steel. The units have a 20″ diameter and are 30″ in overall length. The expansion joints were designed for 0.17″ compression with an operating temperature of 150°F at 285 psig. A dye penetrant test and pressure test at 300 PSIG was performed prior to shipment.

US Bellows custom-designed this tied universal expansion joint for a power plant. The expansion joint is 12″ Dia. x 34 1/2″ OAL. The bellows are fabricated from Inconel 625 LCF and the tie rod ring attachments, pipe and tie rods are 316 stainless steel. It is designed for an axial movement of 1/2″, a lateral movement of 2 1/4″ at 1250°F and 120 PSIG. The bellows longitudinal seam was 100% x-rayed, all welds were dye penetrant-examined and the unit hydrotested prior to shipment.
U.S. Bellows, Inc. fabricated this 84″ diameter universal expansion joint with refractory lining for an FCC unit in Texas. The unit is designed with 321 stainless steel bellows and carbon steel flanges. It is lined with a 4″ thick refractory lining and measures 96″ in overall length. The bellows long seams were 100% x-rayed and dye-penetrant tested
US 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.
US Bellows custom-designed this single externally pressurized expansion joint for an oil refinery in Saudi Arabia. The bellows are fabricated completely from 316 stainless steel. The expansion joint is 32″ in diameter and 61-1/4″ in length. It is designed for 8″ axial movement and 150 psig at 176°F, with a spring rate of 1096 lb./in. The unit had the stainless steel alloy material PMI examined. It was also dyed penetrant examined and hydro tested prior to shipment.
