The photographs above show a double hinged expansion joint (figure 1) and a double gimbal expansion joint (figure 2) for a gas application at a project in Mexico. These uniquely designed expansion joints, bellows, flanges and pipes are fabricated from Inco. 800 H and designed at 60 psig and 1050oF. These expansion joints were 100 percent x-rayed and hydro-tested.

U.S. Bellows, Inc. custom designed and manufactured three 2’ – 6” OD x 23’ – 1/3” long expansion joints for a refinery in New Jersey. The bellows, pipes, and lugs were fabricated from Inco 800H high nickel alloy, A312tp 316H stainless steel, and A240tp 316H stainless steel respectively. The expansion joints are designed for 60 PSIG, 1100°F, and 47,000 lbs. of thrust to accommodate for a high temperature application.To ensure quality, the bellows and pipe-long seam welds were 100% x-rayed. In addition, hydro-testing was conducted at 90 PSIG and all construction materials are PMI before and after assembly.

U.S. Bellows, Inc. designed and fabricated this expansion joint exhaust assembly for an oil refinery in Texas. This expansion joint is offset for an offshore platform and weighs approximately 8,000 lbs. It has a design pressure and temperature of 1 PSIG and 1000 degrees, respectively. The air test was conducted to detect any leaks.

The 24” diameter hinged expansion joint shown above was designed to absorb lateral deflection and limited angular rotation in one plane only. They were supplied by U.S. Bellows, Inc. for an emergency shut down delivery requirement.
