Single Hinged Expansion Joint Refurbished in Two Weeks

Within a two week deadline, U.S. Bellows refurbished a 59-1/4″ diameter single hinged expansion joint for a refinery in Louisiana. The expansion joint is 119-3/4″ in overall length and designed for .82″ angular rotation at 1380°F and 35 psig. The bellows are fabricated from Inconel 625 LCF, and the entire assembly is 304H stainless steel. Before shipment, the bellows were x-rayed and the assembly was 100% dye penetrant and air tested to 52 psig.

Each type has advantages and limitations that can provide flexibility, load reduction, structural integrity and reliability required in a piping system.
Metal expansion joints can withstand the design temperatures and pressures, as well as provide the capacity necessary to absorb thermal growth of the piping system. The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of an expansion joint must be restrained by the use of tie rods, hinges or a gimbal while allowing the bellows to move through its design deflections.

Elbow Pressure Balanced Expansion Joint Designed for an Exhaust Duct

U.S. Bellows designed and manufactured a 64” diameter custom elbow pressure balanced expansion joint for an exhaust duct in a power plant in Alberta, Canada. It is 386” in overall length and is fabricated from carbon steel with 321 stainless steel bellows. This expansion joint is designed for 1-1/8” axial movement, ½” lateral movement at 482°F and 174 psig. Tests performed on the unit include 100% dye penetrant, x-ray, and ultrasonic on pressure bearing welds. The unit was also hydrotested at 291 psig prior to shipment.

Single Expansion Joints Designed for Gas Service in Peru

These single expansion joints are 20″ in overall length and range in diameter from 3″ to 56″. They are composed of 321 stainless steel bellows, 316L flanges and angles, and include carbon steel covers. The expansion joints were designed for 194°F at 22 PSIG and were dye penetrant examined and soap and air tested prior to shipping to Peru.
