Metallic Expansion Joints

U.S. Bellows offers all types of metal expansion joints. 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, 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 gimbal while allowing the bellows to move through its design deflections.
