U.S. Bellows offers all types of metallic 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 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.

Slip-type Expansion Joint for Hydrocarbon Flaring System
The photographs above show a special slip type expansion joint designed by the Sweco Fab Division of Piping Technology & Products, Inc. for installation in the hydrocarbon flaring system of a combination of design features and material specifications. At the top right of the picture is the inner barrel which is uniquely plated to be corrosion resistant. At the bottom right of the picture is the aluminum bronze bearing sleeve which provides strength and guidance for the inner barrel. At the left is the assembled unit shows the outer barrel which contains the six packing seals, the follower and the retaining ring. This joint is to be installed in a horizontal position in the mid span of 40 feet between guided supports. The design conditions are 12” of movements, 650oF, and 50 PSI of internal pressure.
