Metallic Expansion Joints

U.S. Bellows/PT&P offers all types of metal expansion joints.  Each type has advantages and limitations, which when applied correctly, can provide the flexibility, load reduction, structural integrity and reliability desired in a piping system.

Metal expansion joints, besides acting as sections of a pipe, capable of withstanding the design temperatures, pressures, and media, also provide the flexibility that makes them necessary. That flexibility can be either axial, lateral or angular. However, in many installations, some rigidity or structural strength is needed to support piping loads or to control the motion of the bellows and the pipe. Features are then added to the expansion joint to limit the modes or degrees of freedom, or the types of deflections, and to resist shear, or tension, or compression loads and/or bending moments.
