Expansion joints accommodate movement and absorb vibration in a piping system and, in doing so, they protect adjacent piping and equipment from damage. To make an expansion joint, we weld various end fittings on to a flexible bellows component. Relatively thin-walled tubing is used to form a single or multi-ply corrugated cylinder.

Expansion joints occur through all parts of a structure to provide complete separation – through floors, walls, ceilings, and roofs (interior & exterior). The size of the gap should be as small as possible to fit the design movement, and the size of the expansion joint system needs to accommodate the full range of expected movements.
