Bellows or EXPANSION JOINT are connections that are designed to safely absorb the dimensional changes of the piping system. These changes occur due to expansion and contraction caused by heat, vibrations caused by the rotation of machines, changes in pressure and other factors. Accordions are made of different materials such as metal, plastic and fabric.
