Expansion Bellows is the simplest and most widely used assembly in family of Expansion Joints & Bellows. It is least expensive types of Bellows and can absorb all types of movement axial, lateral and angular movements in pipe configuration along the axis of pipeline. This Expansion Bellows should not be expected to control the movement of the pipe. In case the piping analysis indicates that expansion joints must accept axial compression the piping must be guided and constrained so that only the movement will occur.
