This type of expansion joint is taken over by a bellows and two side constitute. By flexible deformation of the bellows to absorb the pipeline axial displacement (a small amount of lateral, angular displacement), the end to take over or taken over directly with the pipeline welding, or welding on a flange and pipe flange connection. The small lever on the expansion joint is a rigid support in the transport process or as a product pre-deformation adjustment is not load-bearing parts. Such expansion joint structure is simple, low cost, and thus all possible in the pipeline should be given priority to be taken into account.
