Corrugated compensator

Corrugated compensators, customarily called expansion joints, or expansion joints. It consists of a bellows (an elastic element) constituting its working body and accessories such as end pipes, brackets, flanges, and ducts. It is mainly used in various pipelines. It can compensate the thermal displacement of the pipeline, mechanically deform and absorb various mechanical vibrations, and reduce the deformation stress of the pipeline and improve the service life of the pipeline. The corrugated compensator connection is divided into flange connection and welding. Direct buried pipe compensator is generally welded (except for trench installation)
