The existing metal corrugated compensator is composed of a corrugated pipe (an elastic element) forming a working main body of the compensator, an end pipe, a support, a flange, a guide pipe and other accessories, and belongs to a compensating element. The effective telescopic deformation of the working body corrugated pipe is utilized to absorb the dimensional change of pipelines, conduits, containers and the like caused by expansion and contraction due to heat and the like or compensate the axial, transverse and angular displacement of the pipelines, the conduits, the containers and the like. And can also be used for noise reduction and vibration reduction. Has wide application in modern industry. In order to prevent the pipeline from deforming or breaking due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator is required to be arranged on the pipeline to compensate the thermal elongation of the pipeline, so that the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure are reduced.
