Background

Expansion joints are also conventionally called compensators, or expansion joints. It is composed of bellows (an elastic element) and its working body, end pipe, support, flange and guide pipe. The expansion joint is a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses due to temperature differences and mechanical vibrations. 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. 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.
