[0002] The bellows compensator belongs to a compensation element, generally called an expansion joint or a telescopic joint. By using the effective telescopic deformation of its working main body bellows, it can absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, etc., or compensate for the axial, lateral and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. The bellows compensator is composed of a bellows (an elastic element) that constitutes its working main body and accessories such as tie rods, brackets, flanges, and conduits. It is mainly used in various pipelines. It can compensate for the thermal displacement and mechanical deformation of the pipeline and absorb various mechanical vibrations, playing the role of reducing the pipeline deformation stress and increasing the service life of the pipeline. The connection methods of the bellows compensator are divided into two types: flange connection and welding. The direct-buried pipeline compensator generally adopts the welding method. The bellows compensator is a compensation device that uses the effective telescopic deformation of the elastic element of the bellows compensator to absorb the dimensional changes of pipelines, conduits or containers caused by thermal expansion and contraction, etc. It belongs to a compensation element. It can absorb axial, lateral and angular displacements.
