[0002] Bellow compensator, also called expansion joint or expansion coupling, is composed of bellow (a kind of elastic element) which constitutes its working main body and end pipe, support, flange, conduit and other accessories. It is mainly used in various pipelines, which can compensate thermal displacement of pipeline, mechanical deformation and absorb various mechanical vibrations, and plays a role in reducing pipeline deformation stress and improving service life of pipeline.

[0003] The existing bellow compensator has general heat dissipation performance, and overheat is prone to occur when the liquid is relatively hot, resulting in reduced service life. In addition, the existing bellow compensator has poor buffering performance. Since instantaneous pressure impact or fluctuation may occur in the pipeline system, such as sudden start-stop of fluid, water hammer phenomenon, etc., long-term impact is easy to cause reduction of service life of bellow compensator. Therefore, in view of the above status, it is urgent to develop a high-temperature-resistant bellow compensator with good heat dissipation, high-temperature-resistant use, good buffering performance and longer service life to overcome the deficiencies in current actual application and meet the current demand.
