Metal Expansion Joints is one of the products in pipeline installation. It works by using the scalability of metal bellows to reduce the problems caused by thermal expansion and contraction of pipes. Compensation effect has pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction, to reduce the deformation of the pipeline and improve the service life of the pipeline effect. We produce both pipe metal expansion joint and rectangular metal expansion joint. The specific products are sleeve type expansion joint, axial corrugated compensator, joint metal compensator etc.
