Rubber flexible joint refers to that on the basis of rubber flexible joint, polyethylene tetrafluoroethylene material is added into the rubber flexible joint through processing, which can play a special role in acid and alkali resistance, corrosion resistance, high temperature resistance, wear resistance and other special properties. The rubber joint is made of polyester cord fabric and then vulcanized by high temperature, high pressure and other molds. By processing a special layer of fluoroplastic PTFE material in the ball, and then processing it under strong corrosion conditions, the tetrafluororubber soft joint adopts a special process.  Lined with four flourine joint flexible joint means that the outer wall is a black sphere, two flanges are installed at both ends of the sphere, the flange materials are carbon steel and stainless steel, and the rubber flexible joint is lined with white lined with four flourine joint.

The bellows expansion joint is composed of a bellows and two end pipes. The end pipe is either directly welded to the pipe, or welded to the flange and then connected to the pipe flange. Has the ability to absorb the thermal expansion of the pipeline.
The compensator is a compensation element, effective use of bellows telescopic body deformation, dimensional change in absorption pipeline, pipe, thermal expansion and contraction caused by the container, or compensation pipeline, conduit, vessel axial, transverse and angular displacement. Ripple compensator is mainly used for noise reduction and vibration reduction. It is widely used in modern industry.
