The flange loose sleeve expansion joint has the advantages of simple and reasonable structure, reliable sealing performance, no need to weld, convenient installation and disassembly. The flange loose sleeve expansion joint can compensate the displacement, dislocation and deflection of the pipeline within a certain range and has high reuse rate. Flange loose sleeve expansion joint is suitable for any medium pipeline, for valves, pumps and other equipment and pipeline connection.

      1. can realize the pipeline line axial displacement compensation.

      2. Reduce vibration and noise to a certain extent and protect the pipeline.

      3. simple structure, convenient installation, easy maintenance and maintenance.

      4. high-quality material selection is the basic guarantee of products.


      VSSJA type flange loose sleeve expansion joint install:

      After the flange type loose sleeve expansion joint is installed on the pipe, tighten the elastic sealing ring of the nut. Under the action of the nut gland, the sealing and connecting function of the outer ring of the pipe is tightly pressed depending on the mutual inclination. When the temperature changes, the pipe can be freely expanded in the middle of the joint, when the foundation sinks, the pipe can be deflected, and ensure that the seal does not leak, so as to play the purpose of automatic compensation.
