Product advantage：

Flange type loose sleeve expansion joint is suitable for valves and other equipment and pipe connection, flange loose sleeve expansion joint at the same time can compensate the pipeline axial displacement and a certain amount of deflection and eccentricity, so as to protect valves and other equipment. The socket is also suitable for connecting with steel pipe, cast iron pipe, ductile iron pipe, PVC pipe, ABS pipe, etc. The VSSJA(AF) flanged loose sleeve expansion joint can cause the deformation of the sealing ring through the mutual extrusion of the gland and the body, so as to realize the compensation of the axial displacement of the pipeline and ensure the high sealing of the pipeline line. And because it adopts flexible connection, it can greatly reduce the impact of vibration and noise of pipeline lines. Ensure the smooth operation of the pipeline.

product feature：

The flange type loose sleeve expansion joint is designed by our company at the same time by absorbing the advantages of similar products at home and abroad. 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.
