Description

Rubber Expansion Joint Coupling also known as shock absorber, pipeline shock absorber, rubber shock absorber, soft joint, is the flexible connection of metal pipeline, by the inner rubber layer, nylon cord fabric enhancement, outer rubber layer composite rubber ball and loose metal flange. Rubber Expansion Joint Coupling is characterized by high pressure resistance, good elasticity, large displacement, balance pipe deviation, absorption of vibration, good noise reduction and easy installation.Rubber Expansion Joint Coupling widely used in chemical, construction, water supply, drainage, petroleum, light heavy industry, refrigeration, sanitation, water heating, fire protection and other basic projects.

1. Rubber Expansion Joint Coupling are low cost vibration and deflection absorption components in fluid conveyance pipelines.

2. The bellows consists of two symmetrical connecting ends, either threaded unions for smaller nominal bores or flanged ends for larger nominal bore pipelines.

3. The body of the bellows is essentially a robust rubber cylinder that is capable of absorbing vibration and movement in pipeline components.

4. Bellows are often installed in-line with water pumps as the absorber of the operating vibration of the pump and movements due to pump start up, shut down.

5. Bellows are also able to absorb axial displacement due to pipeline expansion and contraction, and lateral displacement and pipeline angularity.
