PTFE Lined Rubber Expansion Joint

 Rubber flexible connectors integrate the functions of expansion joints, flexible connectors and vibration isolators into one.

As expansion joints, they compensate for pipe thermal movement, eliminating the need for expansion loops which require additional material and space.

As flexible connectors, the flexibility of the EPDM carcass makes them ideal flexible connectors for handling minor misalignment and offset problems.

As flexible connectors, they protect piping system against harmful "start-up" and surge forces.

Rubber flexible connectors serve three primary functions in piping systems, to accept all directional movements, minimizing pipe stresses and compensate thermal expansion and contraction.

Rubber flexible connectors are used on both hot and chilled water circulation lines, suction and discharge sides of chiller, pumps, cooling towers, etc.

Rubber Expansion Joint has five types: single sphere rubber expansion joint, double sphere rubber expansion joint, threaded rubber expansion joint, reduced rubber expansion joint and rubber bending joint.

4)Generally speaking, there are two kinds of connections: flange and threaded. It is widely used in water supply and drainage, recycled water, air conditioning and heating, fire control, ship, water pump, and compressor, Etc. They are low cost vibration and deflection absorption in fluid conveyance pipes. The bellow consists of two symmetrical connecting end, either threaded unions for small nominal bores or flanged ends for large nominal bore pipelines. They are ideal for compensating thermal expansion and contraction in piping system as an unbeatable cost effective alternative to expansion loops which require large amounts of materials and space.
