Flexible Rubber Expansion Joints DN250 Pn10 Epdm Rubber Coupling Joint
Product introduction
Rubber expansion joint is a flexible connector fabricated of natural and/or synthetic elastomers and fabric, if necessary, internal metallic reinforcements designed to provide stress relief in piping systems due to thermal movements and mechanical vibration.
There are lots of material selection based on usage area of rubber expansion joints. Rubber expansion joints can absorb large movement in very short distance. They provide all directional movement, such as axial, angular, lateral and torsional that may occur from external conditions. Also reduce wind, shock loading and seismic movements.
Advantages of rubber expansion joints
1. Rubber expansion joints provide excellent compensating features by their highly rated rubber bellows to compensate thermal expansion and compression.
2. They may be produced with flange and threaded connections.
3. They may have two bellowed structure in order to absorb large movements.
4. Rubber expansion joints are designed to compensate axial, lateral, angular and transverse movements at the same time.
5. Reduce tension in the pipelines.
6. Prevent noise and vibration to protect the connected systems.
7. Compensate for ground, and settlement of especially the new buildings.
8. Provide proper sealing with their elastic structures where the pipelines pass through walls.
Functions
The functions of rubber expansion joints:
1. Allow moving to the four directions.
2. Reducing the vibration and noise.
3. Resistant of the high pressure and corrosion.
4. Wear resistant, waterproof, oil resistant, acid resistant, alkali resistant.
5. Easy to install with the flexible flange.
