Rubber expansion joints consist of inner and outer rubber, nylon cord fabric which are vulcanized and then combined with metal flanges or loose sleeves of parallel joints.
This product can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems.
The rubber expansion joints allow for four way movements, and they are precision molded from synthetic rubber and nylon cord, and this can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change.
Bellow expansion joint is the most common and popular, it is mainly used in pipe connection, absorb the extension and compression of pipe, according to different working situation, we usually recommend different structure.


Rubber expansion joints consist of inner and outer rubber, nylon cord fabric which are vulcanized and then combined with metal flanges or loose sleeves of parallel joints.
This product can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems1. The product could primarily reduce the quiver and noise of the piping system; completely solve the different piping problems as displacement of joint, axial flex and etc.
2. According to different material requirement, product could be made as acid proof, alkali proof, corrosion proof to suit different medium and environment.
3. The material are good sealing, light weighting, easy to fix and maintain, also has long usage life, But please keep far away from sharp metal in order to avoid breaking of the ball.
4. Overhead use should match with the resilience supporting, and diagonally method should be used when fit the bonnet.
5. Please use limiting bonnet to connect the flanges if piping pressure is high.
