Rubber expansion joints consist of inner and outer rubber, cord layer and traveler, 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.
Features
1. The flexible rubber expansion joints are easy to be installed and maintained.
2. The flexible rubber expansion joints have good flexibility, allow transverse, axial and angular displacement.
3. The flexible rubber expansion joints can reduce vibration and noise.
4. The flexible rubber expansion joints can bear high temperature, corrosive medium.
