Features
1. The flexible rubber expansion joint is of small volume, light weight, good flexibility and convenient installation and maintenance ;
2. The flexible rubber expansion joint has transverse displacement, axial displacement and angular displacement and not restricted by inconsistent pipeline and unparallel flange in installation;
3. The flexible rubber expansion joint reduces vibration and noise;
4. The flexible rubber expansion joint with seamless inside and resistance to high temperature which is developed by our company can prevent the corrosive medium from corroding the inner wall more efficiently in the pipeline of high temperature resistance, acid and alkali resistance and oil resistance.
Based on its excellent overall performance, the flexible rubber expansion joint is widely used in the chemical industry, construction, drainage, oil industry, light and heavy industry, refrigeration industry, sanitary system, plumbing system, firefighting, and power electrics, such as the connection with pump or valve and pipeline with vibration or large temperature changes.
