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.
