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.
Range of use
Based on the excellent overall performance, the flexible rubber expansion joint is widely used in 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.
