Feature of Flexible Rubber Expansion Joints:
1.Small volume, light flexible ,easy to install and maintain
2.It reduces structural noise transmission with strong shock absorption in service.
3.It is capable of horizontal, axial and angular displacement with the restruction and flange non-parallelism.
4.The inner seamless high-pressure rubber joint independently developed by us prevents corrosive medium from etching the inner wall of the rubber joint in high temperature ,acid and alkali and oil resistant pipeline, thereby extending its service life .
Purpose: and pump valve connection fire fighting equipment, vibration large pipe cold and hot change frequent pipeline
Advantages: high quality rubber joint recommend quotient lead to reduce vibration noise retractility, easy to use
