EPDM NBR Reduced Rubber Expansion Joint Shock Absorption
Rubber Expansion Joint s are also called rubber joints, rubber flexible joints, soft joints, shock absorbers, pipeline shock absorbers, shock-absorbing throats, etc. They are a kind of high elasticity, high air tightness, medium resistance and weather resistance. Pipe joints. This product takes advantage of rubber's elasticity, high air tightness, medium resistance
Features
1.Small volume,light flexible ,easy to install and maintain
2.It reduces structural noise transmission with strong shock absorption in servive.
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 .
