Product Introduction
Reducer rubber expansion joint is similar to the concentric reducer rubber joint, it’s also often used to connect the pipes with different diameters, in order to facilitate the connecting of pipes.
Solve the connection problem of plumbing system with different diameter.
Solve the problem of interface displacement, absorb the pipe movement, improve thermal stability.
Rubber expansion joint can reduce the noise and improve the shock absorption ability.
Product Features
Yifa Reducer Rubber Expansion Joint has futures as below:
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 yifa 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.
