Sale worldwide reducer rubber expansion joint with flange connection
Introduction of reducer type rubber expansion joint:
The utility model relates to a flexible eccentric eccentric rubber joint, which can solve the problem of different caliber when the metal pipe is connected,and has the function of shock absorption and noise reduction, and can save the installation parts of the pipeline and save the cost. The utility model is composed of an inner rubber layer, a fabric reinforcing layer, a middle rubber layer, an outer rubber layer, an end reinforcement, a metal ring or a steel wire ring, a metal flange or a parallel movable joint.
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 .
