Product Details

Reinforced Flexible Double Ball Rubber Joint

Product Description

Feature :

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

Advantages: high quality rubber joint recommend quotient lead to reduce vibration noise retractility, easy to use

Application medium:Air,compressed air,water,sea water,hot water,oil,acid,alkali,etc.

Installation Instruction of Flexible Compound Rubber Joint

I. Installation over displacement limit is not allowed when installing the flexible compound rubber joint .

II. For ground-horizontally ,suspense and vertically installed rubber joints with over 1.0Mpa pressure,both sides of the pipeline shall have support or support bracket,to avoid fall or damage.

III.The force of fixing support or bracket shall be greater than the axial force of working.Otherwise the anti-fall devise is required .

IV. It shall install the GB/T9115.1(RF) standard flange(small diameter flange) when installing the corresponding flange of flexible compound rubber joints.The size of flange D2 and do shall not be too small for preventing the leakage of sealing face.

V. It shall screw down symmetrically and gradually when installing the flange screw of flexible compound rubber joint,To avoid the partly leakage or damaging the sealing face of the rubber joint.

VI. When the rubber joint is installed vertically or in suspense with over 1.0Mpa pressure ,the screw shall be installed with gasket for preventing partly leakage due to loosened screw.

VII.The flexible compound rubber joint shall have fixing support when vertical installation is made .Heavy press on the rubber joint is forbidden .
