Flanged Connector PN16 EPDM Expansion Joint Flexible Rubber Compensator
EPDM expansion joint can also be called: expansion joint rubber, rubber flexible joint, soft joint, flexible rubber joint, rubber expansion joint, shock absorption throat, shock absorber, etc. EPDM expansion joint is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance, The EPDM expansion joint is usually made of inner rubber layer, which can reduce the vibration and noise of the pipeline and compensate the thermal expansion and cold contraction caused by the temperature change.
Performance characteristics of EPDM expansion joint
1. The EPDM expansion joint has the advantages of small volume, light weight, good elasticity and convenient installation and maintenance.
2. After installation, the EPDM expansion joint can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline, and is not limited by the non concentric pipeline and non parallel flange.
3. After the EPDM expansion joint is installed, the noise caused by the vibration of the pipeline water pump can be reduced, and the vibration absorption ability is strong.
4. The inner seamless high pressure EPDM expansion joint can effectively prevent the corrosive medium from eroding the inner wall of the rubber joint in the high temperature resistant, acid alkali resistant and oil resistant pipeline, and improve the service life.

Note: 1. The special requirements of EPDM expansion joint can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of EPDM expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the EPDM expansion joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the EPDM expansion joint shall be installed with anti falling device.
