Product Description

DN40-600 Flex Expansion Joint Rubber EPDM Single Sphere Rubber Joint


Rubber 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. Expansion joint rubber is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance, The expansion joint rubber 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 expansion joint rubber


1. The expansion joint rubber has the advantages of small size, light weight, good ductility and convenient installation and maintenance.

2. Expansion joint rubber installation can cause horizontal, radial, angular offset, will not be limited by the pipe plug center, flange uneven surface.

3. When the expansion joint rubber is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

Note: 1. The special requirements of expansion joint rubber 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 expansion joint rubber can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the expansion joint rubber above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the expansion joint rubber shall be installed with anti falling device.
