EPDM Rubber Vulcanized Double Sphere Rubber Expansion Joint

From the appearance ofdouble sphere rubber expansion joint and single ball rubber joint, its installation length is longer than that of single ball rubber joint, which solves the shortage of short installation length of rubber joint. Double sphere rubber expansion joint can be used when long rubber joint needs to be installed, but double sphere rubber expansion joint is strictly prohibited to be installed beyond the limit. The double sphere rubber expansion joint is mainly composed of the working theme rubber ball and the flange at both ends. The rubber is relatively soft, which can reduce the dynamic and noise, and can compensate the thermal expansion and cold contraction caused by the temperature change. Therefore, the double sphere rubber expansion joint is destined to play an important role in the pipeline system.

Double Sphere Rubber Expansion Joint Performance characteristics

Double sphere rubber expansion joint make use of the advantages of high elasticity, high gas, medium resistance, weather resistance and radiation resistance of rubber, which can reduce vibration and noise of pipes, and compensate for thermal expansion and cold shrinkage caused by temperature changes.

Part of double sphere rubber expansion joint technical data

Note: 1. The special requirements of double sphere rubber expansion joint can be customized according to the 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 double sphere rubber expansion joint can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. when the double sphere rubber expansion joint of DN200 and above is used for suspended water supply, the pipeline must have fixed support or fixed support, otherwise double sphere rubber expansion joint should be installed with anti falling device.
