GJQ(X)-DF-I Floating Flange Single Sphere Rubber Expansion Joint
Rubber expansion joints can be used for the upgrading and transportation of raw water and sewage, thermal power plant water supply and cooling circulating water, metallurgy, condensate, chemical pipeline transportation in the chemical industry, cooling in the petrochemical industry, dilution and flexibility between long and short pipelines in other industries connection. It is also suitable for the low temperature transport of granular, powdery and vaporous bodies in related industries.
Single sphere rubber expansion joint mainly utilizes the unique properties of rubber, such as high elasticity, high air tightness, medium resistance and radiation resistance. It is made of high-strength, cold-heat-stabilized polyester cord obliquely mixed with rubber, after high pressure and high temperature. Vulcanized gas in the mould, rubber expansion joints become high internal density, can withstand higher pressure, good elastic deformation effect. high radian arch, long curve makes large multi-displacement function, and especially for some places where is complex geological condition, large settlement, and frequently changed pipeline which is likely to cause damage in holt and cold, the flexible displacement of the rubber and the heat transfer function of the deformed mechanical force can effectively eliminate the physical damage of the displacement of the pump, the valve and the pipeline itself. Because rubber is a poor conductive material, it is a good product to reduce vibration and noise transmission. The design of rubber expansion joint is smooth inside the wall, after actual testing, it has no effect on the flow rate and flow rate of the medium, and it does not rust, exemption from maintenance during the effective operation period.
