Product Description Product DescriptionFlanged/Union Threaded Connection Flexible Rubber Expansion Joints Pipe Connector Rubber CompensatorRubber Flexible Joint Features:Small size, light weight, good elasticity, easy installation and maintenanceInstallation can produce transverse, axial, angular displacement, not subject to pipeline not centered, flange is not parallel and other restrictionsWhen working, it can reduce the noise transmitted by the structure, with strong shock-absorbing ability. Rubber joints have good comprehensive performance and are widely used in chemical industry, construction, plumbing, fire fighting, electric power and other basic projects.Rubber joints are mainly used in pipelines with large vibration and frequent changes of heat and cold, which can absorb the vibration generated by the work of the pump, thus reducing the noise and avoiding the loosening of the screws, and thus are also called shock absorbers or vibration dampers.Rubber flexible joint is a kind of pipeline connection parts, can connect two different materials, different straight through or different axis of the pipeline. Rubber flexible joint can relieve the pipeline system due to thermal expansion and contraction, frequent vibration and other reasons caused by pipeline deformation, displacement and other problems, so as to protect the safety operation of the pipeline.Advantages: good elasticity, sealing, corrosion resistance and so on.
