Flanged/Union Threaded Connection Flexible Rubber Expansion Joints Pipe Connector Rubber Compensator
Rubber Flexible Joint Features:
Small size, light weight, good elasticity, easy installation and maintenance
Installation can produce transverse, axial, angular displacement, not subject to pipeline not centered, flange is not parallel and other restrictions
When 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.

The rubber metal pipes are installed free of tension.
The mounting length should be 70mm, do not load on train, twist or bend position.
The installation should be in an easily accessible location where maintenance and inspection of the system is easy to do.
Additional seals are not required, since rubber protrudes at the sealing surface.
Keep the joint away from heat sources such as welding machines or sun light.
Do not assemble the joint directly in touch with rubber surface or other fitting.

Rubber Flexible Joint Professional Manufacturer:
Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage.
Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage.
Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system.
Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
Application:
Water, Sea Water, Fresh Water, Sewage Fluid, Warm Water, Weak Acid Fluid, Soda Fluid, etc. Pipeline
Connected with pumps, valves, firefighting equipment, HVAC system, etc.
