Brief introduction of double-sphere rubber expansion joint 

Flexible rubber joint is also called  shock absorber, pipe shock absorber, shock absorber larynx, flexible rubber joint, rubber soft connection, soft connector. Flexible single ball rubber joint is flexible coupling of metal pipe, composed by inner layer, Nylon cord fabric enhanced, outer layer composite rubber ball and metal flange. Working pressure is higher than ordinary flexible rubber joint. The product has the characteristics of high pressure resistance, good flexibility, big displacement, balance pipe deviation, absorb vibration, reduce noise, convenient for installation.

Application of double-sphere rubber bellows 

As rubber has superior capability in resistance of acid, alkali, oil and electrolyte, rubber joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical, Petrochemical, Marine, Power Generation, Pulp and Paper, Steel Mills, Water and Wastewater Treatment, Building Construction, Heavy Industry, Freezing and Sanitary Plumbing.

Solve the problem of different caliber metal pipe connections, while noise damping effect, saving pipeline installation parts and cost savings. It consists of the tube, nylon cord enhanced rubber outer layer composite ball and loose metal flange. With high pressure, good elasticity, displacement volume, balance pipe error, absorb vibration and reduce noise effects, easy installation, and can be widely used in water supply and drainage, recycled water, HVAC, fire fighting, paper, pharmaceutical, oil chemicals, shipbuilding, water pumps, compressors, fans and other piping systems. Common type used to transport air -15 ℃ ~ 120 ℃, the air, water, sea water, oil, acid and alkali. Special type used to transport -30 ℃ ~ 250 ℃ over the medium or oil, strong alkali acid concentration, solid materials.

According to clients demand and product performance, metal and seal ring materials will be selected strictly. High—strength antifouling paint is painted outside and the joint bolt is made of high—strength carbon steel or stainless steel, since there is some space between body and expansion, so axes and radial displacement will appear. Inside pipe, it becomes available to compensate and release pipe blind plate propulsion and makes it easy to maintain and change pump and valve. Therefore, it is an ideal matching product for pipe’s installation and operation.
