Product Description

Reducing rubber joint, also known as reducing damper, pipeline damper, shock throat, flexible joint, flexible joint and high pressure joint.
The popular interpretation of reducing rubber joint is "the rubber pipe fittings that need reducing and reducing connection"
Reducer rubber joint, reducer rubber reducer, reducer rubber reducer, and concentric reducer rubber joint are collectively referred to as reducer rubber joint. They are mainly used in pipes with different pipe diameters or need to be connected with reducer. The maximum bearing pressure is 1.6MPa, with good elasticity, large displacement, low resonance noise of pipeline unit, convenient installation, and compensation for pipe displacement, which well fills the gap of large reducer pipe connection in the industry.
main features 
It can solve the problem of different diameters when connecting metal pipes, and has the effect of vibration reduction and noise reduction, which can save the installation parts of pipes and save costs. It is composed of rubber ball and loose metal flange with inner rubber layer, nylon cord fabric reinforcement, outer rubber layer composite. It has the characteristics of high pressure resistance, good elasticity, large displacement, balancing pipeline deviation, absorbing vibration, good noise reduction effect and convenient installation. It can be widely used in water supply and drainage, circulating water, HVAC, fire protection, paper making, pharmaceutical, petrochemical, ships, pumps, compressors, fans and other pipeline systems. The common type is used to transport air, compressed air, water, sea water, oil, acid, alkali, etc. at - 15 ºC - 120 ºC. Special type is used to transport the above media or oil, concentrated acid and alkali, and solid materials above 30 ºC~250 ºC.
