JDX Reducing Rubber Joint big and small joint
Flexible concentric reducing rubber joint is also called shock absorber, expansion joint, pipe shock absorber, shock absorber throat and soft joint. It is a flexible joint of metal pipe, which is composed of rubber ball and loose metal flange with inner rubber layer, nylon cord fabric reinforcement and outer rubber layer composite.Now the foreign advanced production technology is introduced, the inner layer is under high pressure in the production process, the nylon cord cloth and the rubber layer are better combined, the working pressure is higher than the ordinary flexible rubber joint, the quality is better.It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.

The main feature is that it can solve the problem of different diameters when metal pipes are connected, at the same time, it has the function of shock absorption and noise reduction, which can save the installation parts of pipes and cost.It is composed of rubber ball and loose metal flange with inner rubber layer, nylon cord fabric reinforcement, outer rubber layer composite.It can be widely used in water supply and drainage, circulating water, HVAC, fire fighting, papermaking, pharmaceutical, petrochemical, Marine, water pump, compressor, fan and other piping systems.The ordinary type is used for transporting air, compressed air, water, sea water, oil, acid and alkali of -15℃ ~ 120℃.The special type is used for conveying above medium or oil, concentrated acid and alkali, solid material above -30℃ ~ 250℃.
Flange Materials/Drilling:
The XUVAL Style rubber expansion joints are furnished complete with plated carbon steel flanges for corrosion protection. carbon steel 304 or 316 stainless steel flanges are available upon request as well as ANSI 150/250/300 lb.Other options include alternative elastomers, filled arches, stainless steel backing rings, or special bolt hole drilling. Large inventories are kept at our warehouses to allow for quick delivery.
