Rubber joint:

Relying on rubber’s special performance as long range elasticity ,air impermeability ,medium ,climate and radiation resistance ,the product is manufacture through combination of inclined polyester cord fabric with high strength and cold and hot stability and molding cross linking under high pressure and temperature ,it has high density inside and can bear high pressure and has excellent elastic deformation .the product’s structural design in cross section are high ,curve length owns multi-function displacement .Especially , it is suitable to be used where there are complex geologic conditions and large sedimentation range and frequent cold and hot change that will damage pipes inside pipes .it can remove physical damage of displacement of pump ,valve and pipes through rubber’s flexible gliding shift and distorting mechanical heat transfer and relation .Rubber is a kind of low condition material ,so it can be ideal product for reducing librations and noise transfer .It is designed with smooth walls and has no influence on flow speed of medium in test and never rusts either .Therefore ,maintenance is not necessary in valid operation period..

 Performance characteristics:

1.Small volume.light weight .good elasticity.easy installation and maintenance.

2.When installation to product transverse ,axial, angular displacement ,pipe

impassability heart ,flange unparallel restriction.

3.Work can decrease the structure noise ,vibration absorbing ability.

Application scope:

Equipped with the excellent comprehensive performance of flexible rubber joint , the product can be used for lift and transportation of raw water and sewage ,transportation of water supply ,cooling cycle water of thermal power plant ,condensate water of metallurgy industry and chemical materials of chemical industries ,cooling and dilution of oil and chemical industries and flexible connection of other industries .it is also suitable to transport all grain and power material and gas for its high abrasive resistance
