China National Standards Drafting Unit of Rubber Joint 
Qualified Joint Supplier in Nuclear Power Plant 

Product Performance 
Relying on rubber's special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, +86-371-60312250 the product is manufactures 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 arc height, curve length owns multi-functional displacement. Especially, it is suitable to be used where there are complex geologic conditions and large sedimentation range and frequent cold and hot changes 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 radiation. Rubber is a kind of low conduction material, so it can be an ideal product for medium in tests and never rusts either. Therefore, maintenance is not necessary in valid operation period. 
Application Range 
Equipped with the excellent comprehensive performances 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 powder material and gas for its high abrasive resistance. 
In addition, special notifications are hereby conducted for design units and clients so as to ensure the project quality, please note to install anti-break stop device, if our products are designed to install close to pump exit nozzle and pipes' corner. If your pipes need to be buried, please use our patent-buried protective devices. In a word, remark requirement for use, and we will provide satisfactory service to you.
