Product performance

 Relying on rubber`s special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, the product is manufactured 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 information. 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 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 reducing librations and noise transfer. It is designed with smooth walls and has no influence on flow speed of medium in tests and never rusts either. Therefore, maintenance is not necessary in valid operation period.


The Application Range of Flexible rubber joint

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.

Flexible Rubber Joint Installation Directions

  1. During pipe construction, the flexible rubber joint shall be kept natural, do not deform the product purposely when installing.
  2. During installing flange losing rubber joint, the enhancing ring(jutted inner steel wire rope)of spherical two ends shall be completely installed inside the flange slot so as to prevent balls to break away from flanges when pipes bear pressure, During installing bolts, screw down sym-metric six/four bolts and keep balls and flanges remaining in order.
  3. When connecting rubber joint and pipe flange, the bolt pole shall extend to the pipe flange so as to prevent from crushing or pricking the coved screw thread expanding because of pressure, all bolts shall be pressured and screwed down and word congruously. If the surrounding circumstance is bad, spring washer and flat gasket shall be added to prevent bolts from losing.
  4. If arch/high arc rubber joints are adapted(for six-angle bolt cannot pass through flange hole),double-head bolts shall be used and try to reduce spherical screw thread jut and avoid crushing balls expanding under pressure and prevent early damage of rubber.
  5. When frequently use the rubber joint or near water(oil)pup nozzles, stop block shall be added on both ends of flans so as to reduce the impace on pump and pipe caused by the length changes of rubber joint.
  6. When adapting over Dn1000 © Lrubber joint, some length short pipe shall be made on one flange end so as to help installation and reduce labor strength. After connecting rubber joint and the short pipe and the other pipe, weld the short pipe and relevant pipe together.
  7. In order to remove the radial deviation formed by short pipe welding, use round steel or other relevant metal to temporarily weld flanges on pipe′s two ends and make the rubber joint and flange be a steel body. After welding, remove the welding again and keep the rubber joint natural as usual.
  8. When welding metal and flange, remember to cover the rubber joint with shielding and prevent from burning balls.
