Relying on rubber's special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, 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.
