Use and storage of flexible waterproof casing seals.

Rubber seals are available in round and trapezoidal cross-sections. In addition to the shape and structure, there are various options for the material of the rubber ring. Natural rubber is generally used, but various special materials can be selected according to special fields, such as acid and alkali-resistant neoprene, oil-resistant nitrile rubber, wear-resistant butyl rubber, and EPDM rubber with good overall performance.
 
The cross-section is round rubber seal. Its working principle is to make the gland and short tube deformation by squeezing. The contact area with the pipe is bigger and the waterproof effect is better. In addition, it has good elasticity and reductive prototype performance, and can be used for a long time without being damaged by the environment. The cross-sectional trapezoidal rubber seal works on the same principle as the round rubber ring. The difference is that the sealing performance of this rubber ring is better because the contact surface of trapezoid will be larger than that of round after extrusion, so the sealing performance of trapezoid rubber ring is better, but the cross-sectional rubber ring of these two is really round. The cross section is usually called round rubber ring type I rubber ring, and the cross section is trapezoidal rubber ring type II rubber ring. Different models have unique advantages, so choosing the right one will last longer. 
 
The sealing ring of flexible waterproof casing is mainly made of natural rubber, which has good elasticity and ductility. Different models have different standards, and different requirements require different materials. At one end of the flexible waterproof casing and bolt, there is a retaining ring welded inside the casing as a retaining ring. The outer diameter of the seal ring of the flexible waterproof casing is the same as the inner diameter of the waterproof casing, and the inner diameter is the same as the outer diameter of the flexible waterproof casing. As the seal ring has certain elasticity and expansion, it can cover the outer diameter of the pipe tightly and play the role of shock absorption and sealing. The seal ring of the flexible waterproof casing is the sealing part of the flexible waterproof casing. It is an important part of the flexible waterproof casing and plays the role of waterproof sealing. Storage requirements of flexible waterproof casing 
 
1 . Before leaving the factory, the flexible waterproof casing should take internal and external protection measures to play the flexible waterproof casing extrusion resistance. 
 
2 . When transporting, the test transport company should correct the position of the flexible waterproof casing, not to be stacked at random, and no other items pressed on top of the casing. 
 
3 . Flexible waterproof pipe shall not be discarded or collision during loading and unloading. After the pipe anti-corrosion coating, the flexible waterproof casing should be closed at both ends to prevent damage to the pipe coating during transportation and lifting, and take protective measures. 
 
4 . It is strictly prohibited to use it as a scaffold for other professional equipment, pipelines and operators.
