Types and characteristics of waterproof casing.

Waterproof casing has many applications in life, not only to protect internal pipes, but also to effectively prevent leakage. However, during the use of waterproof casing, the wrong type and selection of waterproof casing often makes it difficult for many people to make use of its application. Waterproof casing also requires certain skills in the process of use. Therefore, in the construction process, construction workers should understand the difference between flexible waterproof casing and rigid waterproof casing, and understand the installation method of waterproof casing.
Flexible waterproof casing is used to solve the problem of strict technical requirements for vibration or waterproofing when the pipe goes through the wall, and is suitable for all types of pipes through the wall. General production companies based on the Institute of engineering atlas s312.02s404 standard specification. The pipe should be pre-buried flexible waterproof casing before installation. After the pipe through the casing, the cover flange should be installed, then install the studs and nuts and squeeze the rubber seal. After the deformation of the rubber seal ring, it should be in full contact with the inner wall of the flexible waterproof casing and the outer wall of the penetration pipe to effectively prevent leakage.
Casing is usually used to make pools, which are the channels through which pipes enter the pool. However, it is difficult to seal the ordinary casing, which leads to leakage between the casing and the pipe and easy leakage between the casing and the pipe wall. Only waterproof casing can solve the problem of leakage between casing and wall, but not the problem of sealing between casing and pipe. Flexible waterproof casing can only solve two problems.
2 . Rigid waterproof casing.
Rigid waterproof casing is a steel pipe outer wing ring (ring can be covered with steel plate). Installed inside the concrete wall, usually using a different pipe through the wall, which helps to improve the waterproof performance of the wall.
3 . Extended waterproof casing.
Extended waterproof casing for thicker walls can meet the requirements of extra-thick walls. Other functions and features are the same as normal waterproof casing. The number of stop rings is usually determined according to the length of the passage.
4 . Anti-corrosion waterproof casing.
Anti-corrosion treatment of waterproof casing can effectively prevent the oxidation and corrosion of waterproof casing. Stainless steel waterproof casing is a kind of anti-corrosion waterproof casing, which is widely used in various construction projects. It can achieve good waterproof and anti-corrosion effect, and has a protective effect on various sizes of pipes. Waterproof casing does not need to worry about oxidation and corrosion, because after special anti-corrosion treatment, the service life can reach normal standards, and there are a variety of specifications.
No matter which waterproof casing you choose, you must first understand its characteristics. When choosing the type of waterproof casing to produce, understand its construction introduction, use and purpose. What role it needs to play and where it will be used. Also, understand the level of production capacity of the partner manufacturer. Only then can we choose the product that meets the construction requirements and is cost-effective to ensure that the waterproof casing will be used well at a later stage.
