The service life of the steel flexible waterproof casing

For installation precautions waterproof casing in actual use, the use of the process, many people are not pay attention to its installation time and installation method or not pay attention to its use method. It is because of its location and method reasons will affect the service life of waterproof casing. In the actual life, must pay more attention to its use of time, and to its correct use of skills and methods, otherwise it will bring a lot of harm to themselves. Waterproof casing in the use of the process, we are necessary to check after the selection or production, is to enable people to understand whether this material meets the actual needs, there is a need to pay attention to its welding method is reasonable or the process is correct and other issues, which also allows people to know through its detailed understanding to know. For the waterproof casing in the construction must do a good job of security measures, but also to have a special person to operate in this area to enable us to more effectively ensure safety.
It should be noted that try to choose the kind of wall thickness of the waterproof casing can be thick, if the choice is no wall thickness, it will allow us to be affected in the use of the process but is the result of unavoidable. There is a certain thickness of the casing, and the thickness of the casing should meet the relevant national regulations and should be greater than or equal to the casing wall thickness of more than two times, if less than the relevant national regulations can not be met, while the hole diameter should be calculated according to the standard, and to ensure that the hole diameter is not less than the relevant national regulations. Should choose the appropriate specification of the casing, and according to the pipe diameter or caliber size to choose the casing wall thickness, thickness, etc., if the wall thickness is too thick, it is easy to produce cracks due to pipe expansion, thus causing leakage problems. In the need to install the compensator must be strictly in accordance with the design requirements, and in accordance with the provisions of the specification to find a good installation position to ensure that the pipeline is in working condition; in addition, the operation can be carried out manually, but must do the operation specifications, not arbitrarily removed, replaced.
Waterproof casing through the wall at the outer surface needs to be coated with anti-rust paint to prevent rusting and aging. There are two ways of anti-corrosion wall: spray paint and hot dip galvanizing. When spraying paint, pay attention to the presence of oil around the waterproof casing. When painting primer and topcoat, pay attention to the thickness of the primer and topcoat, and the primer and topcoat should be painted at intervals. The primer should be applied evenly and carefully. In addition, the cement mortar will be applied outside the casing, the gap between the cement mortar and the wall is coated with paint, the wall is coated with paint, and then the gap is filled with waterproof cement mortar to protect the cement mortar, and then the gap is filled with waterproof cement sand for filling, and finally the wall is sealed with sealant to prevent water from seeping out of the gap. Waterproofing materials are divided into two types: rigid waterproof casing, flexible waterproof casing and ordinary waterproof casing. Different types of waterproofing materials have different performance characteristics and scope of use.
