Steel flexible waterproof casing
Scope of application: Stainless steel flexible waterproof casing is suitable for structures where the pipe passes through the wall and is subject to vibration or tight waterproofing requirements. The flexible waterproof casing should be replaced with a concrete wall through the wall, and the casing must be solidified once in the wall; the flexible waterproof casing is widely used in construction, chemical, steel, tap water, sewage treatment, and the like.
The steel flexible waterproof casing is suitable for structures where the pipeline passes through the wall and is subject to vibration or strict waterproofing requirements. It is generally manufactured according to the 02S404 standard atlas developed by the Institute of Building Science. The flexible waterproof casing penetrates the wall of the wall. If it is non-concrete, it should be replaced with concrete wall, and the casing must be solidified once in the wall; flexible waterproof casing is widely used in construction, chemical industry, steel, tap water, sewage treatment, etc. unit.
The steel flexible waterproof casing is the passage for the pipeline to the pool when the pool is made. Because ordinary casing is difficult to seal, there is water leakage between the casing and the pipe, and water leakage between the casing and the wall. The waterproof casing is used to solve the water leakage between the casing and the wall, and the sealing between the casing and the pipeline cannot be solved. The flexible waterproof casing can solve both problems.
The casings produced by Henan Liwei Industry Co., Ltd. can be divided into: ordinary casings - 2-4 cm thicker than the pipes to be used, fixed in the wall or plate, and the pipes pass through. The flexible casing - that is, the sealing between the casing and the pipe with a flexible material to seal. Steel casing - that is, the sealing between the casing and the pipe is achieved by sealing with a steel material. Waterproof casing--that is, the environment used for the casing is to prevent liquid from leaking or leaking (such as pool, septic tank, basement, etc.), that is, adding no less than one turn of the waterproof wing on the outer wall of the casing. When the tube is poured into the wall, it becomes a whole, avoiding the occurrence of cracks due to the expansion and contraction factor and leakage.
Our company can produce various types of waterproof casings according to national standard or non-standard. The GB-type waterproof casing is completely selected according to the 02S404 or 02S312 standard atlas of the Ministry of Construction, and has strict requirements on flange thickness, wing ring thickness, pipe diameter and thickness. Non-standards are in the case of the shape and the approximate structure conform to the standard atlas. When selecting materials, the thickness of the flange, the thickness of the wing ring, the diameter and the thickness of the pipe are considered to be relaxed. Strictly speaking, these are unqualified products. Of course, certain relaxation criteria within the degree will not affect the use.
The specifications of the flexible waterproof casing produced by Liwei Industrial are between DN50mm and DN3200mm. The flexible filling material is bitumen, hemp, polystyrene board, polyvinyl chloride foam board. Sealing paste: polysulfide sealant, polyurethane sealant.
