Introduction: Generally, the raw materials of flexible waterproof casing are carbon steel, cast steel, galvanized steel and stainless steel, but the general customers are not very familiar with this kind of material. In areas without special requirements, most of us choose carbon steel material to manufacture flexible waterproof casing; if it happens, it is also a rule

flexibility Waterproof casing The raw materials are generally carbon steel, cast steel, galvanized steel, stainless steel four kinds of materials, but the general customers are not very familiar with this, there are no special requirements of the area, most of us choose carbon steel material to produce Flexible waterproof casing If there is a regulation, we can also use different materials to manufacture flexible waterproof casing according to the specific application situation.
Flexible waterproof sleeve is a kind of hardware pipe fitting which is suitable for the structure with vibration or strict waterproof regulations where the pipeline crosses the wall. The general production enterprise is manufactured according to S312 and 02s404 standard atlas developed and designed by the engineering and Building Science Research Institute. The wall where the flexible waterproof casing passes through the wall shall be changed into concrete wall in case of non concrete, and the casing shall be condensed in the wall at one time.
After the pipeline crosses the floor, some construction teams do not carry out civil engineering support for the convenience and convenience. They only carry out simple blocking and then plug the hole with mixed mortar. In addition, the surface of the rigid polyvinyl chloride pipe is relatively smooth, and the bonding with the concrete is not very strong. Therefore, it is easy to cause serious floor leakage and endanger all normal applications of residents. The proper method is: add casing pipe in advance, support with civil engineering after pipe installation, and use C20 fine aggregate concrete to pour and tamp compactness in two times. After the concrete pouring is completed, the plastering layer or surface layer engineering construction shall be integrated, and the wall shall be built around the pipeline to form a water stop ring with the thickness of not less than 20 mm and the total width of not less than 30 mm.
Waterproof casing is also called through wall casing, which acts on the place where the casing crosses the road, railway, street, etc. in order to prevent the pipeline from being crushed under load, protective casing is set outside the pipeline. Due to the different construction environment, the selection of waterproof casing is also different. The common ones are rigid and flexible.
The structure of flexible water-proof casing is external welding water-proof wing ring, with sealing gasket set inside, and inner flange wire connection. It is designed and customized according to the specific situation of pipeline installation, so it is necessary to make waterproof on both sides of the wall. It is recommended to use flexible waterproof sleeve. For example, waterproof treatment should be given to both sides of the pipe wall of the water supply and drainage system of the deep submersible pump, or the position of the water tank through the wall pipe should be modified with flexible waterproof sleeve to avoid structural leakage.
Type I and type II sealing ring can be used for the other end of the casing, which is suitable for the sealing of type II. It should be noted that when the temperature exceeds the application range (- 20 ℃ - + 80 ℃) sealing materials and product materials will be investigated. The installation of waterproof casing should follow the installation standard as much as possible. If the actual situation does not allow, please show the specific application environment to carry out the design. If there are anti-corrosion provisions, the materials for rotten materials must be used.
