Introduction: Waterproof casing is also called through wall casing. Generally, flexible waterproof casing can be used for buildings with vibration or strict waterproof requirements in the area where the pipeline crosses over the wall. After the production and manufacture of part of the waterproof sleeve is carried out, its surface shall be painted once (including

Waterproof casing It is also called through wall casing. Flexible waterproof casing Generally, the area where the pipeline crosses over the wall is subject to vibration or strict waterproof requirements. After the production and manufacture of a part of the waterproof sleeve, the surface of the pipe shall be painted once (including camphor Dan or cold primer oil). Waterproof casing is divided into Rigid waterproof casing And flexible waterproof casing. Flexible water-proof casing is mainly used in areas with high requirements, such as type I civil air defense wall and water storage tank. Rigid waterproof casing is generally used in basement and other places where pipelines need to pass through.
S30212, which has been researched and developed by the Institute of building and water proofing, has been manufactured according to the requirements of building engineering standard s3404. If the wall where the flexible waterproof casing passes through the wall, it should be changed into concrete wall if it is not concrete, and try to solidify the waterproof sleeve in the wall at one time; the flexible waterproof casing is widely used in construction engineering, chemical enterprises, stainless steel plate, domestic water, wastewater treatment and other companies.
The rigid waterproof sleeve is a seamless pipe with multiple flange rings (carbon steel plate is made of annular sleeve on the seamless pipe), which is installed in the wall (see concrete wall), which is used for general pipeline passing through the wall, which is beneficial to the waterproof of the wall. In addition to the external wing ring, the flexible waterproof sleeve is also a baffle ring. The inner wire of the flange is direct, which can be sold by mechanical equipment, and can also be manufactured by itself. It can be used for shock absorption For example, when the pipeline connected with the water pump motor passes through the wall.
Both flexible and rigid water-proof sleeves are hardware fittings used for pipelines to turn over the walls of buildings subject to vibration or strict waterproof requirements. They are often found in construction engineering, chemical enterprises, stainless steel plates, domestic water and wastewater treatment companies.
The rigid waterproof casing is different from the flexible waterproof casing in art and appearance. The flexible waterproof casing has a rubber sealing ring inside, which can prevent leakage when used in the water tank wall. Their installation length is different. The standard length of flexible casing is 300 mm, while the standard length of bending rigidity waterproof casing is 200 mm. However, they have one thing in common: they can be arbitrarily lengthened or reduced according to the construction requirements.
The waterproof sleeve is composed of seamless pipe and external wing ring. It is installed in the wall (see concrete wall) for general pipeline crossing the wall, which is beneficial to the waterproof of the wall. However, the waterproof sleeve only fully considers the pipeline passing through the wall. What should the surface of the waterproof sleeve do?
A better way is to manually service cleaning, using solvents. Organic solvent can clean the surface of stainless steel plate, and then remove the oil, grease, dust and other organic matters on the surface of stainless steel plate, but this method can not remove the rust and other stains on the surface of stainless steel plate. The surface of stainless steel plate can be polished with wire brush and other common tools, and the loose or warped diazotization reaction skin, rust, weld through and other stains can be removed. Phosphating can also remove diazotized reaction skin, rust and old coating, and sometimes it can be used as the re-treatment after sand blasting. However, the phosphating treatment is more air pollution and causes great damage to people. Generally, phosphating treatment is not recommended for waterproof casing. The better way is to carry out eruption antirust, which is based on the output power motor to promote the high-speed operation of the eruption blade, which can not only solve the problem of rust, hydroxide and waste, but also ensure the uniform surface roughness of seamless pipe under the obvious destructive effect of metal composite material and sliding friction force.
In the process of using the waterproof casing, once the corrosion is caused, it should be eliminated immediately. Otherwise, it will not only damage the smooth transmission of the pipeline, but also cause more sediment in the solution, and the interaction between the pipe and the waterproof sleeve will cause polarization, which needs to be put into action immediately. For this kind of waterproof casing which has been used for a long time beyond the standard, it is strongly recommended to dismantle it immediately, otherwise it will become more and more nominal after comparison, and it will not play a role in maintenance of the pipeline, which will pose a great threat to the normal operation of the pipeline. Shanghai Luoying manufacturing waterproof casing, wholeheartedly for you to express the various difficulties in the waterproof casing, improve the normal maintenance and repair work of the pipeline, and ensure the normal operation of the pipeline.
Shanghai Luoying manufacture flexible waterproof casing, strictly abide by ~ waterproof casing standard atlas 02s404 standard manufacturing, product quality comparison your trust. And our company can adjust the length of the goods according to the different pipeline installation geographical environment, promote the thickness of the goods into the wall as soon as possible, so as to have the seismic grade bearing capacity characteristics. If you have any doubts and regulations, you can call our Shanghai Luoying marketing department, we will uphold a more sincere service level to provide you with a comparative pipeline solution, to ensure the safety factor operation service of your pipeline comparison new project.
