What are the specification requirements for waterproof casing

For plumbers, the installation of pipes should be clear and unambiguous. We need to protect some pipes and install waterproof casing. Do you know about rigid waterproof casing? This is to prevent water from leaking out of the side wall. It is required that the water pipe passing through the pool should be installed with a ring letter waterproof casing. Next, let's see what we need to pay attention to during the installation process.
In the installation of the pipe before the installation of waterproof casing, the first thing to do is to check whether the waterproof casing is intact. If it is damaged, it should be replaced in time, and whether the size is in line with the drawings and site construction requirements. Second, to check whether the pipe is damaged, whether there are cracks, trachoma, etc., and to solve the problem in advance. Thirdly, it is necessary to check whether the socket is in place and whether the socket itself is dense. Finally, it is necessary to check whether the slope of the pipe is appropriate and there should be no reverse slope. In addition, it should be noted that the slope of the pipe at the roof outlet should be added accordingly. Waterproof casing is not standardized: on the one hand, it means that the thickness of the tube itself does not meet the requirements of the drawings, resulting in the waterproof casing cannot be used; on the other hand, the thickness of the tube itself cannot meet the requirements of the drawings. On the other hand, it refers to the burr and unevenness at both ends of the waterproof casing due to the selection of gas cutting method of cutting. Incorrect orientation of the casing's reservation: this is to be installed during construction and the waterproof casing above is consistent. If the installation principle is not followed, it may lead to the accuracy of the reserved approximate orientation to install the casing, and the whole structure can not work properly.
Pay attention to corrosion prevention: If the upstream appearance of the waterproof casing is corrosive materials, it is necessary to use plugging materials to block the gap. For example, when installing a non-concrete wall and the upstream appearance of the casing is corrosive material, it is necessary to change part of the wall to a concrete wall and ensure the thickness of the wall, otherwise it will not work. Improper floor height: When the pipe passes through the wall and floor, metal or plastic sleeves should be supplied. For housings installed on the floor, the top should be higher than the finish floor, usually 20 mm; for housings installed in bathrooms and kitchens, the bottom should be flush with the bottom of the floor and the top should be about 50 mm higher than the finish floor; for housings installed on the wall, the ends should be flush with the finish exterior. This is common with the installation of the above waterproof casing in the construction process. If the installation is not in accordance with the principle, the reserved position for the installation of waterproof casing may not be accurate enough, which will lead to the entire construction can not be carried out properly.
