Introduction: Luoying both ends of the sealed waterproof casing, also known as through the wall casing, through the wall pipe. The flexible waterproof casing is generally applicable to the structure where the pipeline crosses the wall and is subject to vibration or strict waterproof regulations. After the processing of a part of the casing, the outer wall of the casing shall be painted with one coat of top coat (including Zhangdan)

Both ends of Luo Ying are sealed Waterproof casing It is also called through wall casing. Flexible waterproof casing It is generally applicable to the structure where the pipeline crosses the wall and is subject to vibration or strict waterproof regulations. After the processing of part of the casing pipe, the outer wall of the pipe shall be painted with one coat of top coat (including camphor Dan or cold primer oil). Division of waterproof casing Rigid waterproof casing And flexible waterproof casing. The flexible water-proof casing is mainly used in the areas with high regulations such as civil air defense wall and pool, while the rigid waterproof casing is generally used in the places where pipelines such as basement should pass through.
Luoying two ends sealed waterproof casing flexible waterproof casing: external welding water stop wing ring, internal sealing gasket, flange inner wire connection, designed and customized according to the specific situation of pipeline installation, used for both sides of the wall need to be waterproof, so it is recommended to use flexible waterproof sleeve. For example, both ends of the pipe wall of the water supply and drainage system of the deep submersible pump should be treated with waterproof treatment to avoid structural leakage!
Luoying sealed waterproof sleeve at both ends of Luoying flexible waterproof sleeve is a kind of hardware pipe fitting which is suitable for structures with vibration or tight waterproof regulations where the pipeline crosses the wall. The general production enterprises are manufactured according to S312 and 02s404 standard atlas developed and designed by Architectural Science Research Institute. If it is necessary to use flexible casing pipe in concrete wall and wall, it should be used for waterproof treatment of non concrete wall and wall.
Luoying sealed waterproof casing at both ends rigid waterproof casing: the outer wall of the casing is welded with waterproof wing ring. According to the structural engineering drawings issued by the Design Institute, the waterproof casing should be embedded in the concrete wall in advance. If only considering the pipe through the wall, but not considering the waterproof performance of both sides of the wall and the displacement and deformation of the pipeline after passing through the wall, the rigid waterproof casing can be selected, which is mostly used for the wall waterproof of basement and civil air defense engineering.
Luoying sealed waterproof casing at both ends of Luoying rigid waterproof casing is steel pipe with flange ring (steel plate ring is sheathed on steel pipe), which is installed in the wall (see concrete wall). It is used for general pipeline through the wall, which is conducive to the waterproof of the wall. In addition to the external wing ring, the flexible waterproof sleeve also has a baffle ring inside. The flange inner wire can be sold in sets or processed by itself to meet the needs of shock absorption The pipeline to be used, such as when the pipe connected with the water pump passes through the wall.
Note for installation of sealed waterproof casing at both ends of Luoying: when the upstream side is corrosive medium, plugging materials can be selected to block the gap. If non concrete wall is encountered, concrete wall should be partially used. The pouring scope should be 200 larger than the wing ring diameter (D5), and the casing should be poured into the wall at one time. The thickness of the concrete wall at the pipe crossing shall not be less than 300, or the wall thickening type at one side or both sides shall be used. The diameter of the thickened part is at least d5200. If the wall thickness is more than 300, the wall thickness shall be calculated as l = 300. Both ends of Luoying sealed waterproof casing, whether flexible or rigid, is used for pipeline crossing the wall of buildings subject to vibration or strict waterproof regulations. It is commonly used in construction, chemical industry, steel, tap water, sewage treatment and other units.
