Introduction to flexible waterproof casing:
Flexible waterproof sleeves are generally suitable for structures where pipes pass through walls and are subject to vibration or tight waterproof requirements; Rigid waterproof sleeves are generally suitable for structures where pipes pass through walls and require general waterproofing;
The wall where the flexible and rigid waterproof sleeve penetrates the wall should be replaced by a concrete wall if it is not concrete, and the sleeve should be solidified in the wall at one time;
Waterproof casing is used in construction, chemical, steel, tap water, sewage treatment, and other units.
Description of flexible waterproof casing:
1. All dimensions in this drawing are in millimeters.
2. Flexible waterproof sleeves generally pass through structures that are subject to vibration or tight waterproof requirements where they pass through walls.
3. After the processing of the casing part is completed, the outer wall of the casing shall be painted with one coat of primer (including camphor or cold primer oil). The corrosion protection of the outer layer is determined by the design.
4. The wall through which the sleeve penetrates the wall should be replaced by a concrete wall if it is not a concrete wall. The concrete pouring range should be 200mm larger than the flange ring diameter (D6), and the sleeve should be poured firmly into the wall.
5. The thickness of the concrete wall at the pipe penetration point should not be less than 300mm. Otherwise, one or both sides of the wall should be thickened. The diameter of the thickened part should be smaller than the flange ring diameter (D6) by 200mm
6. The material weight of the casing is calculated separately based on the wall thickness L of 300mm.
7. The welding material for casing components is made of A3 material and welded with T42.
Type 02S404 waterproof sleeve is mainly used for working conditions where there is vibration or strict waterproof requirements at the place where the pipeline passes through the wall. On the one hand, it is conducive to the installation and disassembly of the pipeline, as well as seepage prevention and leakage prevention, and on the other hand, it also protects the building from water and vibration damage.
