02s404 flexible waterproof casing

Waterproof casing, also known as through wall casing, through wall pipe. Flexible waterproof casing is generally applicable to structures with vibration or strict waterproof requirements where the pipeline passes through the wall. After the casing part is processed, the outer wall shall be painted with primer (including camphor Dan or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The flexible water-proof casing is mainly used in places with high requirements such as civil air defense wall and pool, while the rigid waterproof casing is generally used in the basement where the pipeline needs to pass through.

Flexible waterproof sleeve is a kind of metal pipe fitting which is suitable for the structure with vibration or strict waterproof requirements where the pipe passes through the wall. The general manufacturers are manufactured according to S312 and 02s404 standard atlas developed and designed by the Architectural Science Research Institute. If the wall where the flexible waterproof casing passes through the wall, the concrete wall should be used if it is not concrete, and the casing must be solidified in the wall at one time; the flexible waterproof casing is widely used in construction, chemical industry, steel, tap water, sewage treatment and other units.  
Rigid waterproof casing is steel pipe with flange ring (steel plate is made of annular sleeve on steel pipe), which is installed in the wall (mostly concrete wall). It is used for general pipeline through the wall, which is conducive to the waterproof of the wall. Besides the external wing ring, the flexible waterproof sleeve also has baffle ring inside. It can be sold in sets or processed by itself. It can be used for pipeline with shock absorption, such as connecting with water pump When the pipe passes through the wall.
Both flexible and rigid water-proof sleeves are hardware fittings for pipes to pass through the walls of buildings subject to vibration or strict waterproof requirements. They are commonly used in construction, chemical industry, steel, tap water, sewage treatment and other units.
The most intuitive difference between the rigid waterproof casing and the flexible waterproof casing is that the appearance is different. The flexible waterproof casing has a rubber water stop ring inside, so as to prevent water leakage when used in the pool wall. Their installation length is different. The standard length of flexible casing is 300 mm, while that of rigid casing is 200 mm. However, they have one thing in common, which can be extended or shortened arbitrarily.

Description of 02s404 flexible waterproof sleeve:
1. All dimensions in this drawing are in mm.
2. Flexible water-proof casing is a structure with vibration or strict waterproof requirements when it passes through the wall.
3. After the casing part is processed, the outer wall shall be painted with primer (including camphor Dan or cold primer oil). The anticorrosion of outer layer is decided by design.
4. If the casing passes through the wall, the concrete wall should be used if it is not a concrete wall. The concrete pouring range should be 200 mm larger than the wing ring diameter (D6), and the casing must be poured into the wall.
5. Otherwise, the thickness of the wall or the pipe passing through the wall shall not be less than 300 mm. The diameter of the thickened part shall be at least 200 mm larger than that of the wing ring (D6)
6. The wall thickness l shall be calculated separately according to the wall thickness of 300 mm.
7. The welding material of casing parts is made of A3 material and welded by T42.

Description of type I flexible waterproof casing:
1. When the upstream surface is corrosive medium, sealing materials can be used to seal the gap.
2. If there is a non concrete wall at the place where the casing passes through the wall, the concrete wall should be used locally. The pouring range should be 200 larger than the diameter of the wing ring (D5), and the casing must be poured into the wall at one time.
3. The thickness of the concrete wall at the pipe crossing shall not be less than 300, otherwise the wall shall be thickened on one side or both sides, and the diameter of the thickened part shall be at least D5 + 200.
4. The weight of casing shall be calculated as l = 300. If the wall thickness is greater than 300, it shall be calculated separately.

Description of type II flexible waterproof casing:
1. Flexible filler materials: asphalt hemp wire, polystyrene board, PVC foam plastic board.
2. Sealing paste: polysulfide sealing paste, polyamide sealing paste.
3. If there is a non concrete wall at the place where the casing passes through the wall, the concrete wall should be used locally. The pouring range should be 200 larger than the diameter of the wing ring (D5), and the casing must be poured into the wall at one time.
4. The thickness of the wall or the part passing through the wall should not be less than the thickness of the wall.
5. The weight of casing shall be calculated as l = 300. If the wall thickness is greater than 300, it shall be calculated separately.
