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; {Full name of the enterprise} - The flexible and rigid waterproof casing produced by the manufacturer's innovative pipeline should be replaced by a concrete wall if it is not concrete, and the casing should be solidified in the wall at one time; Waterproof casing is used in construction, chemical, steel, tap water, sewage treatment, and other units.

The difference between rigid waterproof casing and flexible waterproof casing:

The rigid waterproof sleeve is a steel pipe with an outer wing ring (made of steel plate ringly sheathed on the steel pipe), which is installed inside the wall (mostly concrete walls), and is used for ordinary pipes to penetrate the wall, facilitating the waterproof of the wall; In addition to the outer wing ring, there are also retaining rings inside the flexible waterproof sleeve, such as flange inner threads, which are sold in a complete set, or can be processed by yourself. They are used for pipelines that require shock absorption, such as when the pipes connected to the water pump pass through the wall.

The main reason is that the use of flexible waterproof sleeves is different. Flexible waterproof sleeves are mainly used in places with high requirements such as civil air defense walls and water pools, while rigid waterproof sleeves are generally used in places where pipelines such as basements need to pass through.

When pipes entering the house from underground pass through the exterior wall of the building, rigid waterproof sleeves need to be installed. Sleeves through walls (pools, slabs, etc.). It is divided into two types: rigid and flexible. {Full name of the enterprise} - The waterproof sleeve produced by the manufacturer's innovative pipeline is allowed to have deformation after installation - flexible; No deformation is allowed - rigidity.

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.

Advantages of flexible waterproof casing

Type B flexible waterproof sleeve is a hardware fitting suitable for structures where pipes pass through walls and are subject to vibration or tight waterproof requirements. The flexible waterproof sleeve produced by Innovative Pipeline has a welded water stop wing ring on the outside, and is internally equipped with a sealing gasket. The flange is connected with internal wires. It is designed and customized according to the actual situation of pipeline installation. It is required to be waterproof on both sides of the wall. It is recommended that you use flexible waterproof sleeves. For example, both ends of the pipe wall of the submersible water pump water supply and drainage system should be provided with waterproof treatment to prevent structural water seepage!

Features of flexible waterproof casing

When the upstream surface is a corrosive medium, sealing materials can be used to seal the gap

If there is a non concrete wall where the casing penetrates the wall, it should be partially converted to a concrete wall, with the pouring circumference 200 larger than the flange ring diameter (D5), and the casing should be poured and fixed in the wall at one time.

The thickness of the concrete wall at the pipe penetration should not be less than 300, otherwise one or both sides of the wall should be thickened, and the diameter of the thickened part should be at least D5+200

The weight of the casing is calculated with L=300. If the wall thickness is greater than 300, it should be calculated separately.

5 Flexible filler materials: asphalt hemp fiber, polystyrene board, PVC foam plastic board.

Sealing paste: polysulfide sealing paste, polyurethane sealing paste.

Use of flexible waterproof casing

The 02S404 waterproof sleeve produced by Innovative Pipeline 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.
