Introduction: 1. According to the classification of embedded waterproof casing, the embedded waterproof sleeve is a kind of hardware pipe fitting which is suitable for pipeline passing through the wall with vibration or strict waterproof requirements. Generally, it is manufactured according to S312 and 02s404 standard atlas developed and designed by the Academy of Architectural Sciences. Embedded waterproof casing

1. Embedded Waterproof casing Classification, embedded waterproof casing is a kind of hardware fitting which is suitable for pipeline passing through the wall with vibration or strict waterproof requirements. Generally, it is manufactured according to S312 and 02s404 standard atlas developed and designed by the Academy of Architectural Sciences. Embedded waterproof casing is used for underground construction, chemical industry, steel, construction, chemical industry, hard steel, tap water, wastewater treatment and other enterprises. Stretch Flexible waterproof casing It is applicable to the structure (building) where the pipeline passes through the wall and does not bear the vibration and expansion deformation of the pipeline. It is suitable for the renewal and reconstruction of buildings (structures) or pipelines with limited space or pipelines installed before buildings (structures) or pipelines.
   Rigid waterproof casing It is applicable to the structure (building) where the pipeline passes through the wall and does not bear the vibration and expansion deformation of the pipeline. It is suitable for the reconstruction of buildings (structures) or pipelines with limited space or pipelines installed before buildings (structures) or pipelines.
Flexible waterproof sleeve is a kind of hardware fitting which is suitable for pipe passing through the wall with vibration or strict waterproof requirements. In general, the manufacturer is based on the S312 and 02s404 standard atlas developed and designed by the Academy of Architectural Sciences. On the basis of the rigid waterproof casing, two wing rings and two short plates are added to the rigid sealing protective casing on both sides, with great difference. The two diaphragms and wing rings have strong resistance to seismic waves.
2. Installation requirements of embedded waterproof casing
I. after the wing ring and steel sleeve are produced and processed, the wall shall be painted with one coat of primer (including camphor or cold primer oil).
II. The net weight of raw materials listed in the size table of embedded waterproof casing is the net weight of steel casing (the length of casing L is calculated as 200 mm) and the net weight of wing ring. Steel sleeve and wing ring are made of A3 material.
III. If the embedded waterproof sleeve crosses the wall, the concrete wall should be used instead of the non concrete wall. The cast-in-place casing (D4) of cast-in-place concrete should be more than 200 mm in diameter. The filling material in the casing shall be compacted.
4. The thickness of the concrete wall at the waterproof sleeve shall not be less than 200 mm, or one or both sides of the type wall shall be thickened, and the diameter of the thickened part shall be at least 200 mm greater than that of the wing ring (D4).
V. the rigid waterproof casing shall be filled with oil hemp and stone wool cement, and then compacted.
6. The embedded waterproof sleeve is suitable for cast iron pipe and non-metallic material pipe, but the relative specification shall be adjusted according to the thickness of wall.
Pipe into the room or underground, water into each area to deal with everyone's water problems. When based on the heavy load of underground wall, the capacity of water pipe will inevitably be extruded. Therefore, it is necessary to install rigid waterproof casing to maintain the water pipe. Rigid waterproof casing has excellent user evaluation. If we pay attention to this kind of problems in the whole process of application, the rigid waterproof casing will have very good practical waterproof effect.
