Stainless steel waterproof casing

Product overview:
Stainless steel waterproof casing can be divided into two types: stainless steel rigid casing and stainless steel flexible casing. The rigid waterproof sleeve embedded in the pipeline crossing the floor and roof can effectively prevent the floor leakage, which is widely used in the building water supply and drainage engineering; the water supply, plant, civil air defense engineering, sewage treatment plant's clear water pool and sewage pool need to pass through the cement wall, and need to be able to move up and down, then flexible waterproof sleeve is needed. These two kinds of waterproof casing are used to prevent the corrosion medium In case of contact, the designer should select suitable corrosion-resistant materials -- 316L stainless steel, 304 stainless steel, 201 stainless steel, etc., according to the medium properties and anti-corrosion requirements.
    When the upstream water surface of stainless steel waterproof casing is corrosive medium, sealing material can be used to seal the gap. For the practice, see 02s404 national standard atlas "flexible waterproof casing (type b) installation drawing". If the non concrete wall is encountered at the casing through the wall, the concrete wall should be locally used, and the pouring range should be 200 larger than the wing ring diameter (D5), and the casing must be poured into the wall at one time, If the thickness of the wall is greater than 300, the thickness of the wall should not be greater than 5 if the thickness of the wall is greater than 300.
Material description:
The stainless steel water-proof casing is made of 304 stainless steel and 316L stainless steel, and its two ends shall be mechanically cut (e.g. with toothless saw). The stainless steel waterproof sleeve is mainly used in pipelines with various corrosive media, such as chemical pipeline, chemical reaction tank and corrosive sewage treatment pipeline.
