product feature：

1. When the surface of the water is corrosive medium, the gap can be blocked by plugging materials.
2. If non-concrete walls are encountered at the place where the casing goes through the wall, concrete walls should be partially used, and the pouring circumference should be 200 larger than the diameter of the wing ring (D5), and the casing should be poured in the wall at a time.
3. The thickness of the concrete wall through the pipe 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.
4. The weight of the casing shall be calculated by L=300. If the wall thickness is greater than 300, it shall be calculated separately.
5. flexible packing material: asphalt hemp silk, polystyrene board, polyvinyl chloride foam plastic board.
6. sealing paste: polysulfide sealing paste, polyurethane sealing paste.

Product advantage：

After the flexible waterproof casing pipe is partially finished, the outer wall of the casing is brushed with primer (primer including camphor or cold primer oil).  The outer corrosion protection is determined by design.  If the casing part of the wall passes through the wall, in case of non-concrete wall, the concrete wall shall be used instead.  The range of pouring concrete shall be 200mm larger than the diameter of the wing ring (D6), and the casing shall be poured into the wall.  The thickness of the concrete wall where the casing passes through the pipe should not be less than 300mm.  Otherwise, the wall should be thickened on one side or on both sides.  The diameter of the thickened part * should be less than the diameter of the wing ring (D6) 200mm.  The material weight of flexible waterproof casing pipe should be calculated separately if the wall thickness L is 300mm.  T42 welding.  According to the standard atlas can be divided into: 02S404 national standard and non-standard.  National standard type waterproof casing pipe refers to material selection and production in full accordance with 02S404 or 02S312 standard atlas related to the Ministry of Construction, with strict requirements on flange thickness, wing ring thickness, pipe diameter and thickness.  Non-standard is in the shape and the general structure in line with the standard atlas, material selection of flange thickness, wing ring thickness, pipe diameter and thickness is considered to relax the requirements, strictly speaking, these are unqualified products, of course, a certain degree of relaxation of the standard will not affect the use, but excessive relaxation of the standard will affect the performance.  According to the atlas, it can be divided into 02S312 flexible waterproof casing pipe and 02S404 flexible waterproof casing pipe.  The two have different dimensions and structural forms.
