What are the requirements of flexible waterproof casing?
Flexible waterproof casing of raw materials as far as possible qualified, flexible waterproof casing 02S404, with product certification, flexible waterproof casing, program design pending special requirements, try to meet the requirements of the design program. Appearance inspection flexible waterproof casing wall thickness uniform, welding welding uniform, no cracking, burr sand hole, prick and concave flat and other defects. The industrial coating of stainless steel welding rod is uniform, solid and without cracks.
Requirements of flexible waterproof casing;
Flexible waterproof casing is generally suitable for passing through the wall where there is oscillation or close waterproofing requirements of the structure.
After the processing of the casing is completed, the outer wall of the casing is painted with primer once. The outer layer of anti-corrosion is decided by planning.
Casing through the wall of the wall, such as non-concrete walls should be replaced with concrete walls, the scale of its pouring concrete should be larger than the diameter of the wing ring (D6) 200mm, and the casing will be poured and fixed in the wall.
The concrete wall thickness of the pipe penetration should be not less than 300mm, otherwise the wall should be thickened on one side or both ends. The diameter of the thickened part should be smaller than the diameter of the wing ring (D6) 200mm
When the water surface is corrosive media, the gap can be sealed with blocking materials.
