Application scope of waterproof sleeves

1. Flexible waterproof sleeves are generally suitable for areas with specific seismic protection requirements, where pipes pass through walls and are subject to vibrations and thermal expansion/contraction, or in buildings where strict waterproofing is required. Flexible sleeves are divided into two categories, A and B; category A is used in pools or when passing through interior walls. Type B is used for penetrating building exterior walls. Such as pipes connected to pressure-boosting equipment, etc. 2. Rigid sleeves are used in buildings where pipes pass through walls and are not subject to vibration or thermal expansion/contraction of the pipes. Rigid sleeves are generally classified into three types: A, B, and C. Type A is suitable for steel pipes, while types B and C are suitable for ductile iron pipes or cast iron pipes.

I’ve learned new knowledge, thank you!

Installation instructions for flexible waterproof sleeves: 1. Flexible filler materials: asphalt, hemp fibers, polystyrene boards, polyvinyl chloride foam boards. 2. Sealant: polysulfide sealant, polyurethane sealant. 3. When the sleeve passes through a wall that is not made of concrete, that section of the wall should be converted to concrete; the pouring area should be 200 larger than the diameter of the collar (D5), and the sleeve must be firmly fixed in the wall in one go. 4. The thickness of the concrete wall at the pipe penetration point should be less than 300; otherwise, one side or both sides of the wall should be thickened, with the diameter of the thickened portion being at least D5+200. 5. The weight of the waterproof sleeve is calculated based on L=300; if the wall thickness is greater than 300, it shall be calculated separately.

When waterproof sleeves pass through foundations, interior walls, floor slabs, etc., short sleeves that are larger in diameter than the outer diameter of the pipes to be installed, made of suitable materials and of appropriate length, are used at these points of passage. These sleeves help to prevent disruptions to the building structure when using waterproof sleeves for pipes under pressure, such as those for water supply or heating, and they also facilitate the installation and maintenance of such pipes. Waterproof sleeves are usually made of welded pipes; the ends of the sleeve should be mechanically cut (for example, using a toothless saw), and strict requirements are not imposed on the wall thickness. “A “waterproof sleeve” is a specially designed waterproof sleeve that is installed when pipes need to pass through buildings or structures with waterproofing requirements, such as basements.
