02S404-type flexible waterproof casing Description:
1 Flexible packing materials: asphalt, flax, polystyrene board, PVC foam board.
2. Sealant: polysulfide sealant, polyurethane close to the cream
3 casing wall at the case of non-concrete walls, concrete walls should be of local use, its scope should be Bizart casting ring diameter (D5) large 200 and a water pipe must be secured to the wall.
4. Wear a tube of concrete thickness of the wall should be less than 300, or the side wall should be thick or thicker on both sides, thicker part of the diameter of at least D5 +200.
5. casing weight to L = 300 is calculated as thickness of the wall greater than 300, should be calculated.
1 What is the flexible waterproof casing
Flexible waterproof casing is applied to pipe through the wall of the office by a vibration or a close-knit structure of the water requirements of the hardware fittings, general manufacturers is based on the design of the Research Institute of Building Sciences S312, 02S404 standard atlas manufacturing. Flexible waterproof casing wall at the wall, in case of non-use of concrete walls should be concrete and must be solidified in a casing wall; flexible waterproof casing facilities are widely used in construction, chemical, steel, water, sewage treatment other units.
Generally do use the pool to the casing when it is the pipe leading to the pool of channels. But ordinary casing is difficult to seal, so there will be between the casing and the pipe from leaking between the casing and the wall is also easy to leak. Only waterproof casing, then solve the leakage between the casing and the wall, can not solve the seal between the casing and the pipe, flexible waterproof casing just to solve two problems.
Casing can be divided into: normal casing - to use the pipeline than 2-4 cm thick, fixed to the wall or board, the pipeline from through. Flexible tube - that is, between the casing and the pipe sealed with a flexible timber sealing effect play. Steel casing - that is, between the steel casing and the pipe material to seal the sealing effect. Waterproof casing - the casing is used to prevent liquid leakage or the environment is leaking into the place (such as pools, septic tanks, basements, etc.) is increasing in the outer casing of not less than a lap water wings, so set tube when pouring in the wall as a whole, will not factor the expansion and contraction cracks and leaks.
(2) Classification of flexible waterproof casing
Atlas can be divided in accordance with the standard: national standard and non-standard. National standard waterproof casing is in full accordance with the Ministry of Construction or related 02S404 02S312 standard atlas selection and production, the thickness of the flange, ring wing thickness, diameter and thickness, there are stringent requirements. Non-standard is in the shape and structure of the standard atlas is probably the case, when the selection of the thickness of the flange, ring wing thickness, diameter and thickness that the relaxation of requirements, strictly speaking, these are substandard products, of course, a certain extent of relaxation of standards do not affect the use, but too much criteria will affect the performance back.
According to Atlas can be divided into: S312-type flexible waterproof casing and 02S404-type flexible waterproof casing. In both dimensions, the structure has a different form.
3 flexible waterproof casing specifications
DN50mm-DN3200mm
4 rigid waterproof casing and flexible waterproof casing difference
Steel casing is waterproof plus rigid wing ring (steel ring set made on the pipe), installed on the walls (mostly concrete walls), for general pipeline wall, the wall of water is conducive to;
In addition to the external wing of flexible waterproof casing ring, there are files within the circle and the like, Falanneisi, have packages to sell, but also their processing needs for a shock absorber pipe, such as connecting pipes and pumps to wear When the wall.
Mainly used in place is not as flexible waterproof casing is mainly used in air defense walls, pools and other demanding areas, rigid waterproof casing pipe is generally used in basements and other locations required to wear a pipe.
Home through underground pipes from the external walls of buildings required to install rigid waterproof casing.
Wall (pool, board, etc.) of the casing. Divided into rigid and flexible two. After installation, the amount of deformation allowed --- flexible; allowed deformation - the rigidity.
