Hardware casing flexible waterproof casing is generally suitable for pipe through the wall by the vibration or tight waterproofing request of the structure, casing local processing completed, in the outer wall are painted again (primer including camphor or cold base oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The two are mainly used in the center of different, flexible waterproof casing is mainly used in the civil defense wall, pool and other requests are very high central, rigid waterproof casing commonly used in the open room and other pipelines need to wear pipe position.

Flexible waterproof casing is suitable for pipe through the wall by the vibration or tight waterproofing request of the structure of the metal pipe fittings, ordinary consumer enterprises are based on the Architectural Science Research Institute of the Development and design of the S312, 02S404 Standard Atlas Manufacturing. Flexible waterproof casing through the walls of the wall, such as in the case of non-concrete should be replaced with concrete walls, and the casing must be solidified once in the wall; flexible waterproof casing is commonly used in construction, chemical, steel, tap water, sewage disposal and other units.
Rigid waterproof casing is steel pipe plus wing ring (steel plate made of ring sleeve on the steel pipe), installed in the wall (mostly concrete wall), used for ordinary pipe through the wall, conducive to the waterproof wall, and flexible waterproof casing in addition to the external wing ring, the interior also has gear and so on, Frannes, there are complete sets of sales, can also be processed Such as when the pipe connected with the pump is worn through the wall. Whether it is flexible waterproof casing or rigid waterproof casing is used for piping through the walls of buildings subject to vibration or tight waterproofing requests, often used in construction, chemical, steel, tap water, sewage disposal and other units.

Commonly used waterproof casing is divided into two types of rigidity and flexibility, selection should pay attention to: waterproof casing is based on the Architectural Science Research Institute of the Development and design of S312, 02S404 Standard Atlas Manufacturing. Rigid waterproof casing is suitable for drinking water pool waterproof casing device, after the end of asbestos cement filling to stop, fill the seal paste, should ensure that the contact surface in the seam without rust, lacquer skin, dirt, and clean, boring. Flexible waterproof casing is generally suitable for pipe through the wall by the vibration or tight waterproofing request of the structure; wear walls at the wall, in case of non-concrete should be replaced with concrete walls, and the casing must be solidified once in the wall; waterproof casing applied to construction, chemical, steel, tap water, sewage disposal and other units.
Waterproof Casing Sealing Data:
1. Flexible filler data: Bitumen, hemp wire, polystyrene board, PVC foam board.
2. Sealing paste: Sulfur sealant paste, polyurethane dense pair cream.
3. Casing through the wall in the case of non-concrete walls, should be partially switched to concrete walls, its pouring range should be biyi ring diameter (D5) Large 200, and the casing must be doused once in the wall.
4. The concrete wall thickness of the pipe should be less than 300, otherwise the wall should be thickened or thickened on both sides, thickened local diameter of at least D5+200.
5. When the weight of the casing is calculated in L=300, if the wall thickness is greater than 300, it should be calculated separately.
When the water surface for corrosive media, can be used to block the gap sealing casing through the wall in case of non-concrete walls, should be partially switched to concrete walls, its pouring range should be biyi ring diameter (D5) 200, and the casing must be poured into the wall at once. The concrete wall thickness of the pipe shall not be less than 300, otherwise the wall shall be thickened or thickened on either side. The thickened local diameter is at least D5+200. The weight of the metal casing is calculated in L=300, and should be calculated separately if the wall thickness is greater than 300
