Name: steel flexible waterproof casing
       flexible waterproof casing generally applies to pipe through the wall of the office or close by the vibration of structures in water requirements; generally applicable to rigid waterproof casing pipe through the wall of the structure at the general water requirements ; flexible and rigid 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; waterproof casing applied to construction, chemical, steel, water, sewage treatment other units.
Rigid waterproof casing and the difference between flexible waterproof casing
       is rigid waterproof casing plus wing steel ring (the ring sets of steel to do the pipe), installed on the walls (mostly concrete walls), for general pipeline wall, which will help wall of water;
   flexible waterproof casing in addition to the external wing 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 and pump when the connection pipe 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. Steel flexible waterproof casing Description:     1, the map dimensions are in millimeters to the meter.     2, flexible waterproof casing is generally through the walls of the office by a vibration or tight waterproof requirements structures.     3, the casing part of the process is completed, both in its exterior paint brush again (including Zhang Dan or cold primer base oil). The outer layer of corrosion by design.     4, through the wall of the casing wall, in case of non-use of concrete walls should be concrete walls, pouring concrete, its scope should fly wing to wing ring diameter (D6) large 200mm, and must be poured solid with the casing wall.     5, the wear of the concrete pipe at the thickness of the wall should be not less than 300mm or thicker side or both sides of the wall thickening. Thicker part of the diameter of the smallest ring diameter should be Nina (D6) 200mm     6, is based on the weight of casing material thickness of the wall is 300mm L should be calculated.     7, the casing parts welding materials, materials with the A3, T42 welding. 

A type of steel flexible waterproof casing

Description:
1, when the positive side of the corrosive medium, sealing material can be used to block the gap.
2, the 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) big 200, and a water pipe must be secured to the wall.
3, the wear of concrete pipe thickness of the wall should be not 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.
4, casing weight to L = 300 terms, such as thickness of the wall is greater than 300, should be calculated.

B-type steel flexible waterproof casing

 Description:
1, flexible packing materials: asphalt flax, polystyrene board, PVC foam board.
2, sealant: polysulfide sealant, polyurethane sealant.
3, the 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) big 200, and a water pipe must be secured to the wall.
4, wearing a tube of concrete thickness of the wall should be not 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 terms, such as thickness of the wall is greater than 300, should be calculated.
