Introduction: Stainless steel flexible waterproof casing can be divided into two types: stainless steel flexible waterproof casing and stainless steel flexible waterproof casing. The rigid waterproof casing embedded in the pipeline through the floor and roof can reasonably prevent the leakage of the floor, which is widely used in the building water supply and drainage engineering; drinking water, industrial plants

Flexible stainless steel Waterproof casing Can be divided into: stainless steel Flexible waterproof casing And stainless steel flexible waterproof casing. Pipeline passing through floor and roof embedded Rigid waterproof casing , which can reasonably prevent floor leakage, is widely used in building water supply and drainage engineering; drinking water, industrial plant, civil air defense equipment, sewage well and waste water pool of sewage treatment plant need pipelines to cross according to red brick wall, and need to be able to move up and down, then flexible waterproof casing is needed. When these two kinds of waterproof casing are used to contact with corrosive medium, the design staff should base on it According to the medium characteristics and anti-corrosion requirements, the available corrosion-resistant materials - 316L stainless steel, 304 stainless steel, 201 stainless steel and so on are selected.
The layout of water supply pipe and waterproof sleeve in high-rise building should ensure water supply and good hydraulic conditions. In addition, the installation of waterproof casing can prevent the application of building from being affected and beautiful, which is convenient for maintenance, management and repair, and economic and reasonable. Because the pressure of municipal pipe network is used to supply water directly in the low area, the lead-in pipe is connected to the domestic water storage tank and fire water storage tank respectively after passing through the water meter connection point. The low area water supply system uses the municipal pipe network pressure to supply water directly, and adopts the water supply method of downward and upward supply. The branch pipe network and horizontal main pipe are laid in the ceiling of the first floor underground. The water supply riser is arranged in the pipe well or wall tank as far as possible. Some of the risers arranged at the corner of the wall and the side of the column can be decorated by civil engineering.
The flexible water-proof casing water supply system adopts district water supply, and the municipal pipe network supplies water directly from the first floor to the second floor of the low area; the second to the twelfth floor of the central area and the twelfth to twenty second floor of the high area adopt the frequency conversion water supply without air pressure. The drainage equipment adopts the combined system of sewage and sewage, and the bottom layer is separately discharged. The drainage riser is equipped with an extended top vent pipe, and the waste water is directly discharged to the municipal wastewater pipe network. The fire control system is divided into fire hydrant water supply system and automatic sprinkler fire system, in which the fire hydrant system adopts water pump water supply system.
