The following introduces some factors that need to be considered in the selection of building water supply pipes. The life of the building: the life of the general high-rise building is set at 100 years, and the multi-storey building is set at long-term durability according to standards, and the selected pipes should be matched with it. It is very difficult to replace the water supply pipes in the houses that have been moved in, and the water supply must be cut off to destroy the decoration; the water delivery temperature: it can be divided into suitable cold water pipes and hot water pipes; Water, choose different pipes for different water quality, and generally choose PPR pipes for drinking water, which has the characteristics of non-toxic, hygienic, thermal insulation, energy saving, and good heat resistance. Recyclable (environmentally friendly), weldable, flexible, and thermally conductive. Laying method: There are open and dark applications, and the exposed layers are exposed indoors and outdoors. Plastic water supply pipes should not be exposed outdoors, because they are easily exposed to sunlight and ultraviolet rays and accelerate aging. Some soft plastic pipes are not suitable for indoor open application, and are bent and deformed by thermal expansion and cold contraction. Concealed laying in the tube hole, wall embedded in the ceiling, or buried in the leveling layer, aluminum alloy lined with plastic pipe, should not be buried or embedded in the wall due to cement corrosion.
