Stainless steel drains fittings are widely considered healthy materials. They are widely used can be recycled 100%, thus saving water resources, reducing transportation costs, reducing heat loss avoiding pollution of sanitary ware.

1. Properties of stainless steel pipe

(1) The corrosion resistance of stainless steel pipe is good. Due to the formation of a thin protective film on the surface of stainless steel, the protective film is about 3 × 10-6 mm, which is very strong hard. Even if it is damaged, as long as there is oxygen, it can prevent rust.

(2) Stainless steel pipe need worry about red water, green water other phenomena.

(3) Because the stainless steel tube is light, it is easy to handle construct to reduce the cost. Because of its corrosion resistance excellent mechanical properties, thin-walled stainless steel pipe only needs about one third of the thickness of galvanized steel pipe.

(4) Distortion. In the construction site, due to the limitations of construction site, space construction tools, the construction personnel often use the plasticity of the pipeline instead of forcing the construction according to the construction specifications. Therefore, it is necessary to consider the deformation of the connection between pipes pipe fittings.

2. Features of stainless steel pipe

(1) Life span

The service life of stainless steel pipe is very long. the analysis of the use of stainless steel abroad, as long as the service life of the building is long, the service life of the stainless steel pipe can reach 100 years, at least 70 years.

(2) Corrosion resistance

The significant advantage of stainless steel drains fittings is corrosion resistance, which is excellent in all types of piping. Because stainless steel can be passivated by oxidant, a tough compact chromium rich oxide protective film dr2o3 is formed on the surface, which can effectively prevent further oxidation reaction.

(3) Thermal insulation

The thermal conductivity of stainless steel pipe is 1 / 25 of that of copper pipe 1 / 4 of that of common steel pipe, which is especially suitable for hot water transportation. The commonly used stainless steels in the water industry are 304 316 stainless steels, which can meet the health status of most water treatment transportation habits.

(4) Strength

The tensile strength of stainless steel pipe is 2 times of steel pipe 8-10 times of plastic pipe. The strength of the material determines whether the water pipe is firm anti-collision. Due to its excellent mechanical properties, stainless steel drainage pipes accessories can withstand high water supply pressure, which can reach more than 10MPa, especially suitable for high-rise water supply.
