1. Life

Stainless steel pipe The material has a long service life. Based on the analysis of the use of stainless steel abroad, Stainless steel water pipe Its service life can reach 100 years, at least 70 years, which is as long as the service life of buildings.

2. Corrosion resistance

One of the outstanding advantages of stainless steel drainage pipes and fittings is their excellent corrosion resistance, which is excellent among all kinds of pipes. Because stainless steel can passivate with oxidant, a tough and dense chromium rich oxide protective film Dr2O3 is formed on the surface, which can prevent further oxidation reaction. Other metal pipes, such as galvanized water pipes and copper pipes, have little passivation capacity, which is the key reason why the corrosion resistance of galvanized copper pipes is far less than that of stainless steel pipes.

3. Heat resistance and insulation

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

4. Strength

The tensile strength of 304 stainless steel pipe is twice that of steel pipe and 8-10 times that of plastic pipe. The strength of the material determines whether the water pipe is firm, collision resistant and reliable. Stainless steel drainage pipes and pipe fittings can withstand very high water supply pressure due to their excellent mechanical properties, which can reach more than 10Mpa, especially suitable for water supply of high-rise buildings.
