Why is stainless steel tube called 21 century true green pipe material?
2021-06-11
1. Service life
Stainless steel pipe has a long service life. From the analysis of the stainless steel use situation abroad, the service life of stainless steel pipe can reach 100 years, at least there are 70 years, as long as the life of the building.
2. Corrosion resistance
One of the advantages of stainless steel drains and fittings is their excellent corrosion resistance, which is excellent among all kinds of pipes. Because stainless steel can be passivated with oxidizing agents, forming a tough and dense layer of chromium oxide protective film DR2O3 on the surface, effectively preventing further oxidation reaction. And other metal pipe, such as galvanized water pipe, copper pipe passivation capacity is very small, which is the key reason for the corrosion resistance of galvanized copper pipe is far less than that of stainless steel pipe.
3. Heat-resisting and heat preservation
The thermal conductivity of stainless steel pipe is 1/25 of copper pipe, 1/4 of ordinary steel pipe, especially suitable for hot water transportation. Stainless steel 304 and 316 are commonly used in the water industry, which can meet most water treatment and transportation conditions.
4. Tensile strength
The tensile strength of 304 stainless steel pipe is 2 times that of steel pipe and 8~10 times that of plastic pipe. The strength of the material determines whether the water pipe is firm and crash-resistant, safe and reliable. Stainless steel pipe and pipe fittings due to excellent mechanical properties, can withstand high water supply pressure, up to more than 10MPa, especially suitable for high-rise water supply.
