Many people know about 304 stainless steel. This is a food grade stainless steel. Many kitchen products are made of 304 stainless steel. 304 food grade is the raw material of Chinese stainless steel sink. Why does China Stainless Steel Sink use 304 stainless steel?
Stainless steel tubes have the longest life. From the analysis of the use of stainless steel from abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, as long as the service life of the building.
2, corrosion resistance
One of the most outstanding advantages of stainless steel tubing is its excellent corrosion resistance, which is the best among all kinds of tubing. Since the stainless steel can be passivated with the oxidizing agent, a tough and dense chromium-rich oxide protective film Dr2O3 is formed on the surface, which effectively prevents further oxidation reaction. Other metal tubes, such as galvanized water pipes and copper pipes, have little passivation capability. This is the key reason why the corrosion resistance of galvanized copper pipes is much lower than that of stainless steel pipes. Stainless steel does not have uniform corrosion like carbon steel and does not require a protective coating when used; stainless steel water pipes have no restrictions on the chemical composition of water because stainless steel is very good in water containing various oxygen contents, temperatures, pH and hardness. Corrosion resistance; stainless steel water pipes can withstand high flow rates, even at flow rates greater than 40 m / s, still maintain a very low corrosion rate, no more than 0.003 mm / year, especially suitable for high-rise water supply. Stainless steel usually does not undergo localized corrosion. 304 stainless steel can withstand up to 200 ppm of chloride and 316 stainless steel can withstand up to 1000 ppm of chloride. This conclusion is based on exposure data and has been proven by experience. The coefficient of thermal expansion of the stainless steel tube is similar to the coefficient of thermal expansion of the copper tube, which is 1.5 times that of the ordinary steel tube. It has the characteristics of slow expansion and contraction compared to stainless steel tubes.
3, thermal insulation
The thermal conductivity of stainless steel pipes is 1/25 of that of copper pipes, which is 1/4 of ordinary steel pipes and is especially suitable for hot water transportation. The most commonly used stainless steels in the water industry are 316 and 304 stainless steel plates for most water treatment and storage conditions.
The tensile strength of 304 stainless steel pipe is twice that of steel pipe, which is 8~10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong and collision-proof, safe and reliable. Safety and reliability are the most important requirements for building water supply. In the case of external impact, the possibility of leakage of stainless steel water pipes is very small. The working pressure of the high-rise water supply system is generally greater than 0.6Mpa; the pipeline pressure is higher. Due to its excellent mechanical properties, thin-walled stainless steel pipes can withstand high water supply pressures of up to 10 MPa, making them ideal for high-rise water supply.
