Understanding Of Stainless Steel Sanitary Valves And Fittings
Understanding of Sanitary Valve
1. Sanitary large-diameter thin-walled stainless steel pipes and fittings can be recycled, saving water resources, reducing transportation costs, reducing heat loss, and avoiding sanitary ware pollution.
2. Sanitary large-diameter thin-walled stainless steel pipes and fittings have a long service life. According to the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, and there are also 70 years, which is as long as the life of the building.

3. One of the outstanding advantages of sanitary large-diameter thin-walled stainless steel pipes and fittings is its excellent corrosion resistance, which is the best among various pipes. Because stainless steel can be passivated with oxidants, a tough and dense chromium-rich oxide protective film Dr2O3 is formed on the surface to prevent further oxidation reactions. Other metal pipes, such as galvanized water pipes and copper pipes, have very small passivation capabilities. This is the key reason why the corrosion resistance of galvanized copper pipes is far inferior to that of stainless steel pipes.
4. The thermal conductivity of sanitary large-diameter thin-walled stainless steel pipes and fittings is 1/25 of that of copper pipes and 1/4 of that of ordinary steel pipes, which are particularly suitable for hot water transportation. The stainless steel commonly used in the water industry is 304 and 316 stainless steel, which can meet most water treatment and transportation conditions.

Stainless steel will not corrode uniformly like carbon steel, and no protective coating is required when used; stainless steel water pipes have no restrictions on the chemical composition of water, because stainless steel has good corrosion resistance in water with various oxygen contents, temperatures, PH and hardness; stainless steel water pipes can withstand very high flow rates, even if the flow rate is greater than 40 meters/second, it still maintains an extremely low corrosion rate of no more than 0.003 mm/year, which is particularly suitable for high-rise water supply.
