1 Life
Stainless steel pipes have the longest service life. From the analysis of the service situation of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, which is as long as the service life of buildings.
2. Corrosion resistance
One of the most outstanding advantages of stainless steel pipe is its excellent corrosion resistance, and it is a leader among all kinds of pipes. Because stainless steel can be passivated by oxidant, a tough and compact chromium-rich oxide protective film Dr2O3 is formed on the surface, which effectively prevents further oxidation reaction. However, other metal pipes, such as galvanized water pipes and copper pipes, have little passivation ability, which is the key reason why the corrosion resistance of galvanized water pipes and copper pipes is far less than that of stainless steel pipes.
3, heat resistance and heat preservation
The thermal conductivity of stainless steel pipe is 1/25 of copper pipe and 1/4 of ordinary steel pipe, which is especially suitable for hot water transportation. ? The most commonly used stainless steels in water industry are 304 and 3 16 stainless steels, which can meet most water treatment and transportation conditions.
4. Strength
The strength of the material determines whether the water pipe is strong and collision-resistant, safe and reliable. Safety and reliability are the most important requirements for building water supply. Under the impact of external force, the possibility of water leakage of stainless steel water pipes is extremely small. The working pressure of water supply system in high-rise buildings is generally greater than 0.6Mpa, which requires higher pressure on pipelines. Thin-walled stainless steel pipe can withstand high water supply pressure, and because of its excellent mechanical properties, it can reach more than 10Mpa, especially suitable for high-rise water supply.
The above is an analysis of the standards and advantages of threaded pipe fittings. You can learn more about them. As for the manufacturer and quotation, it is for your reference only. After all, there are differences in different regions. You can call for advice before buying. From the above, it can be seen that threaded pipe fittings have long service life, good corrosion resistance and excellent heat-resistant and heat-insulating properties, and are very suitable for water industry. But in the usual process, we should pay more attention to maintenance to prolong the service life and reduce the cost.
