Advantages of Stainless Steel Pipe

Advantages of Stainless Steel Pipe

1, With outstanding mechanical features, superior wear resistance, surface thin and dense chromium-rich oxide film, making the stainless steel tube in all water, including soft water, have outstanding corrosion resistance, even if the use of buried there excellent corrosion resistance. Stainless steel pipe(ss pipe) can be filled with high-speed water erosion of up to 30m / s. It is used in the diversion stainless steel pipe of the high-head power plant. The water velocity at the end of the nozzle reaches 60m / s or above, and there is still more than 100 years of service life.

2, Tensile strength greater than 530 N / mm, is 2 times the galvanized pipe, 3-4 times the brass, PPR pipe 8-10 times, and has outstanding ductility and resistance, help to save water, Surface is beautiful, clean, fashion, 100% recyclable, safe and clean, good temperature resistance, good thermal insulation, smooth wall water resistance is small, able to long-term safety at -270 ℃ -400 ℃ temperature Homework, whether it is high temperature or low temperature, will not separate harmful substances, data function properly and safely.

3, The insulation function is 24 times the copper tube, reducing heat loss, especially suitable for hot water transport, will not form an environmental pollution, green, conducive to sustainable development, and stainless steel scrap also has great economic value, safety No poison, no corrosion and exudate, no smell or turbid doubt, will not form secondary pollution of water quality, insist on pure and clean water, clean and safe to ensure thorough.

Stainless steel pipe can not only play an excellent supporting role, and can carry long-distance liquid material, gaseous material transmission, in order to improve the power of industrial production, make people's days more convenient and comfortable, stainless steel pipe is very high cost performance, suitable for a wide range of infrastructure construction operations, it is very common in the days.

Why is stainless steel corrosion resistant?

All metals react with oxygen in the atmosphere to form an oxide film on their surface. Unfortunately, the iron oxide that forms on plain carbon steel continues to oxidize, causing the rust to expand and eventually form holes. The carbon steel surface can be protected by paint or electroplating with oxidation-resistant metals such as zinc, nickel and chromium, but, as is known, this protection is only a film. If the protective layer is damaged, the steel underneath will begin to rust. The corrosion resistance of stainless steel depends on chromium, but because chromium is one of the components of steel, the protection methods are different. When the chromium addition reaches 10.5%, the corrosion resistance of stainless steel depends on chromium, but because chromium is one of the components of steel, the protection method is different. The performance is significantly increased, but when the chromium content is higher, although the corrosion resistance of stainless steel can still be improved, it is not obvious. The reason is that when steel is alloyed with chromium, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal.

This tightly adhered chromium-rich oxide protects the surface from further oxidation. This oxide layer is extremely thin, through which the natural luster of the steel surface can be seen, giving stainless steel a unique surface. Moreover, if the surface is damaged, the exposed steel surface will react with the atmosphere to repair itself, reforming the oxide "passivation film" and continuing to play a protective role. Therefore, all stainless steel elements have a common characteristic, that is, the chromium content is above 10.5%. The term "stainless steel" does not simply refer to one type of stainless steel, but to more than one hundred types of industrial stainless steel, each of which has been developed to perform well in its specific application area. The key to success is first to understand the application and then determine the correct type of steel.
