Industrial stainless steel pipes are widely used in various industrial sites due to their excellent corrosion resistance. However, many people are not very familiar with the performance of stainless steel and know very little about the maintenance of stainless steel industrial pipes. So how to maintain industrial stainless steel pipes?
Many people think that stainless steel will not rust, but in fact, stainless steel has good corrosion resistance. The reason is that since the passivation film is formed on the surface, it exists as a more stable oxide. That is, stainless steel has a different degree of oxidation according to usage conditions, but is eventually oxidized, so this phenomenon is called corrosion. All metal surfaces exposed to corrosive environments will undergo electrochemical or chemical reactions and will be uniformly corroded.
The weak corrosion resistance of the passive film on the surface of the stainless steel industrial pipeline will form pores due to the self-excited reaction, and a strong corrosive liquid will be formed near the chloride ion, thereby accelerating the corrosion reaction. In addition, there are intergranular corrosion cracks in the stainless steel, and all the cracks have a destructive effect on the passive film on the surface of the stainless steel. Therefore, the stainless steel surface should be cleaned and maintained regularly to maintain the colorful surface and prolong its service life.
