Industrial stainless steel tube maintenance?

Release time:2021.08.09 Announcer: Hits:

Industrial stainless steel tubes are widely used in various industrial sites because of their excellent corrosion resistance, but many people are not very familiar with the properties of stainless steel, and little is known about the maintenance of stainless steel industrial tubes. So how to maintain the industrial stainless steel pipe?

Many people think that stainless steel does not rust, but in fact, stainless steel has good corrosion resistance. The reason is that because the passivated film is formed on the surface, it exists in the form of more stable oxides. That is, stainless steel has different degrees of oxidation according to the conditions of use, but is eventually oxidized, so this phenomenon is called corrosion. All metal surfaces exposed to corrosive environments undergo electrochemical or chemical reactions and are uniformly corroded.

The weak corrosion resistance of the passivation film on the surface of stainless steel industrial pipeline will form holes due to the self-excited reaction, and the strong corrosive liquid will form near the chloride ion, so as to accelerate the corrosion reaction. In addition, there are intergranular corrosion cracks in stainless steel, and all the cracks can destroy the passivation film on the surface of stainless steel. Therefore, the stainless steel surface should be cleaned and maintained regularly to maintain the colored surface and extend its service life.
