Stainless steel seamless pipes are now used more in life. Many water transportation and gas transportation are carried out by stainless steel seamless pipes, and its role is more than that, but long-term use will also If it affects it, we also need better steps to maintain it in the maintenance process. Let's talk about how to maintain the stainless steel seamless pipe.
The use of stainless steel seamless pipes has become more extensive with the development of the economy. People are closely related to stainless steel in their daily lives, but many people do not know much about the performance of stainless steel, and they know less about the maintenance of stainless steel seamless pipes. . Many people think that stainless steel does not rust. In fact, the reason for the good corrosion resistance of stainless steel is that a passivation film is formed on the surface, which exists in the form of a more stable oxide in nature. That is to say, although stainless steel has different degrees of oxidation according to different conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion; all the metal surfaces exposed in the corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded. Among them, the corrosion resistance of 316L stainless steel seamless pipe is better than that of other materials, and it has excellent resistance to stress corrosion cracking; stress corrosion is a prominent problem that is difficult to solve for ordinary austenitic stainless steel pipes.
The corrosion resistance and heat resistance of stainless steel seamless pipes depend on chromium, but since chromium is one of the components of steel, the protection methods of high temperature stainless steel seamless pipes are also different. If the surface is damaged, the exposed steel surface of the high temperature resistant stainless steel seamless pipe reacts with the atmosphere to repair itself, forming a "film" and continuing to play a protective role.
The parts with weak corrosion resistance in the passive film on the surface of the stainless steel seamless pipe will form a pitting reaction due to the self-excited reaction, forming small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution and accelerating the corrosion reaction speed; and intergranular corrosion cracking inside the stainless steel, all of which have a damaging effect on the passive film on the surface of the stainless steel plate. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life.
