The seamless steel pipe is a layer of ultra-thin, firm and stable chromium-rich oxide film (protective film) formed on its surface to prevent the re-infiltration and re-oxidation of oxygen atoms, and obtain the professional ability to resist rust. Once there are various reasons, such plastic films are continuously damaged, oxygen atoms in the gas or liquid will continue to infiltrate or iron atoms in the metal composite material will continue to separate out, resulting in loose chemical substances, and the surface of the metal material will be continuously damaged. Rust. The following will give you a detailed explanation of the reasons for corrosion of seamless pipes and preventive measures.
2. The surface of the seamless tube adheres to the organic juice (such as vegetables, fried noodles, sputum, etc.), which forms sodium citrate in the presence of ice and oxygen, and the long-term corrosion of sodium citrate on the surface of metal materials.
4. In the air with air pollution (such as gas containing a lot of potassium thiocyanate, carbon oxide, and sulfur oxide), when it encounters condensed water, it will cause the liquid point of sulfuric acid, sodium cyanide, and glacial acetic acid, resulting in chemical corrosion.
