Carbon steel pipe fittings tee anti-corrosion performance
Carbon steel pipe fittings tee anti-corrosion performance, our company exports of Carbon steel pipe fittings tee, seamless tee, welding tee, inclined tee, 45 degrees of inclined tee. Advanced technology level, the complete technology testing equipment and efficient quality management, reasonable price and perfect after-sales service reputation in pipe fittings market. Welcome to login my all metal and atmospheric oxygen in the reaction, formation of oxide film on surface. Unfortunately, in the ordinary carbon steel formed on the oxidation of iron oxide to continue, kept expanding rust, eventually forming holes. Can use paint or resistant to oxidation of the metal (for example, zinc, chromium and nickel) on the plating to ensure that the surface of Carbon steel pipe fittings tee, but, as we know, the protection is only a thin film. If the cover was damaged, the following steel began to rust.
Such as chrome's corrosion resistance depends on the diameter of the Carbon steel pipe fittings tee, but because of the chromium is one part of the steel, so the protection method is not the same.
In the chromium content reaches 10.5%, atmospheric corrosion resistance increased significantly, but the chromium content is higher, although still can raise corrosion resistance, but not obvious. Reason is that with chromium alloying of steel processing, change the type of surface oxide became similar to that of pure chromium oxide is formed on the metal surface. This tight adhesion of the surface of the rich chromium oxide protection, to prevent further oxidation. This kind of extremely thin oxide layer, can see through it and diameter on the surface of the Carbon steel pipe fittings tee natural luster, make such as diameter of Carbon steel pipe fittings tee has unique surface. And, if damaged surface, exposed by the steel surface and atmospheric response to repair itself, to form the oxide "passivation membrane," continued protection.
Therefore, all the diameter of the Carbon steel pipe fittings tee element such as have a common characteristic, namely the chromium content in more than 10.5%.
We are capable of manufacturing various pipe fittings. Our main products scope: seamless elbow, tees, bends, reducers, pipe caps, forged flanges and sockets. We have been in this line for over 20 years. Our products are exported to many countries and regions, such as Southeast Asia, the Middle East, Europe and America etc. Our pipes and pipe fittings enjoy a good reputation in domestic and foreign markets. Every year, hundreds of foreign visitors and innumerable domestic visitors come to our company for business cooperation.
