    Tips: Under what circumstances are sanitary butterfly valves easy to be corroded?

    Sanitary butterfly valves are mostly made of stainless steel, which has the ability to resist atmospheric oxidation, and also has the ability to resist corrosion in media containing acids, alkalis and salts. The corrosion resistance of stainless steel butterfly valves varies with the chemical composition of the stainless steel material, the use conditions and the type of environmental media. Such as the 304 stainless steel butterfly valve, in a dry and clean atmosphere, it has absolutely excellent rust and corrosion resistance. But when used in coastal areas, it will quickly rust in sea fog containing a lot of salt.

    The sanitary butterfly valve relies on a very thin, strong, dense and stable chromium-rich oxide film formed on the surface of the stainless steel material to prevent oxygen atoms from continuing to penetrate and continue to oxidize, thereby obtaining the ability to resist rust. Once the film is continuously destroyed for some reason, the oxygen atoms in the air or liquid will continue to infiltrate or the iron atoms in the metal will continue to separate out, forming loose iron oxide, and the sanitary butterfly valve will continue to be rusted.

    The chromium content of general stainless steel is generally not less than 12%, and even as high as 18%. After adding chromium and other elements to the stainless steel, the fluorine-lined butterfly valve can change the performance of the steel, and it is easier to form a dense oxide protective film on the surface of the steel, thereby greatly improving the corrosion resistance of the stainless steel butterfly valve.
