The Corrosion Method of Metal Valves

Metal valve body parts are made of metallic material. Such as cast iron gate valves, carbon steel valves, forged steel globe valve and other valves. Corrosion of the valve is usually understood as the metal material suffered damage in the chemical or electrochemical environment. Due to corrosion phenomena take place in the interaction of the metal with the surrounding environment, therefore, how to separate the metal from the surrounding environment, which becomes a matter of common concern.
There are four metal valve preservation methods.
1.Make highly volatile corrosion inhibitors place the steam atmosphere.
2.The use of blocked water and alcohol solution.
3.Apply the anti-corrosion materials on the surface of valve and its components.
4.Make blocked thin layer apply to the valve and its components.
