As we all know, the corrosion damage of metal has a considerable impact on the effect period, reliability and service life of the valve. The effect of mechanical and corrosion factors on the metal greatly increases the total amount of wear to the touch. Valve in the operation process, the friction of the appearance of the total amount of wear. During the operation of the valve, the appearance of friction causes wear and damage as a result of simultaneous mechanical effects and chemical or electrochemical interactions between metals and the environment. For the valve, the working climate conditions of the pipeline clutter; oil, natural gas and oil layer water and other media in the presence of hydrogen sulfide, carbon dioxide and certain organic acids to the metal appearance of the damage increased, thus quickly lost the ability to work.
The corrosion of the valve is usually understood as the damage of the metal material of the valve under the effect of chemical or electrochemical environment. Because the corrosion phenomenon is presented in the mutual effect of metal and the surrounding environment, therefore, how to block the metal from the surrounding environment or use more non-metallic composition data has become a common concern.
Because the chemical corrosion of metals depends on the temperature, the mechanical load of friction parts, the stability of sulfides contained in smooth materials and their acid resistance, the duration of medium touch, the catalytic effect of metals on the nitriding process, the conversion speed of molecules of corrosive substances to metals, and so on. Therefore, the metal valve anti-corrosion measures (or measures) and the application of the composition of the valve, has become one of the themes of the valve occupation research.
Anticorrosion of metal valves can be understood as coating a maintenance layer (such as paint, pigment, smooth material, etc.) on metal valves to prevent corrosion, so that the valves are not corroded in the production, preservation, transportation or in the process of their use. Metal valve anticorrosion method depends on the required maintenance period, delivery and preservation conditions, valve structure characteristics and information, of course, the habit of considering the economic effect of anti-corrosion.
There are four main ways to prevent corrosion of metal valves and their parts:
1. Put the volatile corrosion inhibitor into the vapor atmosphere (wrap it with a barrier paper, blow the inhibited air through the product chamber, etc.).
2, the use of water and alcohol solution is blocked.
3. Apply a thin layer of anti-corrosion (maintenance) data to the appearance of the valve and its parts.
4, will be the resistance of the film or polymer thin layer coated on the valve and its parts appearance.
