A, pay attention to the metal valve corrosion problems:
The corrosion of the valve, the valve is often understood as metal materials in chemical or electrochemical environment under the effects of all the damage. As a result of "corrosion" phenomenon appears in the metal and the surrounding environment of spontaneous interaction, so, how will the metal and the surrounding environment phase isolation or more use non-metallic synthetic materials, is a common concern of the people. As is known to all, metal corrosion damage to the valve function period, reliability and service life have considerable influence. Mechanical and corrosion effect factors on the role of the metal contact surface greatly increase the total amount of wear. The valve in the operating process, the surface of the friction in wear. The valve in the operating process, the surface of the friction at the same time because of the role of the mechanical and metal and environmental chemical or electrochemical interaction of the result of wear and tear. In terms of the valve, the pipe work climate conditions of the complex. Oil, gas and oil reservoir water medium such as h2s and co2 and some organic acids the appearance of the metal surface damage increase, thus rapidly lose working ability.
As a result of the metal chemical corrosion depends on temperature, friction parts mechanical load, lubricating material contain sulfide and acid resistant stability and medium contact duration and metal to nitriding process catalysis, corrosion erosion sex the molecules of a material to metal conversion speed and so on. Therefore, metal valve anti-corrosion methods (or measures) and synthetic materials, the application of the valve, and become the valve industry one of the themes of research.
Metal valve anticorrosion, and can be understood as the metal valve coating to protect its from corrosion conditions cover (such as paint, paint, lubricating material, etc.), so that the valve whether in manufacturing, storage, transportation or in the use of the whole process are not corrode. Metal valve anti-corrosion methods depends on the requirements of the protection period, transportation and preservation conditions, valve structure characteristics and materials, of course, to adapt to consider remove corrosion economic effect.
Metal valve and its components anticorrosive method mainly has four kinds:
1, will be volatile corrosion inhibitor in steam atmosphere (with resistance change paper packages, blows inhibition air through the products chamber, etc.).
2, to use resistance change of water and alcohol solution.
3, the corrosion (protection) material thin layer on the surface of the valve and its components.
4, will be resistance change of film or polymer thin layer on the surface of the valve and its components.
(note: the valve manufacturing enterprises, widely used lubricating material and water resistance change solution flow to corrosion.
Second, how to solve the metal valve anticorrosion problem:
