Follow the skills, the industrial production of high temperature and high pressure, low temperature, high vacuum, corrosive, radioactive, toxic, flammable and explosive increasing contour parameters of mixed and disorderly conditions, then the Industrial Valves use security, and the function of using life, etc, puts forward higher and more stringent requirements. As a result of 'corrosion' phenomena appeared in the metal and the surrounding environment of spontaneous interaction, how the metal with the surrounding environment or more isolated from the use of non-metallic composite material, is the key point of anti-corrosion. The corrosion of the Industrial Valves, is generally understood as the valve metal materials in the chemical or electrochemical environment under the action of the damage. Body corrosion, comes in two forms, namely, chemical corrosion and electrochemical corrosion. The corrosion rate of it depends on the medium temperature, pressure, chemical properties and corrosion resistance of the body material. Corrosion velocity can be divided into six: 1, complete corrosion: corrosion speed below zero. 001 mm/year; 2, corrosion resistant, corrosion speed of 0. 001 to 0. 01 mm/year; 3, corrosion resistant, corrosion speed of 0. To 0 01. 1 mm/year; 4, it is corrosion resistant, corrosion speed of 0. 1 to 1. 0 mm/year; 1 5, poor corrosion resistance: the corrosion rate. 0 to 10 mm/year; 6, no corrosion, corrosion speed is greater than 10 mm/year. Although body corrosion data is very rich, but can choose well, or not easy thing, because the problem of corrosion is very complex, so the body corrosion protection methods are there? First, choose the right to choose material. Choose the difficulty of the body material, also is not only considered the corrosion problem, at the same time must consider pressure and heat-resistant ability, economically reasonable, buy whether factors such as easily. Followed by lining measures, such as lining, lining aluminum, lead lining engineering plastics, lining natural rubber and various synthetic rubber, etc. Such as medium conditions permit, it is a way to save. Again, in the case of pressure, temperature is not high, do the Industrial Valves body with nonmetal material, often can effectively control the corrosion. In addition, the body surface by atmospheric corrosion, general steel material is to brush paint protection.
