Corrosion of metal needle valve

Corrosion of a needle valve is generally understood to be the damage of a needle valve metal material under the action of a chemical or electrochemical environment. Since the "corrosion" phenomenon occurs in the spontaneous interaction between the metal and the surrounding environment, how to isolate the metal from the surrounding environment or use more non-metallic synthetic materials is the focus of corrosion prevention.

Needle valve body (including the valve cover), occupies most of the weight of the valve, but also in regular contact with the medium, so the selection valves, often from the body material.

The corrosion of the valve body is not only two forms, namely chemical corrosion and electrochemical corrosion. Its corrosion rate is determined by the temperature, pressure, chemical properties of the medium and the corrosion resistance of the valve body material. Corrosion speed can be divided into six:
1, complete corrosion resistance: corrosion rate is less than 0.001 mm / year;
2, extreme corrosion resistance: corrosion rate 0.001 to 0.01 mm / year;
3, corrosion resistance: corrosion rate of 0.01 to 0.1 mm / year;
4, still resistant to corrosion: corrosion rate of 0.1 to 1.0 mm / year;
5, poor corrosion resistance: corrosion rate of 1.0 to 10 mm / year;
6, non-corrosion resistance: corrosion rate is greater than 10 mm / year.

Peeled garlic is a kind of deep processing product of garlic, which is widely concerned and popular by many countries. In general, the production process of peeled garlic requires 13 steps, include raw material acceptance, soaking, peeling, secondary peeling, classifying, inspecting, disinfecting, cleaning, dehydrating,quick-freezing, packing,mental detecting and refrigerating.
