Valve handwheel anticorrosion measures

1. the use of non-metallic materials: Nonmetal excellent corrosion resistance, as long as the use temperature and pressure of the valve meets the requirements of non-metallic materials, corrosion can not only solve problems, but also saves precious metals.

2. According to media a corrosion-resistant material: in practice, medium corrosion is very complex, even with a valve used in media materials, media different from the density, temperature, pressure, medium on material corrosion are not the same, medium temperature every 10 c, corrosion rate increase of about 1-3 times.

3. spray coating: coating is the most widely used antiseptic means on valve products are an indispensable preservative materials and marking.

4. surface treatment of metals: than sleep on metal surface treatment coating, surface infiltration and surface oxide passivation, with the aim of improving corrosion resistance of metals, metal machinery.

5. Add corrosion inhibitors: corrosion and corrosion, in a small number of other special substances, can significantly slow the rate of metal corrosion, this particular substance known as corrosion inhibitor.
