How to prevent corrosion of the metal valve hand wheel? The pump valve, the fire valve, the hand wheel of the oil pump valve, and the valve body of the gas itself are all metal materials, and they will be damaged in chemical and telephone structures, but more reasons. The phenomenon is also the corrosion of the metal material itself and the surrounding environment.
When the valve hand wheel will be eroded under what circumstances? The first is to prevent its chemical corrosion but to prevent its electrochemical corrosion, this should consider its own pressure, temperature and so on. Knowing the performance parameters of corrosion can help merchants to store their products: If the corrosion rate of the product is less than 0.001 mm/year, it can be said that it is completely corrosion resistant. If two speeds between 0.001 and 1.0 mm/year are considered corrosion resistant, it is dangerous if the corrosion level exceeds 1.0 or even 10 mm/year.
The problem of corrosion protection is very complicated but the valve handwheel itself has not encountered problems or bottlenecks, because the technical processing of this piece has been professionally dealt with according to the parameters, and it is also industrially reasonable long-term practical experience in materials. Generally, steel materials are generally protected by paint and the appearance is also more beautiful.
