How to prevent corrosion of stainless steel handwheel of valve? Pump valve, fire valve, hand wheel for oil pump valve and valve body are all metal materials, which will be damaged in the chemical and electrolytic structure. However, the corrosion is caused by the interaction between the metal material itself and the surrounding environment.
Valve stainless steel handwheel under what circumstances will be corroded? The main one is to prevent chemical corrosion but to prevent electrochemical corrosion, which is to take into account the pressure, the temperature and so on. Knowing the corrosion performance parameters is a good way to store the product: if the corrosion rate is less than 0.001mm/year, the product is completely corrosion-resistant. If the speed is between 0.001mm and 1.0mm/year, two of these grades are still considered corrosion resistant, but if the corrosion exceeds 1.0mm/year or even 10mm/year, it is dangerous.
The problem of corrosion prevention is very complex, but the valve handwheel itself did not encounter problems or bottlenecks, because the technical treatment of this part has long been done according to the parameters of the professional treatment, in terms of material is also a long-term industrial reasonable practical experience. Generally steel materials are painted to protect the appearance is more beautiful.
