There are certain reasons for bolt rust.
The following are some of the reasons for valve bolt rust.
The corrosion products produced by different materials have different acidity and alkalinity. Under normal circumstances, through the PH test, if the higher the measured pH, the higher the OH- in the etching solution, the more stable the protective film will be formed, and the charge transfer resistance will be increased, thereby improving the resistance and corrosive. The acidic environment is an important cause of corrosion of valve bolts in nuclear power plants. In addition, due to the presence of certain gaps in the bolt joints, these gap locations are more susceptible to corrosion by acidic environments.
