Oxidation reduction potential (ORP) measurement can be an effective means for maintaining the state of feedwater for power station to be oxidizing, neutral, or reducing. In order to investigate the characteristics of ORP and its correlation with metal corrosion in high temperature water, a series of experiments including electrochemical measurement and simulated corrosion experiment were carried out. The results show that the ORP increases with the increase of dissolved oxygen content, while decreases with the increase of pH and temperature. Be...
