  • Boiler Water - an overview | ScienceDirect Topics

    Maintaining the pH of boiler water in the range of 9–11 decreases the rate of corrosion; 9.2 to 9.8 is ideal. In low-pressure steam or hot water heating systems, nitrite or chromate provides a protective film on metal surfaces. Filming amines provide a physical barrier to protect metal from corrosion. They are effective in the pH range of 5.5–8.5.
