An evaluation of corrosion protection properties of vapor corrosion inhibitors for fire water systems protection was performed. Two common environments are found in such applications:
1. Dry systems
2. Wet systems with water
Three-phase protection ability of VpCI allows them to be effective in the conditions present in such systems. Corrosion tests were carried out depicting the above conditions in the laboratory. This paper provides lab data obtained from such testing and an actual field usage with a discussion on the results.
