Investigations aimed at evaluating monitoring techniques as a function of the specific water chemistry has been conducted as a part of a Nordic project focused on improving the quality of corrosion monitoring in municipal district heating. A combination of techniques has been selected to measure both general and localised corrosion. Electrochemical techniques (LPR, EIS) as well as direct techniques (high sensitive ER, weight loss, local crevice corrosion current) have been applied. The data show that the water quality in Danish systems is high resulting in low corrosion rates, but changes in the water quality induce localised corrosion. Useful monitoring results have been obtained with high sensitive ER technique (MetriCorr) and crevice corrosion measurements with the LOCORR cell (FORCE TECHNOLOGY).
