3.3.- CORROSION RESISTANCE OF COPPER AND STAINLESS STEEL OF PLATES EXCHANGER
(WATER EXCHANGER)
GUIDE TO MEASURE A ANALYSIS OF THE WATER IN THE CIRCUIT.
The resistance guide below is an attempt of give a picture of the corrosion resistance of the stainless steel of the type AISI
316 and pure copper in the water, to a number of important chemical factors. The actual corrosion is however a very complex
process inuenced by many factors in combination. This table is therefore a considerable simplication and should not be
overvalued.
Explanations:
+ Good resistance under normal conditions
0 Corrosion problems can occur especially when the factors are valued as 0
- Use is not recommended
