Three strategies for combating the corrosion of steel pipes carrying desalinated potable water Original Research Article

The corrosion of metal pipes carrying potable water is a universal problem. The rate of metal attack depends on a number of factors, the most important of which is the nature of water. Desalinated water is known to be very aggressive. Its aggressivity exceeds that measured in naturally occurring river-, spring- or lake waters. For these reasons, other means must be thought of to improve the performance of pipelines carrying desalinated water. The present paper directs attention to three practical strategies that could be used for this purpose. All work on the waterside of the piping system. The theoretical background of the three strategies is described in short and is referred to in terms of indices: the Hardness Index, Oxygen Index and Corrosion Index. The advantages and drawbacks of each strategy are mentioned.
