Abstract
This review is largely concerned with work carried out on the long-term behaviour of aluminium in fresh waters and the methods developed for predicting service behaviour. The corrosion behaviour of aluminium in waters is discussed and it is shown that aluminium corrodes by pitting. The effect of pitting on tensile properties, on the bursting strength of pipes, and on the hydraulic efficiency of pipes is described. It is shown that the most important consideration is that of preventing of perforation by pitting. The mechanism of pit initiation and pit growth and its practical Implications are described. The methods used by these Laboratories for determining the corrosivities of waters are given. The alloys in general use.in fresh waters are given together with their chemical compositions. The types of all aplicationS are briefly mentioned, and a specific application, that of water pipelines, is then dealt With in detail. Finally, the methods usedfor preventing perforation are summarised.
