Internal corrosion of steel piping in water mains

Abstract

Recently acquired quantitative data on the initial corrosion rate of steel vs. the Ryznar index of natural waters are given as a basis of provision of overall service life of steel piping. In the light of the available fundamental knowledge of aqueous corrosion, the mechanism of high‐rate localised attack of coated steel piping from carbonated waters is outlined. A representative case history of multiple perforation of bitumen‐coated steel piping from localised corrosion is reported for a municipal potable water distribution system. Practical protective measures and corrosion monitoring techniques are considered in relation to the most aggressive waters.
