European field monitoring programs and subsequent laboratory investigations have shown that excessive cathodic protection (CP), combined with induced AC, enhances the risk of corrosion. Increasing the ...

Alternating current (AC) corrosion represents a significant challenge for pipeline integrity, particularly where high-voltage power lines and electrified railways coexist with buried pipelines. The ...

This practice permits measurement of AC current density and evaluation of corrosion products and pits. Recently different criteria to assess AC corrosion risk have been proposed that are based on the ...

In the last six years or so there has been a flurry of reports of AC corrosion on buried pipelines. Statistics are difficult to acquire, mainly because the link between AC and corrosion has not always ...
