We were asked to perform a failure analysis to determine the cause of the corrosion of irrigation piping – that may be related to issues with self-draining gaskets and/or non-conformance to specification. The investigation involved:
Chloride pitting was discovered – which is common as the chloride ion is known to facilitate breakdown of the aluminum oxide film.
In order to eliminate this mechanisms promoting accelerated corrosion attack, we recommended the reduction of chlorine/chloride in the irrigation fluid system.
