[ Corrosion Control ]

Those keeping track of our journey through the pipeline competencies might remember a couple of weeks ago, a competency was described for the principles of corrosion.  That competency is about the mechanisms of corrosion itself, while this one is about controlling (stopping) that corrosion. 

While it’s not expressly stated in the competency description, my understanding is there are really only two effective methods of corrosion control: good coatings, and cathodic protection.  Although along with knowledge of those aspects (for which there is plenty to know), a pipeline engineer should also know about interference testing requirements, earthing, stray currents and shielding.
