Surface analysis and electrochemical techniques have been used to characterize the influence of corrosion inhibitors on pit morphology and repassivation. This information has been used to develop a new inhibitor capable of significantly reducing hot surface pitting attack. Data from a major western refinery will be presented as a case history.
