OVERVIEW: Chemcote was engaged to provide long term protection to assets in a highly aggressive environment. Salt water mains supplying a condenser were externally corroded, and the requirement was for urgent repairs with minimal disruption to plant operation. A 20 year life extension is expected using Chemcote’s solution.
