“Corrosion Under Insulation: Differences In Gel Technology” by: Nate Brink

Corrosion under insulation (CUI) of steel operating equipment and piping is a significant issue in the ammonia refrigeration, chilled water, chemical, and petroleum industries. A systems approach to CUI includes the correct material selection and design of the jacketing, insulation, and coating. This approach will help prevent CUI, but many corrosion engineers would agree that electrolytes will eventually find their way into even the best system. Selecting the right coating is extremely important, as the CUI coating is the last line of defense for keeping the electrolyte from the metal surface, which would cause corrosion.  [Read More…]
