You can also prevent CUI through the use of a high-quality insulating material. For example, wrapping an aluminum foil on a pipe before placing the insulating material on it can inhibit corrosion. Aluminum foil acts as a barrier that prevents the insulator from absorbing acidic water. It also ensures it doesn’t reach the outer surface of the pipe.
Preventing Corrosion Under Insulation
