When moisture does reach the metal surface—which is almost inevitable over a long service life—a high-performance coating system serves as the primary defense. NACE SP0198 categorizes coatings based on their service temperature. For example, are widely recognized in the industry as a reliable choice for protection across the critical CUI temperature range, which is identified in the standard as roughly -4°C to 175°C (-25°F to 350°F) for carbon steel. For equipment with skin temperatures above 175°C (350°F), corrosion rates are generally lower as the surface remains dry, though CUI can still occur in localized, cooler areas.

Insulation materials are inherently porous or contain joints that can trap moisture. When water (from rain, deluge systems, washdowns, or condensation) penetrates the outer weather barrier or cladding, it becomes trapped against the hot or cycling metal surface. This environment accelerates corrosion due to: nace sp0198 pdf

Prevention is ideal, but detection is mandatory. NACE SP0198 provides insight into inspection methodologies, including visual inspection, profile radiography, and pulsed eddy current (PEC), allowing operators to find CUI without the costly process of stripping away the insulation entirely.
