5. Conclusion
Controlling corrosion under thermal insulation is an essential factor in the reliability of industrial equipment and the safety of operators.
Compared with other degradation modes, this corrosion has two specific features: its local nature and the difficulty of detecting it early. High-performance, reliable inspection methods are therefore essential. This requires both optimized inspection plans to prioritize the most severe risk zones, possibly using RBI techniques, and proven non-destructive testing methods.
In terms of prevention, today's most effective approaches involve protecting metal surfaces with specific organic and metallic coatings.
