MANAGING THE INTEGRITY OF INSULATED EQUIPMENT: SELECTING THE RIGHT NDE TECHNIQUE

摘要

Corrosion under Insulation (CUI) has been occurring since we started insulating equipment. However, most of the CUI reported until the '70s developed in stainless-steel due to stress corrosion cracking. At that time, with limited insulation, carbon steel equipment did not develop significant CUI. Since then, carbon steel piping, tanks and vessels have been more frequently insulated to save energy costs and add personal protection, leading to more opportunities for CUI to develop.
