Overview of API RP 583 - Corrosion Under Insulation and Fireproofing

API RP 583, Corrosion Under Insulation and Fireproofing, covers the design, maintenance, inspection and mitigation practices for pressure equipment, piping, and storage tanks due to external Corrosion Under Insulation (CUI) and Corrosion Under Fireproofing (CUF). This recommended practice is intended to provide the user with information that will improve plant reliability by describing all the variables that give rise to CUI including: temperature, coating type and age, insulation types, climate effects, insulation maintenance practices, etc. and provide a method of risk ranking equipment for CUI potential based on the primary factors that affect the potential for CUI.

API RP 583 covers External Chloride Stress Corrosion Cracking (ECSCC) of stainless steels under insulation, as well as general and localized metal loss of carbon and low alloy steels. It also covers all the more modern methods of nondestructive examination (NDE) for inspection for CUI without having to remove the insulation.
