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). The recommended practices in this standard are 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.
It will cover 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 will also cover all the more modern methods of nondestructive examination (NDE) for inspection for CUI without having to remove the insulation.

Three new recommended practices (RP) are under way within the API Inspection Subcommittee (SCI) which will add to the list of SCI standards available to owner-users to improve their mechanical integrity (MI) and inspection programs. |
Although CUI is widely recognized as a primary driver for damage in the petrochemical industry, the solutions often lack the sophistication devoted to other damage mechanisms.
