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.

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.
This eBook offers practical guidance for, and real examples of, in-service degradation attributed to corrosion under insulation. It provides a detailed discussion on CUI detection, characterization and evaluation, and mitigation or remediation.
This checklist serves as a companion piece to the Inspectioneering webinar, CUI: A Proactive Approach, and contains some elements to consider when looking for data gaps in your CUI program.
Corrosion Under Insulation (CUI) is one of the most well-known damage mechanisms in the O&G and chemical processing industries, yet CUI still makes up a very large percentage of plant maintenance expenditures.
