In the industrial sector, few acronym combinations carry as much weight for maintenance engineers and integrity managers as "CUI." Corrosion Under Insulation is a silent, multi-billion-dollar problem that plagues the oil and gas, petrochemical, and energy industries. For professionals seeking the definitive roadmap to tackle this issue, the search term is often the first step toward a solution.
The high search volume for stems from the sheer magnitude of the CUI problem. CUI accounts for a significant percentage of all process industry leaks. It is notoriously difficult to detect because the insulation hides the damage until it is too late. nace sp0198 pdf
One of the most used sections of the standard is , which categorizes protective coatings based on the substrate material and service temperature. In the industrial sector, few acronym combinations carry
NACE SP0198, also known as "Standard Practice for Corrosion Under Insulation and Fireproofing," is a document developed by NACE that provides guidelines for detecting, preventing, and mitigating CUI and corrosion under fireproofing (CUF). The standard practice outlines procedures for inspecting, maintaining, and rehabilitating insulated equipment and piping to prevent corrosion. CUI accounts for a significant percentage of all
By following the guidelines and best practices outlined in this blog post, industries can effectively mitigate the risks associated with CUI and ensure the integrity of their assets.
NACE SP0198, officially titled “The Control of Corrosion Under Thermal Insulation and Fireproofing Materials—A Systems Approach,” is a standard published by AMPP (formerly NACE International and SSPC). It is widely recognized as the primary global standard for managing the hidden threat of corrosion that occurs beneath insulation materials.
Most modern projects require : ISO 20340 for coating qualification (testing), and NACE SP0198 for field execution (inspection).
