A key phrase in the standard's title is "Systems Approach." NACE SP0198 emphasizes that relying on a single mitigation method is insufficient. Instead, true CUI prevention requires an integrated, multi-faceted strategy that considers the entire insulated system as a whole. This "system" comprises several interdependent components, each of which must be carefully selected and managed.
The insulation itself can be a major contributor to CUI. NACE SP0198 details specific insulation characteristics that have the greatest influence on corrosion:
NACE SP0198 does not exist in a vacuum. It is part of a broader ecosystem of corrosion and coating standards, and it's often used in conjunction with other documents.
Water ingress usually happens due to poor design or mechanical damage to the exterior protective jacketing. The standard provides design recommendations to avoid water traps, including: Designing proper shedding angles on jacketing.
It is crucial to use the latest version to ensure compliance with current industry best practices. Summary of Best Practices (SP0198 Overview) Recommendation nace sp0198 pdf

A coating system is only as good as its surface preparation. NACE SP0198 references joint standards from AMPP, SSPC, and ISO to ensure coatings adhere correctly under insulation.
The Comprehensive Guide to NACE SP0198: Standard Practice for Control of Corrosion Under Insulation
The only safe and compliant source is the (formerly NACE International). A key phrase in the standard's title is "Systems Approach
NACE SP0198 establishes a "systems approach" to mitigate CUI, which is one of the most significant and costly threats to the integrity of piping and equipment in the oil, gas, and chemical industries. The standard provides technical guidance on mechanical design, protective coatings, and insulation materials to prevent moisture ingress and manage corrosion on both carbon and stainless steels. Core Technical Sections
Water condensed from the air.
Corrosion of reinforced concrete structures can lead to significant financial losses and safety risks. One effective method of preventing such corrosion is through the application of cathodic protection (CP) systems. NACE SP0198 provides a comprehensive framework for the application of CP systems on reinforced concrete structures.
The standard outlines specific criteria to prevent ECSCC, heavily relying on epoxy novolacs for lower temperatures and specialized IMM coatings for high-temperature ranges. The insulation itself can be a major contributor to CUI
Choosing insulation materials that minimize corrosion risks.
Searching for a is the first step toward better corrosion control. But the search must end with a legal purchase.
It covers carbon steel, austenitic stainless steels, and duplex stainless steels.
The document has evolved through several revisions to incorporate new technologies and industry experience:
