– full title "Standard Practice – Control of Corrosion Under Thermal Insulation and Fireproofing Materials – A Systems Approach" – is a technical standard published by AMPP (formerly NACE International, now merged with SSPC).
If you are implementing a CUI program based on this standard, your checklist should include:
Typically requires a minimum of NACE No. 2/SSPC-SP 10 (Near-White Metal Blast Cleaning) with a sharp, angular anchor profile (usually 38 to 75 micrometers) to ensure mechanical adhesion.
Incorporating newer, high-performance coating technology developed since the 2004 revision. nace sp0198 pdf
Preventing water ingress is just as important as protecting the metal. The standard provides best practices for weather barriers, cladding joints, caulking, and designing equipment to shed water rather than pool it. Classification of Coating Systems in NACE SP0198
By addressing corrosion at the design stage, companies save millions in unplanned maintenance and repairs.
Formulated specifically to be chloride-free to prevent inducing Cl-SCC. – full title "Standard Practice – Control of
NACE SP0198 is a Standard Practice document that provides technical guidance for controlling corrosion under thermal insulation and fireproofing materials. It utilizes a , meaning it does not look at coatings or insulation in isolation. Instead, it examines how coatings, insulation selection, design practices, and environmental conditions interact. Why is this standard critical?
The standard details how to select appropriate insulation materials (e.g., cellular glass, mineral wool, aerogel) and outlines their respective vulnerabilities to water absorption and chloride leaching. It also covers the application of water-resistant fireproofing materials. 4. Weather Barriers and Jacketing
The most heavily utilized sections of the NACE SP0198 PDF are the classification tables for protective coatings. The standard categorizes coatings based on substrate type and operating temperature limits. Carbon Steel Coating Systems (Table 1 Summary) Classification of Coating Systems in NACE SP0198 By
Ensure proper flashing and sealing to prevent water ingress. Conclusion
Frequently specifies epoxy phenolics or novolac epoxies to handle elevated temperatures and chemical exposure.
When downloading or purchasing the document, ensure you are getting the most recent revision to comply with modern industrial safety and environmental regulations. Summary Checklist for Managing CUI via NACE SP0198 Action Item Standard Reference Focus
