Nace Sp0198 Pdf
NACE SP0198 adopts a systems approach, covering:
The coating must resist corrosion even when submerged in water, which often happens in CUI scenarios (below dew point).
Epoxy Phenolic or Specialized Carbon-Resin coatings to prevent Chloride Stress Corrosion Cracking (CSCC)
By addressing corrosion at the design stage, companies save millions in unplanned maintenance and repairs. nace sp0198 pdf

NACE SP0198 "Control of Corrosion Under Thermal Insulation and Fireproofing Materials—A Systems Approach," is a critical industry standard for mitigating Corrosion Under Insulation (CUI)
Typically requires a minimum of an SSPC-SP 10 / NACE No. 2 (Near-White Metal Blast Cleaning) with a sharp, angular anchor profile (usually 2.0 to 3.5 mils) to ensure mechanical bonding of high-performance epoxies or TSA.
: Focuses on general and localized thinning [2, 4].
The only safe and compliant source is the (formerly NACE International).
The NACE SP0198 standard outlines best practices to prevent water ingress—the primary cause of CUI—and to protect the metal if water does enter the system. 1. Design Considerations
