Physical design dictates whether water sheds off a system or enters it. NACE SP0198 highlights design best practices, including:
NACE SP0198 is a globally recognized standard practice that provides industrial designers, facility owners, and maintenance engineers with a systematic approach to controlling CUI and CUF. The standard focuses primarily on carbon steels, low-alloy steels, and austenitic and duplex stainless steels commonly used in chemical plants, oil refineries, and offshore platforms.
As of 2021, NACE International merged with SSPC to form (Association for Materials Protection and Performance). Therefore, new versions of SP0198 are now released under the AMPP brand, though the standard number remains "NACE SP0198" for historical reference. nace sp0198 pdf
Facilities located in marine, coastal, or heavily polluted industrial areas introduce aggressive contaminants like chlorides and sulfur compounds. Key Content Covered in the NACE SP0198 Standard
When insulation is necessary, a high-performance coating is required as a secondary line of defense. NACE SP0198 provides guidelines for selecting coatings that can withstand:
CUI is an aggressive and silent phenomenon that occurs when moisture infiltrates an insulation system and comes into contact with the metal surface beneath, often leading to hidden damage. Key triggers include: What is currently specified for the project

It covers carbon steel, austenitic stainless steels, and duplex stainless steels.
Industry professionals frequently need to reference this document directly for project specifications or safety audits. Because NACE (AMPP) holds the copyright for this standard, it is not available for free public distribution. The standard focuses primarily on carbon steels, low-alloy
Typical formulations include epoxy phenolics and novolac epoxies.
NACE SP0198 Current Revision: Typically SP0198-2016 (or latest revision by AMPP) Focus: A "Systems Approach" to preventing and managing Corrosion Under Insulation (CUI) and Corrosion Under Fireproofing (CUF).
