Complete Guide to NACE SP0198: Control of Corrosion Under Insulation (CUI)
Inert Multiphase Polymeric Matrix (IMPM) or Thermal Spray Aluminum (TSA). 4. Key Materials Highlighted in the Standard Liquid Applied Coatings
NACE SP0198 outlines how different insulation materials behave when moisture enters the system. It offers guidance on selecting insulation types (such as hydrophobic aerogel, cellular glass, calcium silicate, or mineral wool) based on their water-retention properties and chemical neutrality. For example, using insulation with low leachable chlorides is strictly mandated when insulating stainless steel to prevent CISCC. 3. Mechanical Design and Jacketing It covers carbon steel, austenitic stainless steels, and
: Outlines specific coating categories based on temperature ranges and substrate types.
Create a written, risk-based inspection program.
Materials treated to repel water (like certain aerogels or treated perlite) are highly favored. Locating and downloading the official PDF of any
Correct selection of coatings, insulation, and design doubles equipment service life.
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:
As the industry continues to evolve, so too will the standards that govern it. The current active revision is . Since AMPP standards are subject to periodic review, reaffirmation, or revision, a future update could be in development. It is highly recommended to check the official AMPP website for the most current status and any upcoming revisions. The standard's next reaffirmation or revision will ensure it continues to reflect the best available technology and practices for controlling CUI.
Are you primarily concerned with or stainless steel piping? What is the operating temperature range of the equipment?
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.
