Cellular glass is frequently specified because it does not absorb liquid water, preventing moisture from trapping against the pipe. 3. Mechanical Design Practices
TSA provides both a physical barrier and galvanic (sacrificial) protection to the underlying steel substrate. It is highly favored for long-term protection (often exceeding 25–30 years) in harsh offshore or highly cyclic high-temperature environments. 5. Surface Preparation and Application Standards
Use the standard’s (Risk Assessment Matrix) – reproduced in many training guides – to categorize assets as Low, Moderate, or High Risk. nace sp0198 pdf
Specify high-performance coatings like Epoxy Novolacs or TSA. Coating Material Specs
Used effectively up to 300°F (149°C) to form a barrier against chloride-laden moisture. Cellular glass is frequently specified because it does
NACE (AMPP) offers a specifically based on SP0198. Use the PDF as a training manual.
Not all insulations are equal for CUI control. SP0198 advises: It is highly favored for long-term protection (often
: The standard outlines strategies for identifying CUI, which often involves non-destructive testing (NDT) or visual inspection by removing insulation in high-risk areas [1, 2]. Why It Matters
Choosing insulation materials that minimize corrosion risks.
