The standard identifies three mandatory conditions required for CUI to occur:

The standard is structured to address CUI through multiple layers of protection:

The standard emphasizes that the insulation system (jacketing, caulking, and seals) must be maintained to keep water out in the first place. Why You Need It Compliance:

Asset integrity managers, corrosion engineers, and maintenance professionals frequently search for the to design, specify, and implement reliable protective coating systems. This article provides a comprehensive breakdown of the standard, its core methodologies, and how to apply it to prevent CUI. What is NACE SP0198? nace sp0198 pdf

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.

For carbon steels, the standard divides temperature ranges to address both cryogenic and high-heat applications:

NACE SP0198 is an essential reference for a wide range of industries where insulated equipment is prevalent: What is NACE SP0198

Incorporate Non-Destructive Testing (NDT) methods like Pulsed Eddy Current (PEC), Guided Wave Ultrasonics, or Real-Time Radiography alongside visual inspections of the cladding to catch breaches early. How to Access and Purchase the NACE SP0198 PDF

Cellular glass absorbs zero water, making it a highly effective choice for minimizing CUI risks, though joints must be sealed tightly.

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 For carbon steels, the standard divides temperature ranges

Ideal for immersion-like conditions up to specific temperature thresholds.

Epoxy phenolics, novolac epoxies, and Thermal Spray Aluminum (TSA). Austenitic Stainless Steel (SS):
