While offshore has severe CUI issues, the standard applies to refineries, chemical plants, LNG terminals, pulp and paper mills, and even district heating systems.

Outlines methodologies for identifying CUI, such as Guided Wave Ultrasonic Testing (GWUT), Pulsed Eddy Current (PEC), real-time radiography, and visual inspection via insulation removal. Why You Need the Official PDF Guide

AMPP offers free access to some standards for members through the AMPP Standards Portal, but SP0198 typically requires purchase. However, if you work for a large EPC or owner-operator, check your company’s internal document control system—many firms purchase site licenses. nace sp0198 pdf

Materials treated to repel water (like certain aerogels or treated perlite) are highly favored.

NACE SP0198 establishes a "systems approach" to mitigate CUI, which is one of the most significant and costly threats to the integrity of piping and equipment in the oil, gas, and chemical industries. The standard provides technical guidance on mechanical design, protective coatings, and insulation materials to prevent moisture ingress and manage corrosion on both carbon and stainless steels.

NACE SP0198 addresses this by shifting the focus from to proactive prevention . The standard recognizes that while insulation keeps processes thermally efficient, the underlying protective coating is the primary line of defense against corrosion. Key Protective Coating Systems in NACE SP0198 Identifying the

: Recommendations include epoxy phenolics and thermal spray aluminum (TSA).

: Ensure personnel involved in the design, installation, and maintenance of CP systems are adequately trained and updated on the latest practices.

The standard does not mandate a specific coating but requires that any coating beneath insulation must: Why You Need the Official PDF Guide AMPP

, titled "Control of Corrosion Under Thermal Insulation and Fireproofing Materials—A Systems Approach," is the industry-standard guidance for managing this risk.

If you work internationally, you may need both NACE SP0198 PDF and ISO 19277.
