Nace Sp0198 Pdf [better] May 2026

NACE SP0198 (now maintained by AMPP content.ampp.org) is the industry-standard practice for mitigating Corrosion Under Insulation (CUI) and corrosion under fireproofing materials, emphasizing a "systems approach" to protect carbon and stainless steel . The standard provides technical guidance on coatings, material selection, and design to prevent moisture entrapment, with a focus on temperatures between -12°C (10°F) and 175°C (350°F) . For the full standard, visit AMPP content.ampp.org.

1. Design: Ensure piping supports don't act as water sponges.
2. Coating: Apply a high-quality, temperature-resistant coating to all carbon steel in the CUI temperature range.
3. Jacketing: Use stainless steel or aluminum jacketing with proper overlaps (shedding water like roof shingles) and sealed seams.
4. Insulation: Choose low-chloride insulation for stainless steel.
5. Inspection: Establish a schedule to remove insulation at high-risk locations (e.g., low points, nozzle necks, supports) during shutdowns.

Design Considerations: The design of a CP system must consider the specific environment, type of structure, and potential sources of corrosion. nace sp0198 pdf

• Retrofits and repairs of cathodic protection systems.
• Monitoring and testing of CP systems on existing offshore structures.
• Record keeping and data interpretation to verify adequate corrosion control.

1. Materials selection: The guidelines provide recommendations for selecting materials that are resistant to corrosion in environments where hydrocarbons are present.
2. Design and fabrication: The guidelines outline best practices for designing and fabricating equipment to minimize corrosion risks.
3. Installation and maintenance: The guidelines provide recommendations for installing and maintaining equipment to prevent corrosion.
4. Cathodic protection: The guidelines provide guidance on designing and implementing cathodic protection systems to prevent corrosion.

Do not risk your career or your infrastructure on a bootleg scan from 1998. The revisions regarding cathodic protection shielding, weld seam preparation, and soluble salt testing are too critical to ignore. Design: Ensure piping supports don't act as water sponges
