The Complete Guide to NACE RP0472: How to Get the PDF and Why It Matters for Pipeline Integrity

Do Not Confuse RP0472 With Other Standards

• NACE MR0175/ISO 15156 – Material selection for sour service.
• NACE SP0102 – Inspection of linings.
• API RP 582 – Welding guidelines for chemical/petroleum facilities.
• ASME Section IX – Welding qualification (used with RP0472).

1. Scope and purpose

• Defines procedures to evaluate corrosion rates and effectiveness of protective systems for carbon steel exposed to atmospheric environments.
• Provides guidance for test methods, exposure conditions, data collection, and analysis to compare coatings, inhibitors, or design changes.

Report: NACE RP0472 (PDF) — Overview and Key Points

Note: I assume you mean NACE (now AMPP) RP0472 — the Recommended Practice on evaluation of corrosion control methods for atmospheric corrosion of carbon steel structures. Below is a concise, structured report summarizing the document, typical contents, and how to obtain and use the PDF.

4. Typical procedures (summary steps)

1. Select representative carbon steel alloy and specimen geometry.
2. Prepare surface per specified standard (e.g., SP 10, hand/steel brush).
3. Apply protective systems using controlled parameters; record application data.
4. Expose specimens in defined atmospheric categories or run accelerated lab tests.
5. Periodically inspect and measure (visual, thickness, weight-loss, electrochemical impedance).
6. Remove corrosion products per standard method prior to weight-loss measurement.
7. Analyze results, compute corrosion rates (mm/yr or mpy), and compare systems.
8. Prepare final report with raw data, statistical analysis, and recommendations.
