NACE RP0391 is a standard practice developed by the National Association of Corrosion Engineers (NACE) that provides guidelines for the protection of steel pipelines and other metallic structures from corrosion using cathodic protection (CP) systems.
In the industrial world, handling sulfuric acid (often called the "King of Acids") is a high-stakes balancing act. To keep systems safe and durable, engineers rely on a specific rulebook: the NACE Standard RP0391 , officially titled nace rp 0391 pdf
ANSI Webstore: Offers NACE RP0391-2001 for those needing historical compliance data. NACE RP0391 is a standard practice developed by
Provides guidance on using carbon steel, stainless steels, and various alloys. Corrosion Phenomena: Addresses specific risks like hydrogen grooving Visual inspection for blisters, cracks, or exposed fibers
NACE RP 0391 is a Recommended Practice published by NACE International (now AMPP) that gives guidance on evaluating, selecting, applying, and testing coatings for the internal protection of metallic pipelines and piping systems handling various fluids. It focuses on corrosion control inside pipelines (e.g., water, oil, gas, produced water) where internal coatings, linings, and auxiliary measures (pigging, corrosion inhibitors) are used to extend service life and reduce maintenance.
