Concentrated sulfuric acid presents a unique paradox. While it is highly corrosive in general, at high concentrations (>90%) and ambient temperatures, it can actually form a protective iron sulfate film on certain materials, allowing them to be used safely. NACE RP0391 was created to define exactly which materials exploit this phenomenon and which fail catastrophically.

(now updated to NACE SP0391 ) is the essential industry roadmap for handling one of the world's most corrosive chemicals: concentrated sulfuric acid. If you are looking for the NACE SP0391 Standard , it provides the critical engineering guidelines needed to prevent catastrophic tank failures and environmental leaks in chemical processing.

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.

Yes, provided the resin is hydrocarbon-resistant. The standard covers FRP for hydrocarbon service, but check for specific fuel-grade additives.
