NACE RP 0391 (now standardized under AMPP as ) is the definitive industry standard for “Materials for the Handling and Storage of Dry FGD Waste.” But finding a free PDF of this document online is a minefield. Here is what you need to know about the standard, why it matters, and why you should be careful where you download it.
In practice, deepwater engineers use standards in tandem to specify materials that are resistant to internal reservoir fluids (MR0175) and external subsea environments (RP0391). How to Access the NACE RP0391 PDF Legally

It covers commercial concentrated sulfuric acid (90% to 100% concentration) at ambient temperatures , typically defined as up to 50°C (120°F) .
It details the performance and limitations of various materials, such as carbon steel , which forms a protective ferrous sulfate (FeSO4) layer in concentrated acid, though it remains vulnerable to high flow rates or turbulence.

Originally established in 1991 and revised in 2001 and 2016, this document (full title: Materials for the Handling and Storage of Commercial Concentrated Sulfuric Acid ) provides recommended practices for tanks and piping, aiming to prevent corrosion-related failures. Scope and Purpose
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
High nickel and copper content provides resistance across wider velocity and concentration shifts.
The (now updated and designated as NACE SP0391 ) provides comprehensive industry guidelines for the selection of materials, design, and fabrication of systems used to handle and store commercial concentrated sulfuric acid ( H2SO4cap H sub 2 cap S cap O sub 4
