The rating is based on the following criteria:
: Provides procedures for applying internal coating systems to railroad tank cars used for acid transport. 5. Accessing the NACE RP 0391 PDF
The feature processes inputs against standard recommendations:
The NACE standard (now redesignated as provides guidelines for the design and selection of materials used in the handling and storage of commercial concentrated sulfuric acid (90 to 100% at ambient temperatures ANSI Webstore Key Technical Details : Specifically covers sulfuric acid concentrations between 90% and 100% by mass at "ambient" temperatures up to 50°C (122°F) nace rp 0391 pdf
Understanding NACE RP0391: The Standard for Materials Performance in Deepwater Production What is NACE RP0391?
When you finally get your hands on the official document, follow this reading strategy:
For storage tank fabrication and internal inspection, use this standard alongside NACE SP0294 (Design, Fabrication, and Inspection of Concentrated Sulfuric Acid Storage Tanks). The rating is based on the following criteria:
If you possess the , treat it as a historical reference or for maintaining legacy equipment. Do not use it for new construction.
A critical warning in the standard involves galvanic corrosion. Mixing copper-based alloys (brass, bronze) with carbon steel in concentrated sulfuric acid can lead to rapid failure. NACE RP0391 provides a compatibility chart for bolting materials and flanges.
NACE RP0391-91 (1991) was updated in 2001. In February 2017, the standard was redesignated as . When you finally get your hands on the

The standard specifies that FRP pipes must consist of:
The document provides guidance on using specialized alloys, such as high-silicon cast iron, or specific types of austenitic stainless steels for components where carbon steel may not be appropriate. 3. Safety and Maintenance
is a standard recommended practice 1.2.4 . It was developed to provide guidance on the selection of materials for tanks, piping, and related equipment. Original Publication: 1991 (NACE Task Group T-5A-18) 1.2.3 . Revision: 2001 (reaffirmed and revised to SP0391) 1.2.4.
at ambient temperatures. It relies on a protective iron sulfate film; however, high velocity or turbulence can strip this film, leading to rapid corrosion.
