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
The standard provides extensive information on the corrosion resistance of various materials in concentrated sulfuric acid, covering a wide range of commercially available alloys suitable for acid service.
: When purchasing the standard from official vendors (such as ANSI, Techstreet, Accuristech, or the NACE Store), always search for NACE SP0391-2016 to ensure you are obtaining the most current, active version.
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. nace rp 0391 pdf

or lower concentrations, the standard implies the need for higher alloys or lining materials, though the main focus is on carbon steel optimization. Acquiring the NACE RP0391 PDF
Used for subsea manifolds and tubing due to high pitting resistance. Originally established in 1991 and revised in 2001
Verifying that existing infrastructure meets industry-recognized benchmarks.
Users seeking the official document can find it through authorized standards organizations:
The document is a technical guide for engineers and maintenance personnel. It provides specific recommendations for selecting materials, primarily , for systems that handle commercial concentrated (90% to 100%) sulfuric acid at ambient temperatures (up to 50°C or 120°F). It details the performance and limitations of various
You can find the document listed as NACE Standard RP0391-2001 on the ANSI Webstore.
The standard practice was originally developed in 1991 by the National Association of Corrosion Engineers (NACE, now operating under AMPP) to standardize handling practices across chemical plants. Key Scope Parameters : 90% to 100% by weight.
The oil and gas industry is a complex and demanding sector, where corrosion can have devastating consequences on equipment, infrastructure, and the environment. Corrosion inhibitors play a crucial role in preventing and mitigating corrosion in oil and gas operations. To ensure the effective use of these inhibitors, the NACE International (National Association of Corrosion Engineers) has developed a standard, RP 0391, which provides guidelines for evaluating corrosion inhibitors for use in oil and gas operations.
The correct standard for wet H₂S environments in refineries is . This standard covers:
The standard provides selection and testing criteria for several high-performance material classes:
