Nace Rp 0391 Pdf
Carbon steel tanks require heavy sacrificial corrosion allowances (typically 3.0 mm to 6.0 mm) added directly to the minimum structural wall thickness.
Static storage tank shells and low-velocity, large-diameter piping. Limitation: Flow velocities must remain extremely low.
For further technical details, researchers often refer to secondary summaries found in ResearchGate reviews or industry handbooks that cite the standard's core requirements. NACE Standard RP0391-2001 - ANSI Webstore
: 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.
The standard is intended to assist engineers as well as Chemical Process Industries (CPI) operations and maintenance personnel who are involved in the design, modification, and maintenance of ambient-temperature concentrated sulfuric acid systems and equipment, with key focus areas including design, storage tanks, and acid handling systems. nace rp 0391 pdf
