This feature helps corrosion engineers, inspection personnel, and asset integrity managers quickly understand updates in the (“Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments”). It explains what changed, why it matters, and how to access the official PDF.
Look for NACE SP0472-2020 or the most recent updates on the AMPP Standards Store.
Utilizing steels with low sulfur and low phosphorus levels to reduce HIC susceptibility. Users looking for the "new" PDF should note
NACE RP0472, also known as "Recommended Practice for Inspecting Pipelines," is a standard published by the National Association of Corrosion Engineers (NACE International). The document provides guidelines for inspecting pipelines to ensure their integrity and reliability.
Guidance is provided on using portable hardness testers and converting values (e.g., Rockwell C to Brinell) accurately. 4. Transition to AMPP
The most current version of this standard is NACE SP0472-2020 (Active: Reaffirmed) Consequently, the document is now designated as ANSI/AMPP
AMPP - The Association for Materials Protection and Performance Standard Progression
The standard divides corrosive petroleum refinery process environments into two distinct damage classifications, dictating different prevention methods.
