A: Approximately every 5-7 years. The last major revision was 2020. Always check AMPP.org for reaffirmation or revision status.
The standard explains the electrochemical process behind Polythionic Acid Stress Corrosion Cracking (PASCC). It details the specific alloy types that are susceptible (such as 304SS, 316SS, and Incoloy alloys) and identifies the "danger zone" of temperatures and environments where cracking is most likely to occur during a shutdown.
If you work in the oil and gas, petrochemical, or heavy industrial sectors, you know that corrosion isn't just a maintenance issue—it’s a safety and financial crisis waiting to happen.
Specifically, if you deal with vessels, tanks, or piping that sit idle or operate at temperatures that allow moisture to gather, you are fighting a silent enemy: Under-Deposit Corrosion.
This is where NACE SP0170 becomes the industry bible. If you’ve been searching for the NACE SP0170 PDF to clarify your preservation protocols, this post breaks down exactly what the standard covers, why it matters, and how to use it effectively.
