AMPP - The Association for Materials Protection and Performance Overview of NACE SP0170
Do not rely on a bootleg copy from a forum. Purchase the official PDF from AMPP, read it cover to cover, and integrate its requirements into your material selection and quality assurance workflows. In the sour service arena, the standard is not a suggestion—it is the law of physics, enforced by the potential for catastrophic failure.
While you may be searching specifically for a "NACE SP0170 PDF 2021," the industry's current authoritative document is the . This standard remains a cornerstone of refinery safety, providing critical, lifecycle-saving guidance for protecting equipment during shutdowns and startups from the dangers of polythionic acid stress corrosion cracking. nace sp0170 pdf 2021
The 2018/2021 approach encourages a risk analysis to determine the appropriate method (wash vs. dry air) based on equipment history, metallurgy, and severity of exposure.
The latest version of the standard for protecting equipment during refinery shutdowns is . While some search for a "2021" version, the 2018 edition remains the current active standard practice. AMPP - The Association for Materials Protection and
: Keeping the equipment dry by circulating dry air (dew point below negative 15 raised to the composed with power C 5 raised to the composed with power F ) to stop the corrosion reaction. Exclusion of Air
: Preventing the formation of liquid water by maintaining a dry air environment. While you may be searching specifically for a
The standard emphasizes the importance of safety and environmental protection. Implementing these practices correctly can prevent accidents and reduce environmental impact.
Keeping the equipment dry prevents the reaction needed to form the acid.
