Nace Sp0170 Pdf !new!

The NACE SP0170 standard establishes mandatory practices and recommended procedures to protect both sensitized austenitic stainless steels and other austenitic alloys (such as Alloy 800 or Alloy 825) from PTA-SCC.

From a review of recent technical literature, industry focus is shifting beyond the standard's existing mitigation methods. Research is being conducted on developing stabilized austenitic stainless steels with extra-low carbon content to provide inherent resistance to sensitization and PTA SCC, potentially reducing or eliminating the need for some of the shutdown procedures outlined in NACE SP0170 . However, until such materials become universally adopted, NACE SP0170-2018 remains the cornerstone of safe refinery shutdown operations. nace sp0170 pdf

Furthermore, other NACE standards provide essential corrosion control guidance. For example, NACE SP0169 is the foundational standard for controlling external corrosion on underground or submerged metallic piping, typically using cathodic protection . The control of external corrosion is an entirely different discipline, but both standards contribute to a facility's overall asset integrity. The NACE SP0170 standard establishes mandatory practices and
