There is no practical difference in scope; "RP" stands for Recommended Practice, and "SP" stands for Standard Practice. The document was rebranded, with the (and later 2018) representing the most recent, updated technical guidance. Conclusion

While primarily aimed at 300-series stainless steel (e.g., 304, 316), the standard also covers other austenitic alloys prone to sensitization.

: This could involve guidelines for designing, installing, and maintaining impressed current cathodic protection (ICCP) systems used to protect pipelines, storage tanks, and other metallic structures from corrosion.

Guidance on determining when mitigation is mandatory versus recommended.

Incorrect chemical concentrations for neutralizing solutions.

Circulate Na₂CO₃ + NaNO₃ solution before breaching containment. Neutralize potential acid formation on contact. There is no practical difference in scope; "RP"

The standard outlines how to prevent cracking that occurs when sulfide scales on metal surfaces react with oxygen and moisture to form polythionic acid.

Years later, when the next revision of SP0170 was circulated for public comment, Maya kept a single printed copy with the yellowed sticky note scanned and clipped inside. She submitted a concise proposed change: language encouraging site-specific overlay checks and recognition of mobile or transient measurement techniques where static coupons and fixed probes might miss early damage. She attached anonymized case studies from Site 7 showing how supplemental actions prevented a major shutdown.

While NACE SP0170 is the primary standard for PTA SCC mitigation during shutdowns, it is not used in isolation. A robust integrity management program integrates it with other relevant standards. : This could involve guidelines for designing, installing,

Typically a 1% to 2% sodium carbonate (soda ash) solution in water.

“You’re telling me a four-page section on mechanical isolation just saved my flare line?”

For refinery professionals and engineers, (now maintained by AMPP ) is a critical standard practice for maintaining the integrity of stainless steel equipment during maintenance periods.
