Base Material Selection: It provides guidelines on selecting carbon steels with lower carbon equivalents to reduce hardenability. nace rp0472 pdf

  • MR0175: For upstream (wellhead to manifold). Sour service (H₂S partial pressure > 0.05 psi).
  • RP0472: For downstream (refinery). Refining environments (often higher temperatures and chlorides).
  • Result: Using the wrong standard fails the audit.
