NACE RP0472 is a standard recommended practice originally developed by NACE International (now part of AMPP) to protect carbon steel equipment in corrosive petroleum refining environments. Its full title is "Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments".

If you are designing or repairing carbon steel weldments in wet H₂S service, – NACE RP0472 also requires controlling residual stress, preheat, interpass temperature, and proper filler metals. Always qualify welds with actual hardness testing on production welds or mock-ups. nace rp0472 pdf
