This tool determines whether the metallic material requirements for resistance to sulfide stress cracking (SCC) for petroleum production, drilling, gathering and flowline equipment, and field processing facilities to be used in hydrogen sulfide (H2S)-bearing hydrocarbon service, as specified in the current NACE MR-0175 Guidelines, need to be applied.

This tool determines sour service requirements. Applicability of the standard is the role of the suitably qualified materials engineer or corrosion engineer.

System Pressure:

H2S Concentration:
