What are the NACE MR0175 requirements for ASTM A216 Grade WCB valves?
ASTM A216 WCB valves are widely used in hydrocarbon processing. NACE MR0175 is applicable when materials like ASTM A216 WCB are exposed to H2S. The sour service requirements for ASTM A216 WCB are included in NACE MR0175..
ASME IX P1 material is listed as acceptable in NACE MR0175, but this does not mean that the general requirements do not apply, i.e. hardness heat treatment, HIC resistance etc. At Oil & Gas Corrosion we can help you confirm material compliance to ANSI/NACE MR0175/ISO 15156.
