NACE MR0175 requirement for ASTM B61/62(Bronze Alloy)

[khanvessel]

We need to purchase bronze valve for slops system, fluid is sour. Is it required for bronze valvs manufactured from ASTM B61/62 per MSS SP-72 to be NACE MR0175 compliant?

Thanks in advance for help.

Copper alloys will be 'NACE compliant' without any manufacturing restrictions by virtue of subclause A.12.1 of Part 3. In addition, if the system operates below 4.5 bar a then 'NACE' may be waived.
