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

(OP)
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.

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

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.
