NACE specified on MTR
NACE specified on MTR
(OP)
MTR for valve shows that materials conform to NACE MR0103. The order was for NACE MR0175 (latest revision). On questioning the supplier, a certificate of conformance was produced which said "All valves designated as NACE conform to NACE MR 0175 and ISO 15156-2 Region 3". I was just wondering if this is normally acceptable? The MTR says MR0103, but a seperate certificate of compliance says MR0175.





RE: NACE specified on MTR
If the valve has anything other than carbon steel of the correct hardness in it, no. In addition, for MR0175, since it is the end user's responsibility to ensure that the materials are correct for the service conditions, the only entity that can certify compliance is the end user.
