CSA Z245.1 Steel Linepipe compliance with NACE MR0175/ISO15156-2

CSA Z245.1 Steel Linepipe compliance with NACE MR0175/ISO15156-2

CSA Z245.1 Steel Linepipe compliance with NACE MR0175/ISO15156-2

Hi Everbody,
I came across and noted NACE MR0175/ISO 15156-2 Table A.2 considered API 5L pipes up to grade X65 material as prequalified material for SSC resistance complying with A.2.1 requirements.
May we extend that to CSA Z245.1 Steel Line pipe up to Gr. 448 which has similar Yield strength and same criteria for fabrication as X65 to be prequalified?
Is there any NACE interpretation allowing that?

RE: CSA Z245.1 Steel Linepipe compliance with NACE MR0175/ISO15156-2

Answer to Inquiry #2007-05:

Many steels, including ASTM A 216, are not individually listed in NACE MR0175/ISO 15156-2. As stated in A.2.1.1 General, Para. 3:
"The majority of steels that comply with the general requirements of A.2 are not individually listed; however, for convenience, some examples of such steels are listed in Table A.2, Table A.3 and Table A.4." A.2.1.1 deals only with sulfide stress corrosion resistance.

Essentially, the listing is superfluous and, if it were me, it wouldn't be in the document at all (along with a lot of other things)

If you believe that simply listing the standard and grade alone constitutes "qualification," you might wish to read the standard again. Another common misdirection by the standard, yet it's still there in the 2020 version. This is probably because the standard was written by scientists rather than engineers.
