NACE TM-0177 testing of CRA
NACE TM-0177 testing of CRA
(OP)
Hi all,
As per API 5CRA, Casing and Tubing's are classified into following groups:
Group 1: Super 13 Martensitic
Group 2: 22% Cr or 25% duplex or super duplex
Group 3: 28% Cr Austenitic
Group 4: Alloy 825 Nickel base alloys
My client is asking for NACE TM-0177 Method A testing for above material grades.
As per my understanding, NACE TM-0177 test is not applicable for CRA's(Corrosion Resistant Alloys).
Please advise.
Thanks





RE: NACE TM-0177 testing of CRA
yes it is, testing as per NACE TM0177 can be applied to SS material as per annex B of NACE MR0175 part 3 because stainless steels can also be susceptible to damage by wet H2S cracking
RE: NACE TM-0177 testing of CRA
It depends on what the alloy is sensitive to and what the severity of the conditions are.
