NACE MR0175 does it work for you?

Microalloyed Steels for Sour Service International Seminar

NACE MR0175/ISO15156 is the most used and recognised standard for material selection in sour oil and gas production. First published by NACE in 1975 as a sulphide stresscracking document, it has evolved into the more comprehensive ISO 15156 which now covers all forms of cracking that can be generated by wet hydrogen sulphide. This paper explores the standard and the current challenges for the MaintenancePanel and the Oversight Committee (STG299). There are a number of misconceptions which will be explained, in addition vital interpretations which affect the use of the standard will be highlighted. Finally, the relevance of particular test methods cited in the Standard will be explored. (AU) © CBMM
