Difference between NACE MR0175 and MR0103 Nov 18, 2019 · NACE MR0175 / ISO 15156 applies to harsh upstream exploration and production operations. The NACE MR0103 is specific for downstream refinery environments. In this environment, the process of refining has already removed most of the H2S. Both MR0175 and MR0103 provide specific requirements for different metallic materials.

Materials & Welding:In NACE MR0103, is carbon steel Jun 27, 2018 · ANSI / NACE MR0175 / ISO 15156-2 in paragraph A.2.1.3 provides an allowance, and there is documented evidence that hot formed ASTM A105 and A234 WPB and WPC flanges and fittings are fit for purpose.
Beyond that, MR0175 doesnt apply. For the years between 1975 and 2003, many engineers extrapolated the MR0175 concepts and applied them to the refinery situation (along with the help of RP0472, which even preceded MR0175 and addresses welding concerns and H2S cracking in refineries). The first issue of MR0103 in 2003 filled the gap.
NACE MR0103 and NACE MR0175 - Valve engineering - Jun 05, 2008 · In the Year 2003, 2 more standards released. ie MR0175-2003 & ISO 15156 MR0175/ISO15156 Applicable to both Sulfide Stress Cracking & Chloride Stress Cracking in Oil & Gas Production facilities. Now a Separate standard called NACE MR0103
NACE_MR103.pdf - Reactions Page 1 of 9 November 2004 For example, MR0103 utilizes the alloy grouping philosophy that is used in what is now NACE MR0175/ISO 15156, but did not implement environmental limits such as H 2 S partial pressures, temperature limits, pH restrictions, etc. Materials and material condition requirements are based on a mix of MR0175 requirements and refinery-specific experience.
Translate this pageWhen NACE MR0175 was modified and co-issued as ISO 15156 no 2003, the restrictions on hardness changed from being listed by individual alloys to groups of alloys. Stainless steels and several of the higher alloys supplied by Rolled Alloys are suitable for use in hydrogen sulfide environments and may be ordered to satisfy these requirements .

Understanding Requirements Materials Selection Guide The NACE MR0175/ISO 15156 standard lists prequalified materials for use in upstream oilfield equipment where sulfide-induced stress corrosion cracking may be a risk in sour environments, i.e., in oil/gas/seawater mixtures where hydrogen sulfide (H 2 S) is present.
NACE MR0175 requires alloy 625 to be in the annealed condition. Some suppliers offer alloy 625 quenched off the hammer. This question was raised to the maintenance panel.
