Composite materials are being widely implemented for repair scenarios within refineries – domestically and around the world. This paper will discuss concerns, considerations, and needs typically encountered when using Engineered Composite Repair systems to repair live, operating piping systems in a plant environment.
Material requirements for resistance to sulfide stress cracking (SSC) in sour refinery process environments (i.e., environments that contain wet hydrogen sulfide [H2S]). AKA "wet H2S cracking".
CORRECTION OF PUBLICATION:
In January 2016, NACE published an incorrect version of ANSI/NACE MR0103/ISO 17945:2015 (Petroleum, petrochemical and natural gas industries — Metallic materials resistant to sulfide stress cracking in corrosive petroleum refining environments). That document was incorrectly titled ANSI/NACE MR0103/ISO 17495:2016. The erroneous standard was retracted at the time and the NACE Store has the corrected version. NOTE: The contents of both versions of the standard are identical. The only discrepancies are in the title.
NOTE: We are in the process of back adopting the ISO 15156:2020 edition to become the ANSI/NACE MR0175 standard. We will advise when the new version is available for purchase.

Selection and qualification of carbon and low-alloy steels, corrosion-resistant alloys, and other alloys for service in equipment in oil and natural gas production and NG treatment plants in H2S-containing
DOWNLOADABLE HISTORICAL DOCUMENT. This NACE standard (material requirements) is one step in a series of committee studies, reports, symposia, and standards that have been sponsored by Group Committee T-1 (Corrosion Control in Petroleum Production) relating to the general problem of sulfide stress cracking (SSC) of metals. Much of this work has been directed toward the oil and gas production industry. Many of the guidelines and specific requirements in this standard are based on field experience with the materials listed, as used in specific components, and may be applicable to other components and equipment in the oil production industry or to other industries. Users of this standard must be cautious in extrapolating the content of this standard for use beyond its scope.
