NACE Standard MR0175/ISO 15156-3: 2009 Petroleum and natural gas industries - Materials for use in H2S-containing environments in oil and gas production - Part 3: Cracking-resistant CRAs (corrosionresistant alloys) and other alloys

An American National Standard. Approved December 2, 2010. The International Organization for Standardization (ISO). Second edition, 2009-10-
15. This second edition cancels and replaces the first edition (ANSI/NACE/ISO 15156-3:2003), of which it constitutes a minor revision. 79р. This part of ANSI/NACE MR0175/ISO 15156 gives requirements and recommendations for the selection and qualification of CRAs (corrosion-resistant alloys) and other alloys for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations.
