EN ISO 15156-1:2015 Petroleum and natural gas industries - Materials for use in H2S-containing environments in oil and gas production - Part 1: General principles for selection of cracking-resistant materials (ISO 15156-1:2015)
This part of ISO 15156 describes the general principles, identifies requirements and provides recommendations for the selection and qualification of metallic materials for use in oil and gas production facilities and in sour gas processing facilities in H2S-containing environments, the failure of which poses a possible health and safety hazard May pose a safety risk to the general public and personnel or to the environment. It can be used to avoid costly damage due to corrosion of the system itself. It supplements, but does not replace, the requirements for materials contained in relevant design guidelines, standards or regulations. This part of ISO 15156 covers all types of cracking that can be caused by H2S, including H2S-induced stress corrosion cracking (SSC), stress corrosion cracking (SCC), hydrogen-induced cracking (HIC) and step cracking (SWC), stress-oriented hydrogen-induced cracking (SOHIC), soft zone cracking ( SZC) and galvanically induced hydrogen cracking (GHSC). Table 1 provides a non-exhaustive list of equipment falling within the scope of this part of ISO 15156, including approved exceptions. This part of ISO 15156 applies to the qualification and selection of materials for equipment designed and constructed using load-driven design methods. See Section 5 for designs using strain-based design methods. This part of ISO 15156 is not necessarily appropriate for application to equipment in refineries or processes and facilities downstream of oil and gas production.
