标准范围
This part of ISO 15156 gives requirements and recommendations for the selection and qualificationof carbon and low-alloy steels for service in equipment used in oil and natural gas production andnatural gas treatment plants in H2S-containing environments, whose failure can pose a risk to thehealth and safety of the public and personnel or to the environment. It can be applied to help to avoidcostly corrosion damage to the equipment itself. It supplements, but does not replace, the materialsrequirements of the appropriate design codes, standards or regulations.This part of ISO 15156 addresses the resistance of these steels to damage that can be caused by sulfidestress-cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking(SOHIC) and soft-zone cracking (SZC).This part of ISO 15156 also addresses the resistance of these steels to hydrogen-induced cracking (HIC)and its possible development into stepwise cracking (SWC).This part of ISO 15156 is concerned only with cracking. Loss of material by general (mass loss) orlocalized corrosion is not addressed.
