标准范围
本文件给出了CRAs（耐腐蚀合金）和其他合金的选择和鉴定要求和建议，这些合金用于含H2S环境中的石油和天然气生产以及天然气处理厂的设备，其故障可能对公众和人员或环境的健康和安全构成风险。它可以用来帮助避免对设备本身造成代价高昂的腐蚀损坏。它补充但不取代适当的设计规范、标准或法规的材料要求。本文件阐述了这些材料对硫化物应力开裂（SSC）、应力腐蚀开裂（SCC）和电致氢应力开裂（GHSC）可能引起的损坏的抵抗力。这份文件只涉及破解。未解决一般（质量损失）或局部腐蚀造成的材料损失。表1提供了本文件适用的设备的非详尽列表，包括排除设备。本文件适用于使用负荷控制设计方法设计和建造的设备的材料鉴定和选择。关于利用基于应变的设计方法进行设计，见ISO 15156？1:20 20，第5条。本文件不一定适用于精炼或下游工艺和设备中使用的设备。
This document 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 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.This document addresses the resistance of these materials to damage that can be caused by sulfide stress cracking (SSC), stress corrosion cracking (SCC), and galvanically induced hydrogen stress cracking (GHSC).This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed.Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions.This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see ISO 15156？1:2020, Clause 5.This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.
