标准范围
本文件给出了在含H2S环境中用于石油和天然气生产以及天然气处理厂的设备中使用的碳钢和低合金钢的选择和鉴定的要求和建议，这些设备的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。本文件讨论了这些钢对硫化物应力开裂（SSC）以及应力取向氢致开裂（SOHIC）和软区开裂（SZC）的相关现象引起的损伤的抵抗力。本文件还讨论了这些钢的耐氢性能-诱导开裂（HIC）及其向逐步开裂（SWC）的可能发展。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。对于利用基于应变的设计方法进行设计，参见ISO 15156-1:20 20，第5条。附件A列出了抗SSC的碳钢和低合金钢，A.2.4包括使用铸铁的要求。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 carbon and low-alloy steels 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.This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC).This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC).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.Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast irons.This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.
