标准范围
本文件描述了一般原则，并给出了用于石油和天然气生产设备以及含H2S环境中天然气脱硫厂的金属材料的选择和鉴定的要求和建议，这些设备的故障可能会对公众和人员的健康和安全或环境构成风险。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、标准或法规中给出的材料要求。本文件阐述了H2S可能引起的所有开裂机制，包括硫化物应力开裂、应力腐蚀开裂、氢致开裂和逐步开裂、应力-定向氢致开裂、软区开裂和电致氢应力开裂。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，见第5条。本文件不一定适用于炼油或下游工艺和设备中使用的设备。
This document describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural-gas sweetening plants in H2S-containing environments, where the failure of such equipment 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 given in the appropriate design codes, standards, or regulations.This document addresses all mechanisms of cracking that can be caused by H2S, including sulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking, stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogen stress cracking.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 Clause 5.This document is not necessarily applicable to equipment used in refining or downstream processes and equipment.
