标准摘要
[中文适用范围]： 本文件介绍了根据 ISO 13623 定义的管道系统使用寿命延长至其规定设计寿命的评估要求和相关指南。本文件适用于陆上和海上刚性金属管道和立管[包括钢悬链立管 (SCR)]。本文件不直接适用于以下情况：— 柔性管道；— 由其他材料（例如玻璃钢或聚合物）制成的管道；— 脐带缆（用于控制或化学输送服务，或两者兼有）；— 上部设备和管道（超出根据当地监管要求定义的管道系统限制范围）；— 管道保护和支撑结构及组件。但是，用户可自行决定将本文定义的评估流程应用于上述内容的寿命延长评估。本文件讨论的是寿命延长，即对原始设计前提的更改。它也适用于对设计前提的其他更改，例如最大允许工作压力 (MAOP) 重新评级或对输送流体的更改，具体取决于用户。 [外文原描述]： This document presents assessment requirements and associated guidance for extending the service life of a pipeline system, as defined in ISO 13623, beyond its specified design life. It applies to both onshore and offshore rigid metallic pipelines and risers [including steel catenary risers (SCRs)]. This document is not directly applicable to the following: — flexible pipelines; — pipelines constructed from other materials, such as glass reinforced plastics or polymers; — umbilicals (control or chemical conveyance service, or both); — topsides equipment and piping (outside of pipeline system limits defined in accordance with local regulatory requirements); — pipeline protection and support structures and components. However, the assessment process defined herein can be applied in the lifetime extension assessment of the above at the discretion of the user. This document addresses life extension, which is a change to the original design premise. It is also applicable to other changes to the design premise, such as maximum allowable operating pressure (MAOP) re-ratings or a change to the conveyed fluids, at the discretion of the user.
