ISO 13623:2017规定了石油和天然气行业用于运输的管道系统的设计、材料、施工、测试、操作、维护和废弃的要求，并给出了建议。 它适用于陆地和海上的管道系统、连接井、生产装置、工艺装置、炼油厂和储存设施，包括为连接而在此类设施边界内建造的管道的任何部分。ISO 13623:2017涵盖的管道系统范围如图1所示。 ISO 13623:2017适用于刚性金属管道。 它不适用于柔性管道或由其他材料（如玻璃钢）制成的管道。 ISO 13623:2017适用于所有新管道系统，也适用于对现有管道系统进行的修改。其目的并非追溯适用于现有管道系统。 它描述了管道系统的功能要求，并为管道系统的安全设计、施工、测试、运行、维护和废弃提供了依据。

ISO 13623:2017 specifies requirements and gives recommendations for the design, materials, construction, testing, operation, maintenance and abandonment of pipeline systems used for transportation in the petroleum and natural gas industries. It applies to pipeline systems on-land and offshore, connecting wells, production plants, process plants, refineries and storage facilities, including any section of a pipeline constructed within the boundaries of such facilities for the purpose of its connection. The extent of pipeline systems covered by ISO 13623:2017 is illustrated in Figure 1. ISO 13623:2017 applies to rigid, metallic pipelines. It is not applicable for flexible pipelines or those constructed from other materials, such as glass-reinforced plastics. ISO 13623:2017 is applicable to all new pipeline systems and can be applied to modifications made to existing ones. It is not intended that it applies retroactively to existing pipeline systems. It describes the functional requirements of pipeline systems and provides a basis for their safe design, construction, testing, operation, maintenance and abandonment.
