管道焊接缺陷合于使用评定技术进展

The Development of Fitness for Service Assessment Standards for Pipeline welding Defects

为保证大型结构及长距离油气输送管线的结构完整性 ,有关国家先后制定了以“合于使用”为原则的缺陷评定标准 ,在管道建设中发挥了巨大作用。重点讨论了 R6、API5 79、BS791 0和 SINTAP评定技术的最新发展与相互联系 ,为我国管道评定技术研究提供参考。

It's a focus of the world to assess the structure integrity of large metal structures and long distance oil and natural gas pipelines.Many flaw assessment standards based on Fitness-for-Purpose procedure have been developed.Here we discussed the newly development and relations of several flaw assessment methods such as R6,API 579,BS 7910 and SINTAP standards.So it will be helpful to our study of pipeline assessment.
