摘　　要：在役压力管道安全可靠运行是目前世界各国油气储运业界普遍关注和迫切需要解决的重大课题，而在役压力管道腐蚀剩余强度评价则是为保障在役压力管道安全可靠运行的基础工作，其评价结论直接为管线运行的操作工艺、运行参数提供理论依据，同时指导管道安全生产管理。文章简述国内外在役压力管道腐蚀剩余强度评价工作进展情况，然后着重介绍西南油气田分公司长输管道检测中心对龙苍线、佛两线、克乌线及濮临线等多条油气输送管道进行剩余强度综合评价的方法和经验，包括不同形貌即平百性、体积性缺陷定量及剩余强度评价方法。The safe and reliable operation of in-service pressure pipeline is a significant topic which is in urgent need of solution and is followed with interest by the oil and gas storage-transportation circles in every country of the world at present, and yet the evaluation of residual corrosion strength of in-service pressure pipeline is a fundamental work for guaranteeing its safe and reliable operation, It' s evaluation results provide a theoretical basis directly for determining pipeline operation technology and parameters and may be used for guiding pipeline's safety in production management. On the basis of simply stating the works of evaluating the residual corrosion strength of in-service pressure pipline at home and abroad, the method and experience of comprehensively evaluating the residual corrsion strength for several oil-gas transmission pipelines, as the Long-Gang, Fu-Liang, Ke-Wu and Pu-Lin pipelines, by the Long-distance Pipeline Detection and Evaluation Centre of the Southwest Oil and Gas Field Branch Co. including the defect quantity of various(Planar and volumetrical) shapes and residual strength evaluation method,are emphatically introduced in the paper.
