摘　　要：管道检测和维修能使呈“浴盆”状的管道事故曲线的低概率部分加宽,从而降低管道事故。根据管道缺陷的不同,提出了不同的检测和监视方法,用这些方法可进行管道危险评价,包括正在腐蚀的管道评价、管道缺损评价等。叙述了管道在线检测应考虑的问题及在线检测实际费用。强调使用名副其实的高分辨率管道检测器和进行专门的合理的管道缺损评价的重要性,优化的未来管道安全运营战略所节省的费用完全可以补偿管道检测和管道缺损评价所需费用。The inspection and maintenance of pipelines will help to extend the low probability of the pipeline failure curve with a 'bath tub' shap,which can reduce pipeline failures. Some inspection and monitoring methods have been set forth according to different pipeline damages. With these methods,the risk assessment of pipelines can be made, including a corroding pipeline assessment and pipeline damage assessment. It describes the problems of in-line inspection to be considered and the costs,and highlights the importance of using genuine high-resolution pigs for the inspection,the cost savings on the optimised future safe operating strategies for the pipeline offset costs of the inspection and expert assessment.
