摘要: 基于多源数据对齐的管体缺陷综合分析已成为管道完整性评价工作的重要组成部分。以华中地区某成品油管道为研究对象,整合了内检测、外检测、开挖验证、河流穿越、高后果区以及重点关注管段等多源数据,开展了数据对齐及综合分析,掌握了该段管道的总体完整性状况,识别出了管道的活性缺陷点和异常焊缝,进行了关键位置缺陷的致因分析,并为下一轮内检测和风险消减提出了针对性建议,有效保障了该管道的安全运行。Abstract: Comprehensive analysis of pipe defects based on multi-source data alignment has become an important component of integrity evaluation for pipeline. Taking a product oil pipeline in central China as the research object, this paper integrated that multi-source data of product oil pipeline including internal and external inspection, excavation verification, and some information about river crossing, high-consequence area and other key pipeline sections, the data alignment and comprehensive analysis were conducted, the overall integrity of this section of pipeline is thoroughly understood, active defect points and abnormal welds of the pipeline were identified, and the causes of defects at key locations were analyzed. The targeted recommendations for the next round of inspection and risk reduction were provided to effectively ensuring the safe operation of the pipeline.
