摘　　要：统计分析了克乌复线529×7(8)mm管道全线腐蚀缺陷的漏磁检测数据与现场取样管段室内缺陷尺寸测试数据。对腐蚀缺陷在管道全线的分布情况及特征进行了分类统计,并结合室内测试结果,按里程进行了综合分析。将其结果与剩余强度评价结果相结合,为管道防腐层维修和管段的维护提供决策依据,有利于管道的科学管理和运营。The detection data of corrosion defects gained by leakage magnetic detector and laboratory test data ofdefect dimensions of pipe samples, taken on site which picks up on Kelamayi——Wulumuqi parallel oilpipeline (φ529×7(8)mm) ,are statistically analyzed. The distribution of corrosive defects along the whole line and their characteristics have been statistically classified,and a comprehensive analysis on defect frequency/pipeline kilometer has been made,combined with laboratory test results. The authors consider that the final analysis results, which is from the statistics and evaluation report on residual strength of the pipeline,will be helpful for decision making on the rehabilitation of coating or maintenance of pipeline, which is beneficial to the scientific management and operation of the pipeline.
