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 magnetic flux leakage testing data of the 529 × 7 (8) mm pipeline on the Ke’u double track and the test data of the indoor defect size of the sampling pipe section were statistically analyzed. The distribution and characteristics of corrosion defects in the whole pipeline were classified and statistically analyzed. Combined with the indoor test results, the comprehensive analysis was carried out according to the mileage. Combining the results with the evaluation results of residual strength provides decision-making basis for pipeline coating maintenance and pipe segment maintenance, which is in favor of scientific management and operation of pipelines.
