摘　　要：针对在役油气输送管道体积型缺陷评定问题,重点分析了我国现有的两个缺陷评定规范的特色和创新点,并进行了对比。对比分析结果显示,《在用含缺陷压力容器安全评定》规范方法简单,运算简便,适用缺陷类型广,易于掌握和操作,应为缺陷评定首选执行标准。采用该规范对一案例进行评定,评定结果显示,缺陷的存在是安全可接受的。Considering the volumetric defects assessment for in-service pipelines,the two China codes for defects assessment were analyzed and compared.Comparison and analysis results show that the Safety Assessment for In-service Pressure Vessels Containing Defects outperforms others in the calculation and application scope and operation.Taking it to assess the pipeline defects shows that some defects can be permitted.
