在役油气输送管道体积型缺陷安全评定方法

摘要

Considering the vodumetric defects assessment for in-service pipelines, the two China codes for defects assessment were analyzed and compard, Comparison and analysis results show that the .Safety dssessment for In-service Pressure Vessels Containing Defects outperforms others in the calculation and application scope and operation, 'Taking il to assess the pipeline defects shows that some defects can be permitted,%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.
