摘要
对某市燃气管网的主要失效形式进行了统计分析,提出了燃气管网的检验检测方法,并对低压庭院管道进行了开挖检测。根据有关规范建立了燃气管网的安全等级划分方法,并采用蒙德评价法建立了燃气管网单元的危险性评价方法。对低压庭院管道的安全性评价表明,采用蒙德评价法与安全等级划分方法对燃气管网的安全性评价结果基本一致。
The primary failure types of city gas pipelines have been discussed statistically. The testing and inspecting methods are put forward and adopted in low pressure courtyard pipelines by digging. The safety status classification method has been established by the safety technology criteria and safety assessment method has been given based on Mond evaluation method also. The results indicated that safety evaluation for low pressure courtyard pipelines by Mond evaluation method is accordance with safety status classification method.
