摘要
Abstract
Starting from the three stages of pipeline op-eration,the causes of leakage in courtyard gas pipe-lines,categorizing them into design flaws,third-party damage,natural corrosion,construction errors,and pipe material issues were analyzed.Targeted preven-tive measures are proposed for each identified cause of leakage.Some methods for detecting and locating leaks in courtyard gas pipelines are put forward.Five com-monly used leakage detection methods are introduced,along with one emerging detection method:vehicle-mounted leakage detection technology.The emergency repair methods for courtyard gas pipelines are also presented,namely the hot-tapping plugging method and the non-hot-tapping plugging method.The emergency repair schemes for medium and low-pressure courtyard gas pipeline leaks are proposed.关键词
