埋地管道运输有便利、经济、安全、环保、使用年限长等优点,所以在世界各国有着广泛应用。近年来管道增多、管龄增长,泄漏事故不断发生,造成资源浪费和环境污染。随着科技进步及国家相关法令的出台,管道使用单位对管道的安全性能越加重视。经过对旧管道的修复、修理及更换方案的比较发现有计划的修复比事故后的修理代价小得多,有效地避免了恶性事故,提高了社会效益和经济效益,因此开展埋地管道监测与检测技术研究具有十分重要的现实意义。对埋地管道泄漏的探测分为监测和检测2种技术。埋地管道泄漏监测主要是对管道从不漏到突
Buried pipeline transportation is convenient, economical, safe, environmental protection, long service life and so on, so in all countries in the world has a wide range of applications. In recent years, pipelines have grown, pipe age has increased, and spill accidents have taken place continuously, resulting in waste of resources and environmental pollution. With the progress of science and technology and the introduction of relevant state laws and regulations, the pipeline users pay more attention to the safety performance of the pipeline. After comparing the rehabilitation, repairing and replacement schemes of old pipelines, it is found that the planned repairs are much smaller than the repairs after the accident, effectively avoiding the vicious accidents and increasing the social and economic benefits. Therefore, the monitoring of buried pipelines and Testing technology research has very important practical significance. Buried pipeline leak detection is divided into two kinds of monitoring and detection technology. Buried pipeline leak monitoring is mainly from the pipeline never leak suddenly
