摘要
为了减少管道事故及为后续的完整性评价提供依据,文中按照相关标准的要求,对天然气管道应用ECDA方法进行了检测,发现了许多管道异常点,对发现的严重异常点进行了开挖处理。建议对其他异常点进行监测,并有序进行开挖处理。
In order to reduce the pipeline accident and provide the basis for the integrity of the follow-up evaluation, the method of ECDA was used to inspect gas pipeline according to the correlation standards. Some pipeline anomalies were found, and the serous anomalies was excavated. It was advised that the other anomalies were monitored and excavated in a well- organized way.
