天然气高压管道不停输带气封堵技术的应用

Application of Gas Plugging Technology in Non-stop Gas Transmission Belt of High Pressure Natural Gas Pipeline

结合近年来国内城市高压天然气管道迁改的建设实践,介绍了高压天然气管道迁改完成后不停输带气封堵实施新旧管道接驳的施工技术,对今后城市高压天然气管道迁改完成后采用不停输带气封堵方式实施新旧管道接驳具有一定的指导借鉴意义。

Based on the construction practice of high-pressure natural gas pipeline relocation in China in recent years,this paper introduces the construction technology of connecting the old and new pipelines after the completion of high-pressure natural gas pipeline relocation without stopping the gas transmission,which has certain guiding significance for the future implementation of connecting the new and old pipelines with the method of non stopping the gas transmission after the completion of urban high-pressure natural gas pipeline relocation.
