[0002] A natural gas transmission pipeline refers to a pipeline that transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. In order to prevent pipeline damage and facilitate the determination of pipeline damage locations, natural gas transmission pipelines with flow rate detection are usually installed between pipelines.

When internal components are damaged and need to be repaired, the entire transmission pipeline needs to be cut off to prevent the transmission of natural gas. The operation is relatively cumbersome, resulting in low maintenance efficiency and affecting the transportation of natural gas. Utility Model Content
