Description

Natural gas pipeline leakage detection equipment Technical Field The utility model relates to the technical field of natural gas leakage detection equipment, in particular to natural gas pipeline leakage detection equipment. Background The natural gas pipeline refers to a pipeline for conveying natural gas (including associated gas produced by an oil field) from a mining place or a treatment plant to an urban gas distribution center or an industrial enterprise user, is also called a gas pipeline, is a mode for conveying a large amount of natural gas on land by utilizing the natural gas pipeline, and is about half of the total length of the pipeline in the world, and the leakage of the natural gas can cause resource waste and certain accidents, so that the pipeline needs to be detected.
