The long transportation pipeline includes several natural gas stations. The so-called natural gas station is used to distribute natural gas from long-distance pipelines. Its downstream is generally distributed to one or more city gate stations. The main function is to filter, meter and regulate the natural gas in places where natural gas is needed to ensure daily gas supply. Some natural gas stations also have pressurization functions. In order to ensure the safe operation of natural gas stations, safety inspections are required.
