Process flow

The process flow is as follows: the natural gas is introduced from the high-pressure pipeline of Qinglin Road at the South Gate Station. After entering the entrance station, the natural gas is sent to the medium-pressure pipe network of Caofeidian SME Park after odorization, filtration, metering and pressure regulation to 0.35MPa, to supply gas for users in Caofeidian SME Park.
