Pipeline Natural Gas Distributing Facilities
1. Gas Distributing Station
Gas distributing station is the station which transmits natural gas from the national or provincial gas transmission network to the downstream. The gas distributing station can transmits natural gas to one or more city gate station. It usually has the functions of trade measurement, filtration separation, heating, pressure regulating, flow controling and etc. The configuration of the gas distributing station has the features of high pressure, high precision, high-performance and etc. The regulator is usually in the form of a regulated train. Metering generally use high-precision ultrasonic flow meter.

2. Natural Gas Gate Station
City gate station is the key link that transmits gas from the long-distance pipeline into the city pipe network. It is generally connected directly with the gas distributing station. It is the first stop of the town gas downstream. The skid-mounted city gate station our company designed and produced integrates gas and dust separation facility, gas filter device, pressure regulation, flow measurement and regulation, gas heating, odoring, remote control and communication and many other equipment and technology to achieve a large gas transmission equipment integrated.
