City Gate Station

This series of pressure regulating stations is usually skid-mounted. Served as the key of supporting the gas long-distance transmission pipeline into the city pipe network, the equipment mainly applies to the branch station of the gas long-distance transmission pipeline as well as the downstream of the first station or the upstream of the city medium pressure network as the city gate station.

The pressure regulation and stabilization of the high-high and high-medium pressure gas networks of the gas distribution station, CNG station, etc. of the gas networks have functions such as purification, metering, pressure regulation, distribution and safety protection. The equipment can also be configured with gas alarm system, automatic control system and odorization system according to the user’ s requirements, and can also be configured with optional RTU unit and communication unit.

At the same time, the gate station is equipped with a smart gas multi-functional acquisition remote transmission terminal, which is used in the intelligent test center system, making full use of the SCADA data acquisition control system to conduct real-time detection of various remote transmission instruments in the pressure regulating station, and comprehensively conduct all data on the equipment. It collects, records, analyzes and automatically transmits and saves data. The data can be transmitted externally in real time. It can meet the functional requirements of the one-code traceability data collection terminal required by the gas company. It can also be equipped with an optional RTU unit and communication unit.
