The natural gas city gate station, a gas pressure regulating device specially designed for the transmission and distribution station of long-distance natural gas pipelines, is the gas source station for the distribution pipeline network in cities and towns and industrial areas. Its task is to receive the natural gas transmitted from long-distance pipeline and send it to the pipe network in cities and towns or industrial areas after dust removal, filtration, heating, pressure regulation, metering and odorization.
Imported flow instruments, flow computers and domestic high-quality flow instruments can be equipped.
Imported pressure regulator and shut-off valve can be used, with the features of high pressure regulation accuracy, stable output pressure, reasonable structural design, convenient installation, use and maintenance.
Work in remote telemetry/remote control mode.
Take thermal insulation and heat mixing measures.
Select different structural forms according to user requirements.
SGS high-high pressure and high-medium pressure regulator stations, usually designed with skid-mounted structure, are widely used in the pressure regulation and stabilization of high-high pressure and high-medium pressure gas pipe networks, such as long-distance pipeline offtake stations, city gate stations, gas pipe network and gas distribution stations for natural gas.
Most of the high-high pressure and high-medium pressure regulator stations are subject to equipment selection and process design according to the parameters and working conditions provided by the user.
The main functions include: pig trap system, filtration, metering, heat exchange, pressure regulation, automatic odorization and station control system.
