Type A stations are those which reduce the gas (which is in the high pressure class) at 35-70 bar pressure to 12-25 bar in the main steel line. After the gas pressure in RMS-A is reduced, it is sent to distribution lines.
The main functions of A Type stations are as follows:
Regulating the station’s outlet pressure,
Metering of gas flowing through the station,
Regulating the heat of the gas flowing through the station.
