Gas Supply Station

There are several different types of gas distribution stations, each for a different purpose: stations on the branch of a main gas pipeline having a capacity of 5,000-10,000 to 300,000-500,000 cu m per hour; gas distribution stations for processing gas extracted from a gas field and also for supplying gas to populated areas near the gas field; control-and-distribution points located on branches from main gas pipelines to industrial and agricultural destinations and also for supplying a ring system of gas pipelines around a city automatic gas distribution stations for delivering gas to small populated area.

Gas distribution stations on main gas pipelines reduce the initial gas pressure (for example, 5 meganewtons [MN] per m2, that is, 50 kilograms-force per cm2) according to a single-, double-, or triple-stage arrangement, down to 0.1 MN/m2 or less. In an automatic gas-distribution station the pressure is reduced from 5.5 to 3·10—2 MN/m2. At gas-regulating points a high pressure (1.2 or 0.6 MN/m2) is lowered to a medium pressure (0.3 MN/m2) or a low pressure (300 mm of water gage).
