Performs well under pressure. Compressor stations along the pipelines keep the gas moving.
Natural gas is pushed along our pipelines at a pressure of about 70 bar. The average flow velocity is 8 m/sec or about 28 kpm. Due to friction and changes in elevation, the gas steadily loses pressure and thus speed. Because of this, compressor stations are located at intervals of 70–200 km to maintain a constant flow.
