[6] Gas plants could be sited within cities, and many major U.S. cities such as New York, Chicago, San Francisco had gas distribution lines for manufactured gas by the ...
Natural gas may move through a pipeline system typically at speeds of up to 25 mph (11.2 m/s), depending on pressures and pipeline diameters. For a pipeline system operating at a nominal pressure of 1000 psi (such as the UK National Transmission System ) compressor stations compress the gas from about 48 bar (700 psi) to 65 bar (950 psi).
NGPL traces its history to the Continental Construction Corporation, which changed its name to the Natural Gas Pipeline Company of America in December 1931.

However, permanent marker signs are used for utilities like hydrants, drinking water lines and natural gas lines.
