Underground gas piping should be installed with sufficient clearance from any other underground structure to avoid contact, to allow for maintenance, and to protect against damage from proximity to other structures.
How is natural gas transported?
Transporting natural gas from production areas to consumers involves a series of steps that are generally carried out in the following order: 1 Gathering systems, primarily made up of small-diameter, low-pressure pipelines, move raw natural gas from the wellhead to a natural gas processing plant or to an interconnection with a larger mainline pipeline. 2 Natural gas processing plants separate hydrocarbon gas liquids, nonhydrocarbon gases, and water from the natural gas before the natural gas is delivered into a mainline transmission system. 3 Wide-diameter, high-pressure interstate transmission pipelines that cross state boundaries and intrastate transmission pipelines that operate within state boundaries transport natural gas from the producing and processing areas to storage facilities and distribution centers. Compressor stations (or pumping stations) on the pipeline network keep the natural gas flowing forward through the pipeline system. 4 Local distribution companies deliver natural gas to consumers through small-diameter, lower pressure service lines.
Why was natural gas installed in the 1950s?
About half of the existing mainline natural gas transmission network and a large portion of the local distribution network were installed in the 1950s and 1960s because consumer demand for natural gas more than doubled following World War II.
What is a wide diameter interstate pipeline?
