The US natural gas pipeline system is a complex system of pipelines that carries natural gas nationwide and for import and export for use by millions of people daily for their consumer and commercial needs. Across the country, there are more than 210 pipeline systems that total more than 305,000 miles of interstate and intrastate pipelines. [ 1]
Utility locator tool in use (Perry, Oklahoma, 2011) Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication, electricity distribution, natural gas, cable television, fiber optics, traffic lights, street lights, storm drains, water mains, and wastewater pipes.
A seismic earthquake valve operating at a pressure of 55 psig (3.7 bar) can stop the flow of natural gas into the site wide natural gas distribution piping network (that runs (outdoors underground, above building roofs, and or within the upper supports of a canopy roof).

Pipe marking on a natural gas pipe. In the process industry, chemical industry, manufacturing industry, and other commercial and industrial contexts, pipe marking is used to identify the contents, properties and flow direction of fluids in piping. It is typically carried out by marking piping through labels and color codes.
The first hundred miles of pipe began to be laid in September 1930. [9] The pipeline was completed on August 29, 1931, and gas began moving on September 1. [5] It was the first 1,000-mile pipeline built in the United States, [10] and the first high-pressure, thin-walled, electrically-welded, cross-country pipeline. [11]
Maximum Allowable Operating Pressure ( MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula, which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...
In 2012, the United States produced 25.3 trillion cubic feet of marketed natural gas, with an average wellhead value of $2.66 per thousand cubic feet, for a total wellhead value of $67.3 billion. [ 2] In 2013, the country produced 30.0 trillion cubic feet (TCF) of marketed gas. [ 3] With 7,545 billion cubic feet (BCF), the leading gas-producing ...
