Natural gas pipeline system in the United States

[1] Of the lower 48 US states, those with the most natural gas pipeline running through them are Texas (58,588 miles), Louisiana (18,900), Oklahoma (18,539), Kansas (15,386), Illinois (11,900) and California (11,770).

The Federal Energy Regulatory Commission reviews and authorizes the operation of the interstate natural gas pipelines.

[9] Just after World War II, demand for natural gas increased, and so did the development of pipelines to new markets on the West Coast in California and in the Southeastern states.

[11] In 1885, Solomon Dresser patented a new coupling that was an important advancement in engineering pipeline, making it possible to assemble longer, less leaky pipes that were easier to screw together.

[13] At the end of 2008, the U.S. had 305,000 miles of natural gas interstate and intrastate transmission pipelines in the lower 48 states.

[11] Transmission pipelines are generally 6 to 48 inches (15 cm to 1.2 m) in diameter, made of strong carbon steel or advanced plastic;[16] the largest diameters are for intrastate and interstate transmission lines, that channel natural gas into smaller mains, and service lines.

This analysis excludes the casualty figures from the 2010 San Bruno pipeline explosion that killed 7 people and injured more than 50 others.
