On average, main gas lines are usually found at least 24 inches deep, while service lines are usually 18 inches deep.
How deep is a petroleum pipeline buried?
about 3 to 6 feet
Most pipelines are typically buried at a depth of about 3 to 6 feet (0.91 to 1.83 m). To protect pipes from impact, abrasion, and corrosion, a variety of methods are used.

How deep should a gas line be?
How Deep Does A Gas Line Have To Be Buried? Generally the depth of your ditch should be 18 to 24 inches. The type of terrain will have something to do with the depth. Always check with your local building department for specific code regarding depth of your ditch in your area.
Do pipelines go underground?
Pipelines exist throughout the country, and they vary by the goods transported, the size of the pipes, and the material used to make pipes. While some pipelines are built above ground, the majority of pipelines in the U.S. are buried underground.
Are underwater pipelines buried?
These submarine pipelines encounter significant dynamic forces due to the action of waves and currents. In order to reduce such forces and associated risk of failures, they are recommended to be buried below the seabed. The dynamic seepage force Page 2 exerted on the pipeline is computed.
How many oil pipelines are in the ocean?
California, with just a fraction of the offshore oil and gas infrastructure as the Gulf of Mexico, could be a harbinger of things to come. In the Gulf, leaks frequently spring from a tangle of more than 8,600 miles of pipelines, many of them abandoned, and more than 1,800 platforms.
