The network of crude oil pipelines in the U.S. is extensive. There are approximately 55,000 miles of crude oil trunk lines (usually 8 - 24 inches in diameter) in the U.S. that connect regional markets. The U.S. also has an estimated 30,000 to 40,000 miles of small gathering lines (usually 2 to 6 inches in diameter) located primarily in Texas, Oklahoma, Louisiana, and Wyoming with small systems in a number of other oil producing states.
The larger cross-country crude oil transmission pipelines or trunk lines bring crude oil from producing areas to refineries. There are approximately 55,000 miles of crude oil trunk lines (usually 8 to 24 inches in diameter) in the United States that connect regional markets. There are also a few VERY large trunk lines.One of the largest in the U.S. is the Trans-Alaska Pipeline System, which is 48 inches in diameter.The next group of liquid petroleum pipelines is one that carries refined petroleum products â gasoline, jet fuel, home heating oil and diesel fuel.ithin the liquid petroleum pipeline network there are crude oil lines, refined product lines, highly volatile liquids (HVL) lines, and carbon dioxide lines (CO 2). Crude oil is also subdivided in to 'Gathering Lines' and âTransmission Linesâ.
