What do you know about Pipelines? Pipelines are energy lifelines, making almost every daily activity possible. Pipelines play a huge role in everyday lives and are essential to the nation's industries. Yet, few people are aware of the work done by the country's more than 190,000-mile liquid petroleum pipeline network and 2.4 million-mile natural gas pipeline network that delivers the products that are integral parts of America's economy. It is a network that delivers the nation's crude oil and petroleum products (such as gasoline, diesel, jet fuel, home heating oil, and natural gas) reliably, safely, efficiently, and economically.
