In the United States there are approximately 333,000 miles of pipe line transporting crude oil, refined products, and natural gas, built at an estimated cost of $3,200,000,000, which provide this nation with an underground transportation system that is a marvel to the rest of the world.

Today there are approximately 133,000 miles of pipe lines carrying crude oil and refined products and approximately 200,000 miles of natural gas lines. On this system of underground pipe lines serving virtually every city and industrial center in the country, it is estimated there...
