In 1958, The first U.S. interstate pipeline for the transport of ethylene was placed in service between Lake Charles, Louisiana and Orange, Texas. The 6-5/8" pipeline ran 30 miles, providing ethylene to the E.I. duPont de Nemours & Company at Orange for the manufacture of synthetic rubber. There are now many hundreds of miles of ethylene pipelines stretching across 14 counties in Texas and two parishes in Louisiana. They link the ethylene producer with a number of chemical manufacturers and storage facilities utilizing underground salt domes or wells. Ethylene is also manufactured into polyethylene products for many uses, including consumer goods, housing components or vehicle parts.*
