In 1863 in Pennsylvania, small - diameter wooden pipelines were built for transporting oil, as they were cheaper and less cumbersome to use than 42 - gallon [159 L] barrels moved on horse carts.
gadā Pensilvānijā naftas transportēšanai sāka izmantot neliela diametra koka caurules, pa kurām sūknēt naftu bija daudz ērtāk un lētāk nekā pārvadāt mucās ar zirgu pajūgiem.
