Abstract: Golmud-Lhasa products pipeline was designed to transport in batch gasoline, jet fuel, illuminating kerosene, and diesel oils (- 35^# and - 20^#). With the economic development in Tibet, the demand for - 10^# diesel oil is increasing because of its low price and potential economic benefit. As a result, it is considered to transport -10^# diesel oil by Golmud-Lhasa pipeline. After analysing the atmospheric temperature, ground temperature and wind velocity along pipeline route and on the temperatures of the incoming and outgoing oil at pump stations, it is believed feasible, by duly'adjusting operating parameters, to transport - 10^# diesel oil in every August and September, when the oil passing through frozen soil zones can maintain above 5℃.
