Abstract: Analyzes actual throughput of Southern Oil Product Transport Pipeline and changing law of product's storage temperature, puts forward a plan for canceling or stopping diesel tank's heating vapor at initial or terminal stations. By actual storage and transport operation on 0# diesel after stopping vapor heating and actual measurement value analysis on product's temperature in oil tank at initial and terminal stations, it is considered that vapor heating can be stopped at initial and terminal stations while transporting and storing 0# diesel so as to get a good result in energy saving and consumption cut-down.
