Yang Hongbin Ji Yuyu)Abstract: The calculation of the flow in city gas pipeline transmission and distribution system is related to the economy and reliability of network system. Takes No. 9 building of Jinliyuan Baoji City as an example, this paper calculates the gas consumption of appliances using the simultaneously coefficient method and index of heating method, respectively. In addition, the effect of different calculation methods on the selection of the diameter of gas lowpressure overhead pipeline is studied.Key words: gas pipeline。 heating index。燃?xì)夤こ淘O(shè)計要在安全便利、實用可行、美觀舒適的基礎(chǔ)上提高其經(jīng)濟(jì)性,即在規(guī)范
