摘要
以珠江三角洲城市输气管网设计为例,对城市输气管网的设计问题进行了归纳。城市输气管网具有分输点多、支线多、分输量大的特点,分析了修建输气管道支线对工程投资的影响,指出在需增压输送时,压缩机站的位置选择直接影响着工程投资和经济效益。对于分期建设的工程,干线距离在300 km左右的输气管道,在工程投资方面,适当增加管径优于增设压缩机站。
Taking a design of city gas transmission network in the Pearl River Delta for example, concludes design problems in city gas transmission network. As city gas transmission network has a characteristics of multi-distribution points, multi-branches and large quantity of distribution volume, analyzes the effect of engineering investment on building gas transmission pipeline. Points out that if booster transmission is required , location selection of compressor station will affect engineering investment and economic benefit directly. For the project build by stage and the trunk line about 300 km in length, increases pipe diametei properly is superior over increasing number of compressor stations in the aspect of engineering investment.
