城市燃气管道设计方法比较

Comparison of Design Methods for Town Gas Piping

与长输燃气管道相比,城市燃气管网具有自己的特点,这需要在建设城市管网的过程中采用不同的设计方法。对概率性设计方法、极限压力设计方法、应变极限状态设计方法三种城市管道设计方法进行讨论,并针对每种方法如何进行计算进行介绍。

Compared with long transportation gas pipeline, the piping net for town gas has its own features, so that, it is necessary to use different design method. In this article, three design methods for town gas piping net, that are probability method, limit pressure method and strain limit method, were discussed, and the application of each method in the calculation was also introduced.
