在输气管线设计中,为了调整压缩机站数以及增加管线的输量,常需在管线中敷设一定长度的副管或变径管。本文从金属耗量出发,论述所需副管与变径管的金属耗量与
In the design of gas transmission pipelines, in order to adjust the number of compressor stations and increase the output of pipelines, a certain length of auxiliary pipe or reducer pipe is often laid in the pipeline. This article starts with the metal consumption and discusses the metal consumption of the required secondary pipe and reducer pipe.
