1 概述 西三环煤气高压线作为首都煤气管网命脉之一,多年来一直起着联系东、西两片气源的重要作用,但随着运行时间的增长(该条管线为1990年始投产运行)其管道内的各种杂质不断沉积,造成了该段管线出现多起煤气泄漏事故,已经形成了煤气管道的安全隐患。 为了彻底地消除这条管线的各种隐患问题,公司决定对该段高压线进行大修清洗处理,并对该管线进行腐蚀鉴定,确定最终的解决方案,此次工程北起六里桥高线三通,南至西三环南路高水12~#抽水缸,全长
1 Overview The Xisanhuan gas high-pressure line, as one of the lifebloods of the Capital Gas Pipeline, has been playing an important role in connecting East and West gas sources for many years, but with the increase of operating time (the pipeline was put into operation in 1990) The various impurities in the pipeline are continuously deposited, resulting in multiple gas leakage accidents in the pipeline, which has created a safety hazard for the gas pipeline. In order to completely eliminate various hidden troubles in this pipeline, the company decided to carry out overhaul and cleaning of this section of high-voltage line, and conduct corrosion identification of the pipeline to determine the final solution. The project starts from the Liuliqiao high-line three links in the north. , South to West Third Ring South High Water 12~# pumping tank, full length
