摘要
随着上海城市燃气事业的进一步发展,尤其是天然气逐步进入上海市区,燃气客户的不断增加,大口径中压燃气主管道镶接分支管的施工日益频繁。对运行中的大口径中压燃气主管道上采用封闭式钻孔机不停气镶接分支管工艺的应用进行探讨。
With the further development of Shanghai city gas industry, especially the phenomenon that natural gas enters Shanghai downtown area step by step and the continuous increasing of gas clients, the big inch medium pressure main gas pipe hatched grafting branch pipe constructions become high frequency. The article discusses the closed type drill in non-stop transmission hatched graining technics application in those constructions.
