摘要
PE管在燃气管网中的应用日趋广泛,目前正在尝试性地应用于定向钻穿越。文章就其允许的曲率半径、穿越长度、防腐及回拖时所受的拉伸应力等进行了讨论与比较。
PE pipes are more extensive used in the gas pipeline network. Currently PE pipes are in trial basis in directional drilling construction. The article gives an analysis and debate on radius of curvature, length of crossing, preservation and the tensile stress suffered in dragged back.
