太原钢铁集团尖山铁矿的两条高压长距离铁精矿浆输送管道,每条长度均为102 km,一条为φ243 mm管,另一条为φ29.7 mm管,工作压力均为10.17 MPa。除首末站外,不设中间站,线路中间也不设截断阀室。管道敷设路线13次穿越汾河,10次穿公路,路经娄烦县、古交市和太原市3地。近年来,由于地方政府对公路进行改扩建,管道所经河床变低等原因,改变了管道的敷设环境,表现为处在公路路面或公路路肩之上或裸露悬空,使管道受到被大车碾压、被车撞或被水冲断的威胁。为了保证管道的安全
Two high-pressure long-distance iron concentrate slurry pipes from Jianshan Iron Mine of Taiyuan Iron and Steel Group are each 102 km in length, one for φ243 mm pipe and the other for φ29.7 mm pipe and the working pressure is 10.17 MPa. In addition to the first stop, no intermediate station, the middle of the line is not set off the valve room. Pipeline laying routes 13 times across the Fenhe, 10 times wear roads, passing Loufan County, Gujiao City and Taiyuan 3. In recent years, due to the local government to re-expand the highway, the lower the riverbed by the pipe and other reasons, changing the laying of the pipeline environment, manifested as the road or highway shoulder above the road or bare dangling, Pressure, being hit by a car or threatened by water. In order to ensure the safety of the pipeline
