浙江省生产钢丝网自应力管已有近30年的历史,被广泛地用在小水电和给排水工程中。去年安装在金华双龙水电站由新安江生产的φ350钢丝网自应力管,使用的地形高差达485米,工作压力62kg/cm~2,试压80kg/cm~2。随着本省喷灌事业的发展,它又以其省钢材、能耐压、工作可靠、寿命长不易腐蚀、不会老化、内壁年久不结污垢,安装简便,采用承插式柔性接头,管线能弧 Zhejiang Province since the production of steel self-stress tube has nearly 30 years of history, is widely used in small hydropower and water supply and drainage projects. Last year, it was installed in Jinhua Ssangyong Hydropower Station by the Xin’anjiang production of φ350 steel self-stress wire mesh, the use of terrain elevation of 485 meters, working pressure 62kg / cm ~ 2, pressure test 80kg / cm ~ With the development of sprinkler irrigation in this province, it has the advantages of steel material in its province, its ability to withstand pressure, reliable working, long life, easy corrosion, aging, long wall without dirt and easy installation. The use of socket flexible joints, arc
