我国第一批大口径(φ1600mm和φ2600mm)嵌置式预应力钢套筒混凝土压力管于1990年12月5日～7日在山东省电力线路器材厂通过部级鉴定。嵌置式预应力钢筒混凝土管与钢管相比可节约钢材60％、造价降低10％左右,并且具有承受压力高、无污染、使用寿命长、抗渗性高等优点,是理想的非金属输水管材,可广泛用于城市输水,排污、水利、水电以及核工业的引水工程。
China’s first batch of large diameter (φ1600mm and φ2600mm) embedded prestressed steel sleeve concrete pressure pipe on December 5, 1990 to 7 in Shandong Province, the power line equipment factory through the ministerial identification. Compared with steel pipe, embedded prestressed concrete-in-steel pipe can save 60% of steel and reduce the cost by about 10%, and has the advantages of high bearing pressure, no pollution, long service life and high impermeability, and is an ideal non-metal water delivery Pipe can be widely used in urban water, sewage, water conservancy, hydropower and nuclear industry diversion project.
