根据实践经验，对球墨铸铁管、钢塑复合钢管及 PE 给水管进行了管道水头损失及管材费用、防腐性能、物理性能等方面的比较，通过对比研究，得出钢塑复合钢管用于再生管道工程中具有较好的防腐、节能效果，值得推广应用。%According to practical experience,the paper compares nodular cast iron pipe,steel reinforced composite pipe and PE water-supply pipes from aspects of pipe water source damage,pipeline material cost,anti-corrosion performance,and physical performance and so on,and concludes that:the application of steel reinforced pipe in recycled pipeline engineering has better anti-corrosion and energy-saving effects,which is worth promoting.
