摘　　要：结合二级管网工程案例,对PE-RTⅡ型预制保温管与传统预制保温管的经济性进行比较。方案1采用PE-RTⅡ型预制保温管,方案2采用传统预制保温管。与方案2相比,方案1的管材费降低15.0%,工程费(含土建费、安装费)降低4.2%。得益于更低的管材费、土建费、安装费,方案1的经济性更佳。Combined with a case of secondary pipe network engineering,the economy of PE-RT Ⅱ prefabricated insulation pipe is compared with that of traditional prefabricated insulation pipe.Scheme 1 adopts PE-RT Ⅱ prefabricated insulation pipe,while scheme 2 adopts traditional prefabricated insulation pipe.Compared with Scheme 2,Scheme 1 reduces the pipe material cost by 15.0%,and the engineering cost(including civil construction cost and installation cost)by 4.2%.Thanks to lower pipe fees,civil engineering costs,and installation costs,Scheme 1 has better economic efficiency.
