摘要
选取DN 100、200、500 mm热水预制直埋保温管(简称保温管),采用目标距离法,对3种规格保温管生产阶段的环境影响进行了评价。
DN100, DN200 and DN500 prefabricated directly buried insulated hot-water pipes （hereinafter referred to as thermal insulation pipes） are selected. The environmental impact in the manufacturing stage of the above-mentioned three types of thermal insulation pipes is assessed with the distance-to-target weighting method.
