直埋聚氨酯保温管优越性综合分析

The comprehensive analysis on the superiority of direct-buried polyurethane insulating tube

介绍了直埋管的特点及施工工艺 ,对直埋聚氨酯保温管与砖砌暖沟敷设进行了经济比较 ,对其导热系数、热损失与其它保温材料及保温管道进行了比较 ,得出了在达到同样保温效果的前提下 。

In this paper the characteristic and construction t echnology of the direct?buried tube are introduced. The direct?buried polyurethane insulating t ub e and brick heating pipe's lay is compared economically, the heat conductivity c oefficient and thermal loss are compared with other heat insulator and heat tube . The conclusion is drawn that on the premise of achieving the same insulating e ffect, using polyurethane insulating direct?buried tube has more superiority.
