摘　　要：为满足相关规范中对管道保温层外表面温度以及对绿植影响和管网热损失方面的要求,文章研究了具体的供热官网工程,计算了相关理论厚度,并对该厚度进行了验算。经计算,在所举例的工程条件下,设计管中心埋深2.2m、供水管保温层厚度为100mm、回水管保温层厚度为60mm的供热管道保温层可满足要求。In order to meet the requirements of relevant specifications for the external surface temperature of pipeline insulation layer,the impact on green plants,and the heat loss of pipeline network,the article studied a specific heating official website project,calculated the relevant theoretical thickness,and checked the thickness.After calculation,under the example engineering conditions,the insulation layer of the heating pipeline with a buried depth of 2.2 meters,a thickness of 100 mm for the insulation layer of the water supply pipeline,and a thickness of 60 mm for the insulation layer of the return pipeline can meet the requirements.
