管路保温层的选择与布置

实例证明：在满足保温要求的前提下，合理地选择保温材料，对双层复合保温层进行合理的布置，各自采用适宜的厚度，可使保温层费用最低。

Selection and Arrangement of the Thermal Insulating Layer to Pipeline

In the paper the transmitting heat equalion is applied to selection and arrangement of the thermal insulating layer to pipeline. Under meeting thermal insulating result, it is proved by an example that choosing rati onal thermal insulating material and arranging rational the inside and outside layer of double decker compound thermal insulating layer and adopting each suitable thickness can get the lowest cost of thermal insulating layer. It has an important practical value to the heat preservation of industrial pipeline.
