Abstract

The issues of using pipelines of heating networks with modern heat-insulating materials are considered. The features of calculating the estimated cost of a heating main for pipelines with insulation made of recently developed materials are indicated. The graphical dependences of the change in the specific estimated cost on the depth of laying of heat pipes with modern heat-insulating materials are presented. On the basis of the studies carried out by the method of comparison, the most promising insulating material for pipelines of heating networks has been established.
