The thesis is devoted to the study of the problem of the irrational use of the heat-insulating layer in the channel laying of pipelines in impassable channels. All thermal resistance to the heat flux of various components of the heating main are determined. The estimated payback of heat-insulating layers of various thicknesses is predicted. The most optimal thickness of the insulating layer was revealed. To more accurately determine the heat loss of pipelines in a non-passage channel, a cross-sectional model of a heating main has been built in ANSYS®. The mode of free convection inside the channel is revealed. The velocity and temperature distribution fields are simulated for grids of various quality with various turbulence models.
