The paper considers the problem of reducing heat losses in the heat supply systems of the FEC facilities (fuel and energy complex) due to the the use of heat insulation of the pipelines. A comparative analysis of heat insulation of the heat lines: PUF (polyurethane foam), mineral wool, foam rubber, ultrathin heat insulation of the mark “Corund”. The graphical dependences of heat losses and the efficiency factor of heat insulation on a diameter the pipelines are obtained.
