Abstract

The invention relates to a heating sleeve for pipes, comprising an outer jacket, a heat insulating layer and a flat resistance heating element positioned on the internal side of the heat insulating layer. The resistance mass of the resistance heating element comprises an intrinsically electroconductive polymer and the power supply lines of the electrodes of the resistance heating element are guided through the heat insulating layer of the heating sleeve.
