The utility model provides a detachable low-voltage electric heat tracing system. Relates to the technical field of oilfield pipeline heat tracing. A heat conduction layer is arranged on the inner side of the heat preservation layer, an electric heating belt is laid on the outer side of the heat conduction layer, the electric heating belt is electrically connected with power lines, the power lines are sleeved with insulating sleeves, and after the two end faces of the heat preservation layer are curled and combined, the two power lines are located at the combination positions of the two end faces of the heat preservation layer and connected together through fasteners. The heat-preservation tracing pipe has the advantages that the heat-preservation tracing pipe suitable for various nominal drift diameters is prefabricated according to the specification of a pipeline, the length is certain, batch production can be achieved, the manufacturing cost is reduced, in the installation process, the combination face of
