NOVELTY - The utility model belongs to the technical field of industrial electric heat tracing, specifically to a graphene flexible electric heating belt, comprising a textile fibre insulating belt; the radial direction of the textile fibre insulating belt is provided with several graphene fibre conductive belt; the axial direction of the textile fibre insulating belt is provided with two groups of metal current carrying belt; two groups of metal current carrying belts are respectively located at two sides of the axial direction of the textile fibre insulating belt; two sides of each graphene fibre conductive belt are respectively crossed with two groups of metal current carrying belts; forming multiple current loops; further comprising a silica gel insulating protective layer; the silica gel insulating protective layer is set on the outer layer of the textile fibre insulating belt, graphene fibre conductive belt and metal current carrying belt. The utility model forms a plurality of parallel heating loop from the structure, even if one or several loops are damaged or fault occurs, only the local heating is affected, the other part of the whole heating surface will normally output and generate heat needed by the heat tracing system; it can ensure normal operation of the heat tracing system.
