The utility model relates to a heat-shrinkable tape, in particular to a heat-shrinkable tape for repairing a pipeline coating, which comprises a heat-shrinkable tape and a marker line, and the marker line is arranged on the surface of the upper end of the heat-shrinkable tape. The thermal contraction band overcomes the defects in the prior art, by arranging the marker line, when a worker measures the length, needing to be repaired, of a pipeline, the pulling length of the thermal contraction band for repairing the pipeline coating is measured through the marker line, and therefore the length of the thermal contraction band for repairing the pipeline coating does not need to be measured through a measuring scale; and when the length is the whole meter, a cutting tool can be used for cutting along the marking line, so that the cutting flatness of the heat shrinkage belt for repairing the pipeline coating can be improved, the fitting degree between the heat shrinkage belt of the repairing material and the pipeli
