Abstract: An apparatus for heating a pipe is disclosed. An apparatus for heating a pipe configured to heat a pipe line by covering the pipe line, which comprises: an inner sheet covering the pipe line in such a way that one surface thereof faces an outer surface of the pipe line; a heating wire distributed on the other surface of the inner sheet; an insulation pad stacked on the other surface of the inner sheet and configured to insulate heat emitted from the heating wire; and stitches configured to fix the heating wire to the inner sheet or the insulation pad, can simplify the configuration and manufacturing process of the apparatus for heating a pipe.
