The invention discloses a heatable pipeline for liquid conveying, and belongs to the technology of pipeline heating. The pipeline is characterized in that a fluid heat transfer device is installed in a cavity of the pipeline; the axial direction of a tubular heat source supply component is parallel with that of the pipeline; the fluid heat transfer device comprises the tubular heat source supply component and a slabby heat pipe; one end, which is along the heat conduction direction of the heat pipe, of the slabby heat pipe is connected with the outer wall of the tubular heat source supply component in a heat transfer way, and the other end of the slabby heat pipe serves as a free end; the connection in a heat transfer way indicates that the slabby heat pipe is directly connected with the outer wall of the tubular heat source supply component; the slabby heat pipe is a slabby heat pipe disclosed in the China Patent 200910207418.9 or the divisional application 201110309983.3 thereof. The pipeline is used for liquid conveying, can properly heat liquid, and is particularly applied to the conveying of liquid easy to solidify.
