NOVELTY - The utility model claims a graphene heating pipeline for ground heating, relating to the field of heating pipeline, in order to solve the problem that the household floor heating generally adopts water heating way, so it is easy to generate scale after using for a long time, affecting the heat energy transmission, at the same time, cleaning is fussy; and the heating pipe of electric floor heating has limitation on the directional transmission of the heat energy; the utilization rate of the heat energy is to be improved. the outer surface of the refractory cotton base pipe is wound with a flexible heating belt; the outer surface of the flexible heating belt is coated with carbon slurry; and the inner part of the carbon slurry contains graphene material; the refractory cotton base layer pipe passes through the inner part of the heating protective sleeve; the outer surface of one side of the flexible heating belt is attached on the inner wall of the heating protective sleeve; the outer surface of the heating protective sleeve is sleeved with an outer insulating refractory cotton and a first fixed heat conducting sheet.
