▎ 摘　　要

NOVELTY - The pipe (100) has an insulated pipe portion (101) and a graphene layer (102). The graphene layer is attached to an outer surface of the pipe portion. A first electrode (103) and a second electrode (104) are respectively provided at two ends of the pipe portion, and the first electrode and the second electrode are both electrically connected to the graphene layer. The first electrode and the second electrode are used to connect an external power source. The graphene layer is used to generate heat when the absolute value of the voltage difference between the first electrode and the second electrode is greater than an activity threshold, so as to heat the medium flowing in the pipe portion. USE - Heating pipe for use in heating device (claimed). ADVANTAGE - The pressure difference across the graphene layer causes the graphene molecules to collide to generate heat, thus, heating the medium in the pipe portion, the heating effect is good, and no waste is generated, which saves energy and protects the environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a heating device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a heating pipe.
