Flexible composite hose with self-heating constant-temperature function

The utility model belongs to the technical field of composite pipes, and particularly relates to a flexible composite hose with a self-heating constant-temperature function. The cable structurally comprises an inner core layer, a reinforcing layer, a heating layer and an outer sheath from inside to outside in sequence, wherein the heating layer is formed by winding linear or strip-shaped electric heating bodies along the pipe body or laying the linear or strip-shaped electric heating bodies in parallel with the axial direction of the electric heating bodies, the two ends of the pipe body are provided with power-on connectors connected with the electric heating bodies, and a bonding layer made of an insulating heat-conducting adhesive is arranged between the heating layer and the increasing layer. The insulating heat-conducting adhesive is heat-conducting silica gel or silicone grease. The novel composite hose has a constant-temperature heating effect, can remarkably improve the flowing efficiency of viscous f
