Intelligent electromagnetic-induction heating band for pipeline

The utility model relates to the technical field of preheating thermal insulation of pipeline welding junctions, especially to an intelligent electromagnetic-induction heating band for a pipeline. A heating cable of the heating band is made of a rare earth alloy material, and connected with binding posts, a magnetic field isolating material is arranged in the middle of the heating cable, the heating cable and a heat insulation layer are fixed by bakelite-board fixing devices for an electric heating coil, a glass fabric tape is wound around the heating cable and the heat insulation layer, and one end of a fastening buckle is arranged on the heat insulation layer and wound by the glass fabric tape. The intelligent electromagnetic-induction heating band for the pipeline realizes highly-efficient, energy-saving, safe, economical, practical and intelligent temperature control, is portable, improves the welding efficiency, and solves the disadvantages of a present heater including high consumption energy, low safet
