The flange type electric heating pipe is to evenly distribute high temperature resistance wire in the high temperature resistant stainless steel seamless pipe, and densely fill the gap with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced, but also has high thermal efficiency and uniform heat generation. When current passes through the high temperature resistance wire, the heat generated is diffused to the surface of the metal pipe through the crystalline magnesium oxide powder, and then transferred to the heated part or the air to achieve the purpose of heating. The size of the flange can be changed, and the size and shape can also be changed. The flange type electric heating pipe is welded on the flange by multiple heating pipes and then heated. The production process is to coil the heating wire, weld the two ends of the heating wire with the lead rod, put the heating wire into the outer tube, add powder, shrink the tube, turn the tube, dig powder, bend the tube, weld the outer tube and the outer wire, seal the port and install the end wiring assembly.
