Even electric heat tracing pipe of thermal field

The utility model relates to an industry electric tracing technical field is an even electric heat tracing pipe of thermal field. Including the conveyer pipe, be provided with 3 strip metal braid over braids along axial direction on the surface of conveyer pipe, the braid over braid is connected with three phase current's electrode respectively, be provided with a plurality of electro -heat equipment between the braid over braid, braid over braid and electrothermal welding parcel have the first insulation layer. Be provided with the second insulating layer between conveyer pipe and the braid over braid. Braid over braid equidistance interval sets up. Electro -heat equipment evenly arranges on the surface of conveyer pipe. The utility model discloses as long as even connect with the mains just passablely, consequently the installation is more convenient, in addition, sends out an electro -heat equipment and arranges evenly on the body that being heated of body is more even, can not lead to the fact the too hig
