The flange heating pipe includes flange, and the flange heating pipe includes the first and the second electric heating pipes which are set independently and intersected with each other. The first and the second electric heating pipes are composed of two vertical sections and transition sections connecting the two vertical sections. The vertical section is fixed vertically on the upper end face of the flange and the end of the flange passes through the flange and is fixed with the flange. The tube is arranged outside the first electric heat pipe, and the height of the transition section of the second electric heat pipe is higher than that of the transition section of the first electric heat pipe. The flange heating pipe manufacturer adopts the flange heating pipe of this scheme. The water flow can pass through the gap between the first heating pipe and the second heating pipe. It can avoid heat concentration, accelerate the efficiency of heat conduction, reduce the time needed for water heating, prolong the service life of the heating device, and has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, and simple installation. 。

Medium-temperature mechanical flange-proof heating pipe distributes high-temperature resistance wires evenly in seamless high-temperature stainless steel tube, and fills in the void part compactly with crystalline magnesia powder with good thermal conductivity and insulation performance. This structure is not only advanced, but also has high thermal efficiency and uniform heating. When there is electric current passing through the high-temperature resistance wire, the heat generated is transferred to the metal tube by crystalline magnesia powder. The surface diffuses and then transfers to the heated parts or air to achieve the purpose of heating.
