For achieving the above object, the utility model provides a kind of flange form heater, comprise metal outer pipe (1), heating wire (2), magnesium oxide crystalline solid (3), electric heating draws rod (4), insulating trip (5) and sealing compound (7), in metal outer pipe, be also provided with the insulated tube identical with its shape, described heating wire (2) is spirally wrapped around on the outer wall of insulated tube; Described metal outer pipe (1) is made up of titanium alloy, and the outside wall surface of described metal outer pipe (1) is also coated with high density polyethylene coating.
Above-mentioned flange form heater, wherein, described metal outer pipe is U-shaped structure, and be made up of two straight tubes (11) and the bend pipe (12) that connects corresponding thereto, the pipe thickness of described bend pipe (12) is greater than the pipe thickness of described straight tube (11).
Above-mentioned flange form heater, wherein, the pipe thickness of described bend pipe (12) is 1.5 ~ 2 times of straight tube (11) pipe thickness.
Above-mentioned flange form heater, wherein, one end that described electric heating draws rod (4) extends to outside it by the inside of described straight tube (11), rod (41) is drawn to be formed outside electric heating, the part being placed in described straight tube (11) draws rod (42) to be formed in electric heating, and the outside wall surface of drawing rod (42) in described electric heating is coated with insulating barrier (422).
Above-mentioned flange form heater, wherein, sealing compound (7) is also injected with at the mouth of pipe place of described straight tube (11), described sealing compound (7) outer face is also coated with insulating trip (5), draws rod (41) outside described electric heating successively through the inside of described sealing compound (7) and described insulating trip (5).
Above-mentioned flange form heater, wherein, draws on rod (41) and is also arranged with hold-down nut (6) outside described electric heating.
Compared with prior art, the utility model has the following advantages:
The utility model by by heating wire winding at the insulated tube identical with metal outer pipe shape, the intensity of heating wire in metal outer pipe can be strengthened;
Because metal outer pipe is made up of titanium alloy, and be also coated with high density polyethylene coating in the outside wall surface of metal outer pipe, to make metal outer pipe, there is excellent corrosion resistant performance.

Embodiment
As shown in Figure 1, this flange form heater comprises metal outer pipe 1, heating wire 2, magnesium oxide crystalline solid 3, electric heating draws rod 4, insulating trip 5 and sealing compound 7.Metal outer pipe is U-shaped structure, and be made up of two straight tubes 11 and the bend pipe 12 that connects corresponding thereto, two straight tubes are all adopt welding manner to be connected with bend pipe.Be processed into by bending technique by bend pipe 12, in Forging Process, tube wall can be thinning, and can be subject to larger stress, in order to avoid bending part fracture, bend pipe 12 must be made to have larger radius.Therefore, the pipe thickness of bend pipe 12 is greater than the pipe thickness of straight tube 1, and as optimal case, the pipe thickness of bend pipe 12 is 1.5 ~ 2 times of straight tube 11 pipe thickness.
In addition, metal outer pipe is made up of titanium alloy, and the outside wall surface of metal outer pipe is also coated with high density polyethylene coating (not describing in figure).
In metal outer pipe 1, be provided with the insulated tube (in figure do not describe) identical with its shape, heating wire 2 is spirally wrapped around in the outside wall surface of insulated tube.
One end that electric heating draws rod 4 extends to outside it by the inside of straight tube 11, to draw rod 41 to be formed outside electric heating, and the part being placed in straight tube 11 draws rod 42 to be formed in electric heating, and the outside wall surface of drawing excellent 42 in electric heating is coated with insulating barrier 422.Draw rod 42 in one end electric heating of heating wire to be connected.Draw in electric heating rod outside wall surface on after being coated with insulating barrier, therefore, make in electric heating, to draw clavate and become not heating part.
Sealing compound 7 is also injected with at the mouth of pipe place of straight tube 11, sealing compound 7 outer face is also coated with insulating trip 5, rod 41 is drawn successively through inside with insulating trip 5 of sealing compound 7 outside electric heating, and a part of drawing rod 42 in electric heating is arranged in sealing compound 7, owing to drawing rod in electric heating for not heating part, therefore, sealing compound can not be made to melt under the effect of heat.
Draw in heating wire 2, metal outer pipe 1 and electric heating around rod 42 and be also filled with magnesium oxide crystalline solid 3.
Draw outside electric heating on rod 41 and be also arranged with hold-down nut 6.Flange can be arranged on outside electric heating draws on rod, the rear end face of flange is contacted with insulating trip, and is fixed flange by hold-down nut.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection range of the present utility model.
