The first single tube is introduced: evenly distributed high temperature resistance wire in high temperature stainless steel tube of the stainless steel heating pipe, the gap part of dense fill in the thermal conductivity and crystallization of magnesium oxide powder properties have good insulation, this structure is not only the advanced heater, high thermal efficiency, and uniform heating, high temperature resistance wire when a current is passed in and the heat generated by the heater tube surface diffusion to the metal through the crystal magnesia powder, and then pass to the heated part or the air to achieve the purpose of heating.
Matters needing attention：
The electric heating part shall all be immersed in the heating medium, avoid heat does not exceed the allowable temperature of the heating and electric heating tube damage. In addition, the wiring lead out part should be exposed to the insulation layer of the heater or heater, so that this part should not be overheated and damaged.
The input power supply voltage should not exceed all kinds of electric heating tube marking the rated voltage of the 10%, such as suitable for lower than the rated voltage, heat generated by the electric heating pipes will fall.
3 electric terminal application 2 fastening nut relative in the wiring, not too hard to avoid lead screw loose and make the electric heat pipe damaged.
The electric heating tube terminal should keep clean and dry, otherwise can reduce the insulation performance and short circuit breakdown, if the application of chemical corrosion, inflammable and explosive liquid or gas in the environment, the electric heating tube wiring insulation sealing device in part to strict protection, to prevent accidents.
The heating some rayon and other substances, such as sodium nitrate, stearic acid, paraffin, beginning when heated should reduce the power supply voltage, electric heat pipe to reduce heat, when all melt and become a liquid, and then heated to the rated voltage.
The selection of the electric heating tube should pay special attention to the heating medium. Corrosion resistance of electric heating tube shell material.
The electric heating tube is used for a long time, if the tube surface scale and gathered thick grease should be removed regularly, otherwise it will make the electric heating tube heat transfer performance of the tube surface caused by decrease of heat load over rated to damage.
The electric heating pipe should be stored in dry warehouse, if the long-term placement, the surface moisture, in the use of the application zhaooubiao measuring insulation resistance. If less than 1 ohm /500 volts, the electric heating tube should be placed in the 200 degree drying box for drying.
The special electric heating tube should read the instructions in detail before the installation and use, so as not to damage.
