1. Regularly remove the pipe scale accumulated on the surface of the heating pipe, otherwise the heat transfer performance of the heating pipe will be reduced and the heat load on the pipe surface will exceed the rated allowable and be damaged.
2 . The heating part of the heating pipe shall be fully immersed in the heating medium to prevent the heating pipe from being reported due to the unpleasant heat dissipation exceeding the allowable heating temperature. In addition, the outgoing part of the wiring shall be exposed to the insulation layer of the heater or outside the heater, so that this part shall not be damaged by overheating.
3 . The terminal of heating pipe shall be kept clean and dry. Otherwise, it will be broken down by short circuit due to reduced insulation performance. When it is used in the environment of chemical corrosion, flammable, explosive and other liquids or gases The wiring part of the heating pipe shall be strictly protected with insulating sealing device to prevent accidents.
4 . When heating certain substances such as viscose Such as sodium nitrate, stearic acid, stone wax, etc The power supply voltage should be reduced at the beginning of heating to reduce the heating of the heating pipe. When it is completely melted into liquid Then rise to the rated voltage for heating.
5 . The input is also a source, and the voltage should not exceed that in various 1% of the rated voltage of the tube, If it is suitable for low rated voltage, the thermal crystal generated by the head tube will also drop by degrees
6 . The special heating pipe shall read the relevant instructions carefully before installation and use to avoid damage
7 . The heating pipe terminal shall be relatively fastened with two nuts during wiring, and do not use too much force to avoid loosening the lead screw and damaging the heating pipe.
8 . Special attention shall be paid to the heating medium when selecting the heating pipe. The heating shell material shall be free from erosion.
9 . The heating pipe shall be stored in a dry warehouse. If the surface is affected by moisture due to long-term storage, a megger shall be used to measure the insulation group. If it is less than 1 megohm / 500 V, the heating pipe shall be dried in a 200 degree drying oven
