1, the electric heat pipe should be positioned and fixed, the effective heating area must be immersed in liquid or metal solid, air burning is strictly prohibited. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned and reused in time to avoid affecting the heat dissipation and shortening the service life。

2, heating fusible metal or solid salt, alkali, asphalt, paraffin, etc., should first reduce the use of voltage, until the medium melts, in order to rise to the rated voltage.
3. Magnesium oxide powder at the outlet end of the electric heat pipe should be avoided by pollutants and water infiltration in the use place to prevent the occurrence of leakage accidents.
4, heating the air elements should be crossed evenly arranged, so that the elements have good heat dissipation conditions, the flow of air can be fully heated.
5. Safety measures should be considered when heating nitrate to prevent explosion accidents.
6, the wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, moisture; The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time, and the wiring screw should be tightened to avoid excessive force.
7, the component should be stored in a dry place, if the insulation resistance is less than 1MΩ for a long time, it can be dried in the oven at about 200 ° C, or reduce the voltage and power heating until the insulation resistance is restored.
