1. The electric heating tube should be well positioned and fixed. The effective heating area must be completely immersed in liquid or metal solids. When scale or carbon is found on the surface of the pipe body, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life.
2. When heating fusible metal or solid nitrate, alkali, bitumen, paraffin, etc., the operating voltage should be reduced first, and the medium can be raised to the rated voltage only after the medium is melted.
3. Magnesium oxide powder at the outlet end of the electric heating pipe should be protected from the infiltration of pollutants and moisture at the place of use to prevent leakage accidents.
4. When heating the air, the components should be arranged uniformly across, so that the components have good heat dissipation conditions, so that the flowing air can be fully heated.
5. Safety measures should be considered when heating nitrate to prevent explosion accidents.
6. The connection part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture; the lead wire should be able to withstand the temperature and heating load of the connection part for a long time, and avoid excessive force when tightening the connection screw.
7. The component should be stored in a dry place. If the insulation resistance is lower than 1MΩ for a long time, it can be dried in an oven at about 200 ° C or reduced in voltage and heated until the insulation resistance is restored.
