Nowadays, electric heating tubes play an indispensable role in our daily life. We also pay more and more attention to the safe use of electric heating tubes. Once we do not strictly abide by the precautions for the safe use of electric heating tubes, it will simply induce some safety accidents and damage our personal safety. How to use electric heating tube safely?

        1. The electric heating pipe shall operate under the following conditions: a. the relative humidity of the air shall not be greater than 95%, and there shall be no explosive and corrosive gases. B. The operating voltage shall not be greater than 1.1 times the additional value, and the shell shall be grounded. C. Insulation resistance ≥ 1m Ω, dielectric strength: 2KV / 1min. If the operating environment does not meet the above requirements, please stop using the electric heating tube.

        2. The electric heating pipe shall be positioned and fixed, and the useful heating area must be immersed in liquid or metal solid, and empty burning is prohibited. If scale or carbon deposit is found on the surface of the pipe body, it shall be removed and reused in time to avoid affecting the heat dissipation and shortening the service life.

        3. When heating fusible metal or solid nitrate, alkali, asphalt, paraffin, etc., the application voltage shall be reduced first, and the additional voltage can be increased only after the medium is melted.

        4. When heating air, the elements shall be placed evenly and crosswise, so that the electric heating tube has excellent heat dissipation conditions and the flowing air can be fully heated.

        5. Safety measures should be considered when heating nitrate to avoid explosion accidents.

        6. Some wiring shall be placed outside the insulation layer to avoid touching with corrosive and explosive media and water; The lead wire shall be able to accept the temperature and heating load of some wiring for a long time. Excessive force shall be avoided when tightening the wiring screw.

        7. The electric heating tube shall be stored in a dry place. If the insulation resistance is lower than 1m Ω for a long time, it can be dried in an oven at the mercy of 200 ℃, or the voltage can be reduced and heated until the insulation resistance is recovered.

        8. The magnesia powder at the outlet end of the electric heating pipe shall avoid the entry of pollutants and moisture in the application place and the occurrence of electric leakage accidents.
