Precautions for Using Flange Electric Heating Tubes

Dari Electric recommends for you

Many netizens have reported online that flange electric heating tubes often experience leakage or shortened service life when used alone. We remind customers that such problems may be due to choosing unqualified products on one hand, and on the other hand, the following points should be noted during use:

   1. When flange electric heating tubes are used to heat easily melted metals or solid nitrates, paraffin, asphalt, etc., the material to be heated must be melted first. At this time, the external voltage of the flange electric heating tube can be reduced, and after melting is completed, restore to the rated voltage. In addition, when heating substances like nitrates that are prone to explosion accidents, safety measures should be fully considered.

   2. The storage location of flange electric heating tubes must be kept dry and with appropriate insulation resistance. If it is found that the insulation resistance of the storage environment is too low during use, it can be restored by applying low voltage power before use. Before use, the flange electric heating tube should be properly fixed, and the wiring part should be placed outside the insulation layer, avoiding contact with corrosive, explosive media and water.

   3. When flange electric heating tubes are used for air heating, attention should be paid to the uniform arrangement of the tubes. The benefit of this is to ensure sufficient and uniform heat dissipation space, and to ensure air fluidity as much as possible, improving the heating efficiency of the flange electric heating tubes.

   4. The internal gap of the flange electric heating tube is filled with magnesium oxide sand. The magnesium oxide sand at the outlet end of the flange electric heating tube is easily contaminated by impurities and moisture, so attention should be paid to the state of the outlet end during operation to avoid leakage accidents caused by this.
