1. The gap inside the electric heating pipe in the baking room is filled with magnesium oxide sand. The magnesium oxide sand at the outlet of the finned electric heating pipe is prone to contamination due to the infiltration of impurities and moisture. Therefore, it is necessary to pay attention to the state of the outlet of the finned electric heating pipe during operation to avoid leakage accidents caused by this.

2. When using finned electric heating tubes for heating liquids or metal solids, it is important to ensure that the tubes are completely placed inside the heated object and do not allow empty burning. If there is scale or carbon on the outer metal shell of the finned electric heating tube after use, it should be promptly removed to avoid affecting the heat dissipation performance and service life of the finned electric heating tube.

3. When using an oven electric heating tube for air heating, it is important to pay attention to the uniform arrangement of the finned electric heating tubes. The advantage of doing so is to ensure that the finned electric heating tubes have sufficient and uniform heat dissipation space, and to ensure air flow as much as possible, thereby improving the heating efficiency of the finned electric heating tubes.

4. The storage location of finned electric heating tubes must be kept dry and with appropriate insulation resistance. If the insulation resistance of the storage environment of finned electric heating tubes is found to be too low during use, they can be restored at low voltage before use. Finned electric heating tubes should be properly fixed before use, and the wiring should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and water.

5. When the oven electric heating tube is used to heat easily melted metals or solid substances such as nitrates, paraffin, asphalt, etc., the heating substance needs to be melted first. At this time, the external voltage of the finned electric heating tube can be reduced, and after the melting is completed, it can be restored to the rated voltage. In addition, when heating substances such as nitrate that are prone to explosion accidents with finned electric heating tubes, safety measures should be fully considered.
