Solutions to uneven heating of electric heating tapes

The electric heating tape uses electric current to generate heat energy through a metal wire, thereby transferring the heat energy to the surface of the heating body, causing the surface temperature of the heating body to increase, and then transferring the heat to the heated object. However, in actual use, we will find that there are some problems with electric heating tapes. Uneven heating of electric heating tape is one of them.

Electric heating tape can be damaged for a number of reasons. How do we solve this problem? Here are some workarounds:

1、The electric heating tape gets damp, causing some electric heating tapes to short-circuit and fail to work properly. The solution is to repair or replace the damaged electric heating tape.

2. The uneven arrangement of the electric heating PTC resistance matrix elements or the damage of the resistance value will affect the heating effect of the electric heating. The solution is to replace the electric heating.

3. If the electric heating tape is pulled or cut improperly, the electric heating tape will not be able to achieve its original use effect, and a new heating tape needs to be replaced.

4. The voltage is too low and does not meet the required voltage, which will affect the heating power. The solution is to set up an independent power supply point for the electric heating system to ensure sufficient power supply voltage.

5. When selecting electric heating, you need to make a selection based on the high-temperature load-bearing value of the surface of the heating pipe and the actual area that requires heating to ensure that the electric heating tape can be heated evenly.

6. When installing electric heating, coiling should be carried out according to the ratio specified in the electric heating coiling calculation to ensure that the electric heating tape can be heated evenly.

7. When installing the external insulation layer, attention should be paid to the selection of insulation materials and the control of installation quality to ensure that the insulation layer can dissipate heat evenly.

In summary, in order to solve the problem of uneven heating of electric heating tapes, the above measures can be taken to ensure the use effect and extend the service life of electric heating tapes.
