Common problems and precautions when using a single head heating tube

Before installing the application, the dedicated heating tube should read relevant articles in detail to understand the basic parameters and prevent damage.

2. The hot part of the single head heating tube should penetrate into the heating material to prevent slow heating release, exceeding the allowed heating temperature, and damaging the heating tube. In addition, a part of the wiring should be exposed to the insulation layer of the electric heater or outside the electric heater to avoid overheating and damage.

When inputting a switching power supply, the working voltage shall not exceed 10% of the rated current marked on various heating tubes. If applied below the rated current, the heat generated by a single head heating tube will also be reduced.

4. The outlet end of a single head heating tube should be kept clean and dry. On the contrary, it will reduce the dielectric strength and be penetrated by short circuit faults. If using natural environments with liquids or gases that are chemically corrosive, flammable, flammable, or explosive, insulation layer sealing equipment should be used to strictly protect the outgoing part of the heating tube to prevent safety accidents.

5. Heat some adhesives and other chemicals, such as sodium nitrate. Polyether. Paraffin wax, etc., Reduce the power supply voltage at the beginning of heating to lower the heating value of the heating tube, and then increase it to the rated current for heating.

6. When using a single head heating tube, attention should be paid to the heating material. Solve the problem of no deposition of heating tube shell raw materials.

7. Single head electric heating tubes should be stored in a dry warehouse. If due to long-term placement and surface moisture regain, a megohmmeter should be used to clearly measure the starting ground resistance. If it is below 1 megaohm/500 volts, the heating tube should be placed in a 200 degree drying oven for air drying.

8. The single head heating tube has a long application time. If scale and oil stains accumulate on the surface, they should be eliminated in a timely manner, otherwise the thermal conductivity of the heating pipe will decrease, resulting in heat consumption on the surface of the pipeline exceeding the rated value.
