The structure of the cartridge electric heating tube is to put an electric heating wire in the metal tube, and tightly fill the gap part with a high-temperature magnesium oxide rod with good thermal conductivity and insulation. The two ends of the electric heating wire are connected to the power supply through two lead rods. Pick up. It has the advantages of simple structure, long life, high thermal efficiency, good mechanical strength, can be bent into various shapes, safe to use, temperature resistance, corrosion resistance, etc.; for low temperature tubes, aluminum tubes, copper tubes, and high temperature tubes are generally used. It adopts stainless steel tube and Ingle tube. The Ingle 800 electric heating tube can be used in poor water quality conditions, and the Ingle 840 electric heating tube can have good oxidation resistance and good corrosion resistance under high temperature working conditions.

The cartridge electric heating tube is suitable for working in heating media that cannot be wired at both ends, such as high and low temperature insertion heating of various large and small molds and mechanical equipment, including punching dies and other molds, medical equipment, plastic sealing machines, bottle closures Cover machine, continuous automatic sealing machine, cigarette making machine, etc. The main ones are as follows:  

1. In medical and sanitary disinfection equipment, such as sterilizers, sterilizers, etc. 

2. Heating of motor vacuum dipping equipment, enameled wire drying device, etc.

3. Various household electric heating appliances in daily life, such as electric stoves, electric ovens, rice cookers, electric frying pans, electric frying pans, water heaters, electric irons and other products.

4. Used to dry wood, paper, printing and dyeing, paint waste, etc. 

5. Melting and heating of saltpeter and other salt substances.

6. Melting low melting point alloys, such as lead melting furnace, tin melting furnace, etc. 

7. Building heating.

8. Infrared radiation heating device. 

9. Low-temperature electric furnaces such as industrial electric furnaces and electric furnace boxes with air circulation.

10. Heating device in oil, water and other chemical liquids and electroplating baths. 

11. Sea water electric distillation device.

12. Heating device for alkali and acid.

13. In the food industry, it is used to bake various breads, biscuits and pastries, and used as an electric heating device in a water tunnel.

14. Various household electric heating appliances in daily life, such as electric stoves, electric ovens, rice cookers, electric frying pans, water heaters, electric irons and other products.

15. In medical and sanitary disinfection equipment, such as sterilizers, sterilizers, etc.
