Product Desription 

Electric heating pipe, also known as heating pipe, heating pipe, scientific name tubular electric heater component, is a coiled heating wire (resistance wire) placed in a metal pipe,

Insulating powder (MgO) having good heat resistance, thermal conductivity, and insulation is filled in the periphery and the gap portion, and the lead wire or the lead wire is taken out at both ends of the heating wire. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Widely used in a variety of saltpet tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot stamping and other devices.

The electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various heating occasions.


Small size and high power: The heater is mainly a clustered tubular electric heating element. The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. High heating temperature: The heater is designed for a maximum mission temperature of 850 °C. The medium outlet temperature is average and the temperature control accuracy is high. Wide use and strong compliance: The heater can be used in explosion-proof or popular places. The explosion-proof grade can reach dIIB and C, and the pressure can reach 20MPa. Long life and high reliability: The heater is made of extraordinary electric heating data, with low design power load and multiple maintenance, which greatly increases the safety and life of the electric heater. Fully active control: According to the requirements, the heater circuit design can conveniently complete the active temperature control of the outlet temperature, flow, pressure and other parameters, and can be networked with the computer. The energy saving result is obvious, and almost 100% of the heat generated by the electric energy is transmitted to the heating medium.




The typical structure of a metal tubular electric heating tube (the most popular structure) is generally composed of five parts: an insulator, a sealing material, an extraction rod, a filler, a heating wire, a metal sheathed tube, and a terminal.

The spiral heating wire and the extraction rod are located in the center of the metal sheath tube. The manufacturing process is to insert the spiral electric heating wire into the seamless steel pipe, the copper pipe or the aluminum pipe, and the gap is evenly filled with the insulation by the multi-tube filling machine. A thermally conductive oxidizing medium such as crystalline magnesium oxide powder (also available in alumina or clean quartz sand). Then, the tube diameter is reduced by a tube shrinking machine to make the oxide medium dense (density reaches 3.3 g/cm3 or more), and the heating wire is insulated from the air, and the center position does not shift and touches the tube wall. such. The calorific value per unit area can be increased by a factor of ten. The service life can also be increased to more than 10 years. Compared with the same large heat electric heating element, the tubular electric heating tube can save 5% of the electrothermal material, and the thermal efficiency can reach more than 90%.

Therefore, from the structure of the electric heating tube, the metal tubular electric heating tube is the most widely used, sealed structure electric heating element with simple structure, reliable performance and long service life, which can be successfully applied to industrial and household appliances, and is increasingly used. widely. I hope more users have a clear understanding of the structural principle of the electric heating tube.
