High Grade Temperature Industrial Swaged-in Cartridge Heater

High Grade Temperature Industrial Swaged-in Cartridge Heater

The Cartridge Heater is also called a single-ended electric heating tube and a Cartridge Heaters. It is a kind of electric heating tube (tubular electric heating element). In the Chinese electric heating industry, there is a long-term model: M3. In the late 1990s, due to the wide application of electric heating tubes in China, the shape of electric heating tubes is also very large. In southern China, the electric heating tubes for such a outlet mold are called single-head electric heating tubes or single-ended electric heating tubes, which are very similar. of.
It is also called the cartridge heater in foreign countries. It is also called the image. Because the cartridge shell is cylindrical and one is blocked, it is a coincidence with China that it is called a single-head electric heating tube.

The typical structure of the Cartridge Heater (the most popular structure) is the same as that of the electric heating tube. It 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 electric heating wire and the lead-out wire are located in the center of the metal sheathed pipe. 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%.
