A single headed tube is made by placing an electric heating element into a metal tube and tightly filling the gaps with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation properties, which is processed by other processes. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. Widely applicable to various saltpeter tanks, water tanks, oil tanks, acid-base tanks, melting furnaces for fusible metals, air heating furnaces, drying furnaces, drying boxes, hot pressing molds and other devices.
Single head tube is an electrical component that specifically converts electrical energy into heat energy. Due to its low price, convenient use, easy installation, and pollution-free nature, it is widely used in various heating situations. Currently, there are many manufacturers of electric heating elements, and there are also many brands of electric heating tubes, including famous ones such as Shanglong brand and Changlong brand. The service life of electric heating tubes is very long, with a general design service life of over 10000 hours, especially for heating elements, Can have a lifespan of 5 heating seasons.
The origin of single headed pipes
The single headed tube in China's electric heating industry has a long known model: M3. In the late 1990s, due to the widespread use of electric heating tubes in China, the shapes of electric heating tubes also became many. In southern China, this type of electric heating tube used for molds with one end output is called a single end tube, which looks very similar.
In foreign countries, it is called a cartridge heater, which is also a figurative term because the shell of the cartridge is cylindrical and one end is also blocked, which is similar to the saying in China that a single head tube is a clever and identical work.
