Why is the life of the metal tubular electric heating tube long?

Due to the advantages of its own structure, the life of the metal tubular electric heating tube is much longer than that of other types of heating tubes. Why is the life of the metal tubular electric heating tube long?

The metal tubular heating tube has a spiral heating wire inside. The spiral heating wire is surrounded by dense insulating and heat-conducting filler and isolated from the outside world. Moreover, the metal tubular heating tube port has a sealing material, so the spiral heating wire is not It is easy to be oxidized and has a very long life span. Under reasonable design, manufacture, and use, its life span can be more than 10 years.

Of course, it is worth noting that the above-mentioned life span of more than 10 years refers to the reasonable design and the life span of the internal heating wire. However, in actual situations, most of the heating tubes are broken, not because the heating wire is broken, but the insulation layer is damaged, or the outer shell is damaged, causing the entire heating tube to fail to work normally.

Therefore, if you want the electric heating tube to have a long life, we must choose the shell material, insulating filler, and heating wire suitable for the electric heating tube according to the actual working environment, heating medium, working temperature, and use mode, so that they can cooperate with each other and increase the electric heating. Tube life, of course, the internal structure of each factory's design is also very important, which is like cooking, the same raw materials, different chefs make different tastes.

Of course, the prices of the metal tubular electric heating tube are also diverse, and cannot be generalized. Buyers who need to purchase electric heating tubes need to distinguish their choices.
