What is the difference between stainless steel heating tube and electric heating wire？
Regarding the electric heating tube and the electric heating wire, many people don't understand it constantly. Both are used for heating, but the difference between them must be clarified before use. When it is actually used for air heating, both can be used the same, so what is the detailed difference between them? Next, I will give you a detailed introduction.
The so-called electric heating tube is to make the heating wire into a spring shape according to the requested resistance, and then place it in the center of the tube. Then the gap between the heating wire and the tube wall is filled with magnesium oxide powder with very good insulation. Then use silica gel to seal, so that the electric heating tube is made. Because it is cheap, easy to use, and pollution-free, it is widely used in many places.
Electric heating wires are more common than iron-chromium-aluminum and nickel-chromium electric heating alloys. They all have strong oxidation resistance. Although the oxidation resistance treatment is stopped before leaving the factory, there will be certain component damage in transportation, equipment, etc. Therefore, the pre-oxidation treatment must be stopped before use. Its service life is largely related to the diameter and thickness of the heating wire. It is mostly used in industrial heating equipment and civil heating appliances such as medical, chemical, electronic, glass and so on. The heating tube and the heating wire are closely related. The heating wire can be said to be the original material of the heating tube, so its cost is lower. However, the electric heating tube can be used in various electric heating environments, liquids, and gases under normal conditions. Because the internal heating wire and the tube wall are tightly filled with magnesium oxide powder, the appearance of the electric heating tube is not conductive. Electric heating wires are generally used in enclosed spaces, because their appearance is charged when they are energized and heated.
