Is there a difference between stainless steel electric heating tubes and electric heating wires?

- Jul 15, 2019-

For electric heating tubes and electric heating wires, many people have not understood that both are used for heating, but it is necessary to find out the difference between them before use. In fact, when used for air heating, both can be used the same, so what is the difference between them? Next, we will introduce you in detail.


First, it is an electric heating tube.


The so-called electric heating tube is that the heating wire is made into a spring shape according to the required resistance, and then placed in the center of the tube, and then the gap between the heating wire and the tube wall is filled with magnesium oxide powder with excellent insulation. Then use silicone to seal, so that the electric heating tube is made. Because it is cheap, easy to use, and non-polluting, it is widely used in many occasions.


Second, it is the heating wire


Iron wire chrome aluminum and nickel chrome electrothermal alloy are common in electric heating wire. They all have strong oxidation resistance. Although they are treated with anti-oxidation treatment before leaving the factory, they do not rule out certain component damage during transportation and installation. Therefore, it must be pre-oxidized before use. Its service life is largely related to the diameter and thickness of the heating wire, and it is mostly used in industrial heating equipment such as medical, chemical, electronics, glass, and civil heating appliances.


The difference between electric heating tube and electric heating wire


The electric heating tube is closely related to the electric heating wire. The electric heating wire can be said to be the raw material of the electric heating tube, so its cost is lower. However, the electric heating tube can be generally used in various electric heating environments, liquids, and gases, because the internal heating wire and the tube wall are closely filled with magnesium oxide powder, so the surface of the electric heating tube is not electrically conductive. The heating wire is generally used in a closed space because it is electrically charged when heated.
