Is there a difference between electric heating tube and electric heating wire?

The electric heating tube and the electric heating wire are closely related. 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 generally be used in various electric heating environments, liquids and gases. Because the inner heating wire and the tube wall are tightly filled with magnesium oxide powder, the surface of the electric heating tube is non-conductive.

The heating wire is generally used in a closed space, because the surface is charged when it is heated by electricity.

For electric heating tube, electric heating wire and the difference between the two, electric heating tube is safer in comparison, but the cost of electric heating wire is lower, so both have their own advantages and disadvantages.
