Reasons for the Long Life of Metal Tubular Electric Heating Tubes

- May 12, 2020-

Due to the superiority of the metal tubular electric heating tube, its life is much longer than that of other types of heating tubes, so why does the metal tubular electric heating tube have such a long life?

 

The inner heating wire of the metal tubular electric heating tube is spiral. The spiral heating wire is surrounded by dense insulating and thermally conductive filler and is isolated from the outer. Moreover, the metal tubular electric heating tube has a sealing material, so the spiral electric heating wire is not easy to oxidize and has a very long life. Its life can be more than 10 years accprding to reasonable design, manufacture and use.
