Glass Heating Pipe (ceramic type)


Glass heating pipe with electric heating film is developed for high temperature heating applications.

The mixed nonmetallic electric conducting materials (ceramic, glass´) are printed and sintered on the outer surface of glass pipes as electric heating film.

The heating film provides thermal by heat conduction & convection as heat transfer way.


Product Features:

-          Long service life because of no oxidation while working of the heating film

-          The liquid in the glass pipe flows separately from heating film, so there is no leakage of electricity

-          High heat conducting rate (97%)

-          Low temperature of the heating film (180-200 ≧), does not affect the service life of other parts

-          Good resistant under hot/cool impacting (put the glass pipe of 800 ≧ into liquid of 20 ≧ for 3 times, there is no break)


Typical applications:

-          Foot bath bucket

-          Electric heater for water bed

-          Instant water heater

-          Washing machine and dishwasher
