Electric heating tubes for water heating can also be divided into large electric heating tubes for boiler applications and small electric heating tubes made by individuals according to their application. In order to prevent rust, many electric heating tubes have adopted a lot of chemical treatment. Generally, it is common for us to carry out copper crossing treatment on the surface of the electric heating tube. Of course there is also aluminum.
Cast aluminum heaters are mainly divided into: cast aluminum heating ring with air groove, air-cooled cast aluminum heating ring, cast aluminum heater for medical equipment, round cake type cast aluminum heating plate, plug type cast aluminum heating plate, right angle cast aluminum Heating plate, extruder cast aluminum heater, water-cooled cast aluminum heater, cast aluminum electric heating ring with duct, cast aluminum heating ring for injection molding machine, supply cast aluminum heating ring for foaming machine, etc. Cast copper heaters are mainly divided into: cast copper heating plate, pelletizer cast copper electric heating plate, drum-type cast copper heater, C-type cast copper heater, right-angle pelletizer cast copper heating plate, etc.
In the production process of a good electric heating tube, it has to go through many processes. Its purpose is for the life and safety of the electric heating tube.
The surface of the electric heating tube needs to be chemically treated in order to prevent rust, that is, the surface treatment of the electric heating tube. But not all heating tubes need to be treated the same. This depends on the environment and how it is used. The materials of the electric heating tubes produced in different working environments are also different. But the function of the electric heating tube, that is, the function of the electric heating tube, is the same. The basic function of the electric heating tube is external heating.
