Explosion-proof heaters are the surface disposal of electric heating tubes, and different electric heating tubes are in different environments, and the surface disposal methods of electric heating tubes are also different. Let’s take a look at different situations in order to prevent What kind of chemical treatment is needed for the rust of the electric heating tube?
The explosion-proof electric heater electric heating tube for water heating can also be divided into large electric heating tube for boiler application and small electric heating tube made by oneself according to its application place. Now, in order to prevent rust, the most common thing I usually do is to coat the surface of the electric heating tube with copper, of course, some aluminum plating.
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.
Among the factors that affect the quality of the electric heating tube in the explosion-proof heater, the quality of the material accounts for a very important reason. Reasonably choose the raw materials of the electric heating tube, in order to ensure the prerequisite of the quality of the electric heating tube in the explosion-proof heater. The principle of pipe selection: temperature resistance and corrosion resistance.
For low temperature tubes, BUNDY aluminum tubes and copper tubes are generally used, and high temperature tubes are generally stainless steel tubes and Ingle tubes. The Ingle 800 electric heating tube can be used in poor water quality conditions, and the Ingle 840 electric heating tube can have good oxidation resistance and good corrosion resistance under high temperature working conditions.
