How to prevent rust in small and medium-sized electric heating element of explosion-proof heaters?
The explosion-proof heater is the surface treatment of electric tubular heater, and the environment of different electric heating pipes is different. The method of surface treatment of electric tubular heateris also different. Let's take a look at the different situations in order to prevent electric heating in the explosion-proof heater What chemical treatments are required for rusting of the tube.
According to the place where it is applied, the electric tubular heater of the explosion-proof electric heater for water heating can also be divided into a large electric tubular heater for a boiler application and a small tubular heater made by an individual. Now to prevent rust, the most common thing I usually do is copper plating on the surface of the electric tubular heater. Of course, there are some aluminum plating.
Cast aluminum heaters are mainly divided into: cast aluminum heating coils with air grooves, air-cooled cast aluminum heating coils, cast aluminum heaters for medical equipment, round-shaped cast aluminum heating plates, plug-type cast aluminum heating plates, and right-angle cast aluminum Heating plate, extruder cast aluminum heater, water-cooled cast aluminum heater, air groove cast aluminum heating coil, injection molding machine cast aluminum heating coil, foaming machine cast aluminum heating coil, etc. The cast copper heater is mainly divided into: cast copper heating plate, granulator cast copper electric heating plate, drum type cast copper heater, C-type cast copper heater, right-angle type pelletizer cast copper heating plate and so on.
Among the factors that affect the quality of electric tubular heaters in explosion-proof heaters, the quality of materials accounts for a very important reason. Reasonable selection of raw materials for electric tubular heaters, in order to ensure the premise of the quality of electric tubular heater in explosion-proof heaters. Selection principles of pipes: temperature and corrosion resistance.
For low-temperature pipes, BUNDY aluminum pipes and copper pipes are generally used, and high-temperature pipes are generally stainless steel pipes and Ingle pipes. Ingle's 800 electric tubular heatercan be used under poor water quality. Ingle's 840 electric tubular heater can have good oxidation resistance and good corrosion resistance under high temperature working conditions.
