Heating principle of industrial electric heating tube
The industrial electric heating pipe is to put the electric heating wire into the seamless metal pipe, such as carbon steel pipe, titanium pipe, copper pipe, stainless steel, etc., and then fill the gap of the pipe with magnesium oxide powder (magnesium powder cannot contain impurities, otherwise the electric heating pipe will be used for a long time. burst), and then shrink the pipe and process it into the desired shape. Magnesium oxide has good thermal conductivity and insulation, and can transfer heat well. Although the electric heating tube has a simple structure, its thermal efficiency and mechanical strength are very good. It can be used to heat various acids, bases, and salt liquids, and can also be used to melt some metals that can be melted at lower temperatures.
Composition and application of industrial electric heating pipes
The industrial electric heating tube is small in size, high in power, strong in temperature control, long in life, high in thermal efficiency, and almost 100% heat transfer. In the long-term use of industrial electric heating pipes, there will always be problems such as scaling and corrosion, so now they are equipped with auxiliary electric heating pipes, made of stainless steel, which can be taken out for cleaning, which improves the service life and safety of electric heating pipes. At the same time, the auxiliary heater is equipped with a thermostat, which can control the temperature well and prevent damage to components.
The core component of the industrial electric heating tube is the stainless steel electric heating tube. In order to ensure the quality, imported materials are generally used, advanced equipment and exquisite craftsmanship are used to achieve the best insulation, pressure resistance and moisture resistance. Make it safer and more reliable while playing the role of the industry. The electric heating tube is also equipped with a safety pressure valve for downward discharge, which can reduce the impact on the surrounding pipelines and avoid accidents during operation. Industrial electric heating tubes can be used to heat air, oil, water, chemical media, acids, alkalis, salts, low melting point metals, etc.
Leakage problems and treatment during heating
1. Check whether the grounding wire is connected correctly before use;
2. Check and repair the electric heating tube frequently. If it is damaged, it is best to replace the electric heating tube;
3. Correctly clean the heating tube, try not to touch it with water, and keep it dry;
4. Check working circuits and wires to eliminate the danger of leakage.
Classification of industrial electric heating pipes
1. According to the heating method: conventional resistance heating tube, radiant electric heating tube;
2. According to the shape: straight, U-shaped, L-shaped, W-shaped, fin-shaped, special-shaped, etc.;
3. According to the outlet method: single head electric heating tube, double head electric heating tube;
4. According to usage: dry burning electric heating tube, water burning electric heating tube.
