What are the shortcomings of stainless steel heating tubes
Compared with other heating methods, because there are metal pipes on the outside, the heating method that is relatively direct heating will affect a certain amount of heat loss and heat conduction. However, with the continuous progress of electric heating tube technology, the thermal efficiency of electric heating tube is also increasing. High, the impact of this aspect is getting smaller and smaller;
Compared with other metal pipes such as resistance heating and infrared heating, the electric heating tube has the disadvantage of high cost, but relatively speaking, it has the advantages of being safe, not easy to be damaged during installation and transportation, and long life. Compared with other heating methods (such as induction heating, arc heating, fuel heating), it has the advantages of small initial investment, small footprint, and less restriction;
The stainless steel electric heating tube is prone to scale when heating water. When the electric heating tube is working, the temperature of the external tube can reach 90-120*C. Generally speaking, calcium and magnesium ions in the water will begin to precipitate and form at 60"C. Scale. The formation of scale will cause many problems. The formation of scale will affect water quality, so it will affect people's quality of life when used for domestic water; in addition, after the formation of scale on the surface of the heating pipe, it will cause uneven heating. Causes cavitation, causes tube body breakdown, makes heating tube burn out. However, the impact of this aspect can be solved well after the use of high-performance tubes. In some areas with poor water quality, it can be used for 800 stainless steel materials. Can solve the scale problem well, not only can reduce the scale, but also increase the service life of the heating tube, and reduce the repair rate.
As the country pays more and more attention to environmental protection, the use of electric heating tubes for electric energy has unmatched energy-saving and environmental protection advantages. In terms of convenience, heating tubes can be conveniently used only by having power supply. Its control and use It is very simple, and secondly, the application range of electric heating is very wide, with very small restrictions and high safety factor. Based on the above points, the development of the stainless steel electric heating tube industry has a good prospect. In the future, whether in industry or civilian use, heating tubes will be widely promoted to contribute to the quality of human life and environmental protection and energy saving.
