The differences between stainless steel electric heating tubes and other heating methods

Firstly, the stainless steel heating tube is made of metal pipes on the outside (which can withstand dry burning, heating in water, and corrosion), which can adapt to more external usage environments and have a wide range of applications;

Secondly, the interior of the stainless steel heating tube is filled with high-temperature insulating magnesium oxide powder, so the relative resistance heating has the characteristics of insulation and safe use;

Thirdly, stainless steel electric heating tubes have a high degree of controllability and can be controlled using different wiring methods and power regulation, which can have a high degree of automation control;

The use of stainless steel electric heating tubes is very convenient and does not require high professional knowledge. In the use of some simple stainless steel electric heating tubes, only the power supply is connected to control the opening and closing, so it has been widely recognized in the promotion of stainless steel electric heating tubes.

What are the drawbacks of stainless steel heating pipes?

Firstly, compared to other heating methods, the relatively direct heating method with metal pipes on the outside will have some impact on heat loss and conduction. However, with the continuous progress of electric heating pipe technology, the thermal efficiency of electric heating pipes is also increasing, and the impact in this regard is also decreasing;

Secondly, compared to other methods such as resistance heating and infrared heating, heating tubes have the disadvantage of high cost due to the use of metal pipes. However, they have the advantages of safe use, less damage during installation and transportation, and longer service life. Moreover, compared to other heating methods such as induction heating, arc heating, and fuel heating, it has the advantages of small initial investment, small ground occupation, and fewer usage restrictions;

Thirdly, stainless steel electric heating pipes are prone to scale when heating water. When the electric heating pipe is in operation, the external pipe temperature can reach 90-120 ℃. Generally speaking, calcium and magnesium ions in the water will begin to precipitate at 60 ℃, forming scale. The formation of scale can cause many problems, and after scale formation, it can affect water quality, so it can affect people's quality of life when used in domestic water; Furthermore, after the formation of scale on the surface of the heating tube, uneven heating can easily lead to cavitation, causing breakdown of the tube body and causing the heating tube to burn out. However, this impact can also be well resolved after the use of high-performance pipes. In some areas with poor water quality, 800 stainless steel material can be used, which can effectively solve the problem of scale. It can not only reduce scale but also increase the service life of heating pipes and reduce repair rates.
