The stainless steel heating tube has better heat resistance, dry burning resistance, mature technology, and lower cost. What are the advantages of stainless steel heating tubes? Let's take a look.
First of all, the exterior of the stainless steel heating tube is a metal tube (which can withstand dry burning, can heat up in water, and can be corrosion resistant), which can adapt to more external use environments and has a wide range of applications;
Secondly, the inside of the stainless steel heating tube is filled with high-temperature insulating magnesium oxide powder, so it has the characteristics of insulation and safe use relative to resistance heating;
Third, the stainless steel electric heating tube has a high degree of controllability, and can be controlled and used by different wiring methods and power regulation, and can have a high degree of automatic control;

Finally, 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 need to connect the power supply to control the opening and closing, so the stainless steel electric heating tube The promotion of heat pipes has been widely recognized.
The difference between the quality of the stainless steel electric heating tube is mainly the nickel content. Nickel is an excellent corrosion-resistant material. After the stainless steel is combined with chromium, the corrosion resistance and process performance of the stainless steel can be improved to some extent. However, for low-carbon nickel steel to obtain a pure austenitic structure, the nickel content must reach 24%, and only when the nickel content is 27% can the corrosion resistance of the steel in certain media be significantly changed.
Therefore, in terms of materials, 800, 840, and 316L are relatively good corrosion-resistant and high-temperature resistant stainless steel electric heating tubes. The 800 stainless steel tube contains 30% nickel and the 840 tube contains 20% nickel. Some have only 8% nickel. Therefore, the use of high temperature and corrosion resistant stainless steel heating tubes with high nickel content is also very advantageous.
