The stainless steel heating tube has better heat resistance and is resistant to dry burning. The technology is relatively mature and the cost is relatively low. What are the advantages of stainless steel heating tubes? Let's take a look.
First of all, the outside of the stainless steel heating pipe is a metal pipe (which can withstand dry burning, can be heated in water, and can be resistant to corrosion), 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 the relative resistance heating has the characteristics of insulation and safety of use;
Third, the stainless steel electric heating tube has a high degree of controllability, can be controlled by different wiring methods and power regulation, and can have a high degree of automation 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 the power supply control needs to be connected to open and close, so the stainless steel electric hair The promotion of heat pipes has been widely recognized.
The difference between the quality of the stainless steel electric heating tube is mainly due to the different nickel content. Nickel is an excellent corrosion-resistant material. When it is combined with chromium in stainless steel, the corrosion resistance and process performance of the stainless steel are improved. However, for low-carbon nickel steel to obtain a pure austenitic structure, the nickel content should be 24%, and only when the nickel content is 27%, the corrosion resistance of the steel in some media is significantly changed.
Therefore, from the material point of view, 800, 840, 316L is relatively good corrosion-resistant and high-temperature resistant stainless steel electric heating tube, 800 stainless steel tube contains 30% nickel, 840 tube nickel content reaches 20%, but if it is poor Some contain only 8% nickel. Therefore, the use of high-temperature resistant high temperature corrosion resistant stainless steel heating tubes is also very advantageous.
