Because of its advantages of high thermal efficiency and no pollution, electric heating tubes are deeply loved by consumers. So what is the material of the electric heating tube? Let's take a look at the knowledge now.
First, what is the material of the electric heating tube
The shell of the electric heating tube is mainly made of metal tube, and then along the center of the tube axial spiral electric heating alloy wire, its gap filling compacted, and the use of insulating thermal conductivity of magnesia sand, the two ends of the pipe mouth and then silicone for sealing work, such metal armored electric heating element can not only heat air, but also can be used for metal molds and various liquids.
Second, what are the types of electric heating tubes
1. Stainless steel electric heating tube
There are many types of stainless steel materials for electric heating pipes, such as stainless steel 304, 321, 316L, etc. Heating tubes in normal environments, common stainless steel 304 and 321, but the higher the grade, the price is relatively expensive.
2. Teflon electric heating tube
Teflon electric heating tube is also called Flon electric heating tube, commonly known as tetrafluorine tube. The use environment is often used in corrosive liquids such as strong acids and alkalis, and the temperature is less than 105 °C, which has the advantage of non-adhesion and non-scaling, but relatively speaking, the price is very high.
3. Titanium electric heating tube
Titanium electric heating tubes are often used in passivation, chrome plating, copper acid, oxidation tank, chromic acid anodizing and other processes, so the price of titanium electric heating tubes is relatively high.
4. Quartz electric heating tube
Quartz electric heating tubes are often used to protect against corrosive liquids, but in addition to hydrofluoric acid. The main feature of quartz electric heating tube is that there is no need to use far-infrared coating, and the spectral radiation matching, the absorption characteristics are very good, but in long-term use, the radiation performance will not degenerate, and the conversion efficiency is high. After testing, it can save about 30% energy than general heating elements.
