Temperature controlled anti dry burning electric boiler electric heating tube

Temperature controlled anti dry burning electric boiler electric heating tube

1, Small size and high heating power;

2, It can heat various media in various occasions, such as explosion-proof situations, etc;

3, The heating temperature can generally reach 720 ℃;

4, The heating system can be fully automated, including controlling the electric heating system through the DCS system;

5, Long service life, with multiple protection systems, safe and reliable.

Uniformly distribute high-temperature resistance wires inside high-temperature resistant stainless steel seamless pipes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced and has high thermal efficiency, but also generates uniform heat. When there is current passing through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesium oxide powder to the surface of the metal pipe, and then transfers to the heated part or air to achieve the purpose of heating.

The electric heating tube of an electric boiler is classified as a hazardous material during operation. Please remember this point, and its maintenance is also very important because the electric heating tube works with electricity and there is a certain potential danger. Therefore, the maintenance of the electric heating tube circuit is very important.

Specification and model

1. Voltage, power

2. Pipe diameter, usually 8mm, 10mm, 12mm, 16mm, 20mm

3. Flat flange: GB/T 9119-2010 plate type flat welded steel pipe flange, commonly used sizes include: DN65-DN80-DN100-DN125-DN150-DN250, etc. Different flange standard sizes are selected according to different pressure pressures. Of course, in the design and production process, in order to reduce costs, the flange thickness may be changed without affecting the service life. For specific details, please consult sales personnel.

4. Usually composed of U-shaped pipes such as 1, 2, 3, 6, 9, 12 (usually multiples of 3), which are welded to the flange by TIG argon arc welding

5. Material selection for tube casing: The main materials include 10 # carbon steel, SUS304, SUS321, SUS316L, SUS310S (commonly known as 2520), titanium tube, etc.

6. Selection of Pipe Shell Sheath: Metal pipe materials can be coated with anti-corrosion or anti scaling coatings on the surface of the shell, effectively enhancing corrosion resistance and anti scaling performance.

7. Tube shell sheathing process: liquid spraying and electrostatic powder spraying are available for selection. The heating tube coated with electrostatic powder directly solves many problems of PTFE sleeve heating tubes and can be completely replaced, resulting in better results.

8. Material of flange: 10 # carbon steel, SUS304, SUS321, SUS316L

9. Junction box: available in either ordinary fiberglass casing or explosion-proof casing
