Electric heating tube material requirements
1. Among the factors affecting the quality of electric heating tubes, the quality of materials accounts for a very important reason. 2. Reasonable selection of raw materials for electric heating tubes is the prerequisite for ensuring the quality of electric heating tubes.
3. Selection principle of tube materials: temperature resistance, corrosion resistance.
4. Selection of resistance wire: Cr20Ni80
5. Selection of magnesium oxide powder: industrial grade magnesium oxide powder
6. Selection of sealing material: silicone oil + 704 sealant
Electric heating tube applications
1. Small size, high power: This electric heater mainly uses clustered tubular heating elements internally, with each clustered tubular electric heating element having a maximum power of up to 5000KW.
2. Fast thermal response, high temperature control accuracy, high overall thermal efficiency.
3. Wide application range, strong adaptability: This circulating heater can be used in explosion-proof or ordinary occasions, with explosion-proof grades up to B and C, and pressure resistance up to 10Mpa. The cylinder can be installed vertically or horizontally according to user needs.
4. High heating temperature: The maximum working temperature of this heater can reach 850°C, which is not achievable by general heat exchangers.
5. Fully automatic control: Through the circuit design of this heater, automatic control of outlet temperature, pressure, flow and other parameters can be easily achieved, and it can be networked with computers for human-machine interaction.
6. Long life, high reliability: This heater is made of special electric heating materials, with reasonable design power load, and multiple protections, greatly increasing the safety and life of the heater.
7. Stainless steel electric heating tubes use a metal tube as the outer shell, with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) evenly distributed along the axial center inside the tube. The gaps are filled and compacted with magnesium oxide sand that has good insulation and thermal conductivity. Both ends of the tube mouth are sealed with silicone or ceramic. This metal-sheathed electric heating element can heat air, metal molds, and various liquids. High-temperature resistance wires are evenly distributed inside a high-temperature resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation. This structure is not only advanced and has high thermal efficiency, but also provides uniform heating. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the metal tube surface, and then transfers to the heated object or air to achieve the purpose of heating.
