Product Description
Electric Heating Tube Product Features Electric heating tube uses a metal tube as the shell, with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) uniformly 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 are sealed with silicone or ceramic. Stainless steel electric heating tubes are electrical components specifically designed to convert electrical energy into thermal energy. Due to their low price, convenient use, easy installation, and no pollution, they are widely used in various heating applications. Stainless steel electric heating tubes have a long service life, typically designed for over 10,000 hours. 1. Voltage can be designed as: 12-660V 2. Single power rating: 50W-20KW 3. Materials: 10# iron, T4 copper, 1Cr18Ni9Ti stainless steel, Ti titanium, etc. 4. Specifications: U-shaped, W-shaped, special-shaped, finned electric heating tubes, explosion-proof electric heating tubes Electric Heating Tube Material Requirements 1. Among the factors affecting the quality of electric heating tubes, the quality of materials plays a very important role. 2. Reasonable selection of raw materials for electric heating tubes is the prerequisite for ensuring their quality. 3. Selection principles for 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 bundled tubular heating elements internally, with each bundled tubular heating element having a maximum power of 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 environments, 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 ordinary heat exchangers. 5. Fully automatic control: Through the circuit design of this heater, automatic control of parameters such as outlet temperature, pressure, and flow can be easily achieved, and it can be connected to a computer network 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 enhancing its safety and service life. 7. Stainless steel electric heating tube uses a metal tube as the shell, with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) uniformly 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 are sealed with silicone or ceramic. This metal-sheathed 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 that has good thermal conductivity and insulation properties. This structure is not only advanced and highly efficient but also provides uniform heating. When current passes through the high-temperature resistance wires, the generated heat diffuses through the crystalline magnesium oxide powder to the metal tube surface, and then transfers to the heated object or air, achieving the purpose of heating.
