Temperature-controlled Explosion-proof Electric Heating Tube Waterproof Thermal Oil Heating Rod Product Application
The electric heating tube uses high-quality domestic thick-walled seamless stainless steel tubes, imported high-temperature magnesium oxide powder from the United States, and sealing materials, allowing the heating tube to withstand temperatures up to 900°C. The heating tube will not be damaged even when dry-burned under temporary dehydration conditions. It also adopts an atmosphere-protected blackening mesh belt furnace with 1060°C high-temperature nitriding treatment process, improving the high-temperature resistance and corrosion resistance of the heating tube, ensuring a long service life.
Temperature-controlled Explosion-proof Electric Heating Tube Waterproof Thermal Oil Heating Rod Heater Process:
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low-carbon steel, etc.
Magnesium oxide powder is selected in different specifications according to different usage requirements, including high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, and there are generally two types of materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally have two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Applications:
Mainly used for heat preservation and heating of materials in various storage tanks, containers, and oil tanks in industries such as petroleum, chemical, food, and machinery. Connection methods can be flange type or threaded end face sealing.
Features:
Small size, high power: The heater primarily uses bundled tubular electric heating elements. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency. High heating temperature: The heater's design operating temperature can reach 850°C. Uniform medium outlet temperature, high temperature control accuracy. Wide application range, strong adaptability: The heater can be used in explosion-proof or ordinary places, with explosion-proof grades up to dⅡB and C, and pressure resistance up to 20MPa. Long life, high reliability: The heater is made of special electric heating materials, with low design surface power load and multiple protections, greatly enhancing the safety and service life of the electric heater. Fully automatic control: According to requirements, through the heater circuit design, automatic control of parameters such as outlet temperature, flow rate, and pressure can be conveniently achieved, and it can be networked with computers. Significant energy-saving effect: Almost 100% of the heat generated by electricity is transferred to the heating medium.
The explosion-proof electric heater connecting flange adopts round flange and square flange forms (add F after the model for square flange), with selectable voltages of 220V or 380V, and a temperature controller can be installed in the wiring chamber. It provides greater convenience for users, with a longer service life and stable quality.
Introduction:
Uses U-shaped tubular electric heating elements. According to the design specifications for heating different media, they are assembled on the flange cover according to power configuration requirements and inserted into the material to be heated. The large amount of heat generated by the heating element during operation is conducted to the heated medium, raising the medium temperature to meet the required process requirements.
(Electric heating tube) uses a metal tube as the outer shell (including stainless steel, copper tube), with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) uniformly distributed along the axial center of the tube. The gaps are filled and compacted with magnesium oxide sand that has good insulation and thermal conductivity. The tube ends are sealed with silicone. This metal-sheathed electric heating element can heat air,
