380V explosion-proof flange heater electric boiler thermal oil heating tube heater
The outer tube materials generally include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected 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 wire.
The lead terminal materials generally have two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
380V explosion-proof flange heater electric boiler thermal oil heating tube applications:
Mainly used for heat preservation and heating of materials in various storage tanks, containers, and oil tanks in petroleum, chemical, food, machinery and other industries. The connection method can be flange type or threaded end face seal.
Features:
Small size, high power: The heater mainly uses cluster-type tubular electric heating elements. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency. High heating temperature: The design operating temperature of the heater can reach 850°C. The medium outlet temperature is uniform, and the temperature control accuracy is high. 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 improving the safety and 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, pressure can be conveniently achieved, and it can be networked with computers. Significant energy-saving effect: Almost 100% of the electrical energy is transferred to the heating medium.
The explosion-proof electric heater connection flange adopts round flange and square flange (square flange is marked with F after the model), the selected voltage can be 220V or 380V, and a temperature controller can be installed in the wiring chamber. It provides greater convenience for users, with long service life and stable quality.
Product Applications
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, so that the electric heating tube can withstand temperatures up to 900°C, and the electric heating tube will not be damaged when dry-burned under temporary dehydration conditions; and it adopts atmosphere protection blackening mesh belt furnace with 1060°C high-temperature nitriding treatment process, improving the high-temperature resistance and corrosion resistance of the electric heating tube, ensuring service life.
Introduction:
U-shaped tubular electric heating elements are used. According to the design specifications for heating different media, they are assembled on the flange cover according to the power configuration requirements, 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 temperature of the medium to meet the required process requirements.
Tubular electric heating elements (electric heating tubes) use metal tubes as the shell (including stainless steel, copper tubes), with spiral electric heating alloy wires (nickel-chromium, iron-chromium-aluminum) evenly distributed axially along the center of the tube. The gaps are filled and compacted with magnesium oxide sand with good insulation and thermal conductivity, and the tube ends are sealed with silicone. This metal-sheathed electric heating element can heat air, metal molds, and various liquids.
