Temperature-controlled explosion-proof electric heating tube waterproof heat transfer oil heating rod Product Application
The electric heating tube is made of high-quality domestic thick-walled seamless stainless steel tube, imported high-temperature magnesium oxide powder and sealing materials from the United States, so that the heating tube can withstand temperatures up to 900°C, and will not be damaged when dry-burned under temporary dehydration conditions; and adopts atmosphere protection blackening mesh belt furnace with 1060°C high-temperature nitriding treatment process, which improves the high-temperature resistance and corrosion resistance of the heating tube, ensuring service life.
Temperature-controlled explosion-proof electric heating tube waterproof heat transfer oil heating rod Heater Process:
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, with high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, generally made of two 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 petroleum, chemical, food, machinery and other industries. Connection methods can be flange type or threaded end face seal.
Features:
Small size, high power: The heater primarily uses clustered tubular electric heating elements. Fast thermal response, high temperature control accuracy, high overall thermal efficiency. High heating temperature: The heater 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 grade 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 life of the electric heater. Fully automatic control: According to requirements, through the heater circuit design, automatic control of outlet temperature, flow, pressure and other parameters can be conveniently achieved, and 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 (square flange add F after model number), selected voltage can be 220V or 380V, and a temperature controller can be installed in the wiring chamber. Providing greater convenience for users, it has a longer service life and stable quality.
Introduction:
Uses U-shaped tubular electric heating elements, designed according to different heating medium specifications, assembled on the flange cover according to 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 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 wire (nickel-chromium, iron-chromium alloy) uniformly distributed along the axial center of the tube, and the gaps are filled and compacted with magnesium oxide sand having good insulation and thermal conductivity. The tube ends are sealed with silicone. This metal-sheathed electric heating element can heat air,
