Fin electric heating tube
A finned electric heating tube is a type of electric energy that is converted into heat to heat a material to be heated. During operation, the low-temperature fluid medium enters its input port under the action of pressure through the pipeline, along the specific heat exchange flow path inside the electric heating vessel, and uses the path designed by the fluid thermodynamics principle to take away the high-temperature heat energy generated in the work of the electric heating element. The temperature of the heated medium is raised, and the finned electric heating tube outlet is obtained as a high temperature medium required by the process. The finned tubular electric heating element is a metal heat sink wound on the surface of an ordinary component. Compared with the common component, the heat dissipation area is expanded by 2 to 3 times, that is, the surface power load allowed by the fin component is 3 to 4 times that of the common component. . Due to the shortening of the length of the component, the heat loss of the component is reduced, and under the same power conditions, the utility model has the advantages of rapid temperature rise, high thermal efficiency, long service life, small volume of the heating device and low cost. It can be installed in a blow duct or other stationary, flowing air heating.
Flange electric heating tube
Flange electric heating tube (also called plug-in electric heater): U-shaped tubular electric heating element is adopted. According to the heating medium design specification, it is assembled on the flange cover according to the power configuration requirement, inserted into the material to be heated, and the heating element is working. The large amount of heat emitted is transferred to the heated medium to raise the temperature of the medium to the desired process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater according to the temperature sensor signal, and performs temperature control on the resistive load of the heating element. The medium temperature is made uniform to meet the required requirements; when the heating element is over-temperature or low-level, the interlocking protection device of the heating element immediately cuts off the heating power source to avoid burning of the heating element and prolongs the service life. The flange electric heating tube is mainly used for heat preservation and heating of various storage tanks, containers and fuel tanks in petroleum, chemical, food, machinery and other industries. The connection method can be flanged or threaded face seal.
Titanium electric heating tube
The titanium electric heating tube is made of titanium tube, and the electric heating alloy wire is evenly distributed along the center of the tube. The gap is filled with magnesia sand with good insulation and thermal conductivity. The ends of the tube are sealed with silica gel or ceramic. Highly corrosive liquid for components. Titanium electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Widely used in a variety of highly corrosive liquids. Titanium has a small specific gravity and is widely used in heating water, nitrate solution, acid solution and alkali solution. It has been proved that titanium is highly efficient and has a long service life in the application of anti-corrosion equipment. It does not affect the plating solution in the application of electroplating equipment. Greatly improve the efficiency of the electroplating industry. The effective length of the heating element must be fully immersed in the liquid for use.

Quartz electric heating tube
Quartz heating tubes, most commonly used are carbon fiber quartz heating tubes.
Carbon fiber heating tube, also known as carbon fiber electric heating tube, infrared heating tube, infrared electric heating tube, carbon fiber infrared electric heating tube, carbon fiber infrared heating tube and so on. It is to place a carbon fiber filament in the quartz tube, vacuum seal in the tube, and put a voltage on the carbon fiber filament to make the carbon fiber filament generate heat to generate heat. The company's products use imported carbon fiber heating elements, with the advantages of large power margin, high temperature resistance, high heat capacity, long service life, and power can be adjusted at will.
Radiant electric heating tube
The radiant heating tube is used to enclose the electric heating element in the protective sleeve to generate heat, and the heat is radiated to the lining and the workpiece to be processed indirectly by the sleeve, and is widely used in various heating furnaces of the heat treatment industry. The electrothermal alloy material used in the radiant heating tube should have a high electrical resistivity and a high electrothermal conversion rate. Since the radiant tube is placed in the casing, the heat transfer process is different from that of the general open type electric heating element, and the heat shielding is large, and the temperature of the component must be controlled during the heating process to prevent the component from being overheated. When the radiant tube is closed and heated, the surface temperature of the electric heating element is about 100 ° C - 150 ° C higher than the furnace temperature. Therefore, when selecting materials, it is necessary to analyze the furnace temperature, the temperature inside the furnace, and select the correct heating material.
