Flange electric heating tube (also known as plug-in electric heater): It uses U-shaped tubular electric heating elements, designed according to different heating medium specifications, 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. When the medium temperature reaches the set value of the process requirements, the control system adjusts the output power of the electric heater through PID calculation based on the temperature sensor signal, achieving temperature control of the resistive load of the heating element. This makes the medium temperature uniform and meets the required requirements; when the heating element overheats or the liquid level is low, the interlock protection device of the heating element immediately cuts off the heating power to prevent the heating element from burning out, extending its service life.
2. Purpose of Flange Electric Heating Tube
Flange heating tubes are 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. The connection method can be flange type or threaded end face seal.
3. Application Range of Electric Heating Tube
1. Flange electric heating tube mold heating has been widely accepted by customers in modern industrial applications.
2. Flange electric heating rod in plastic machinery heating systems.
3. Flange heating tube can be used in pharmaceutical production lines.
4. Flange heating tube can be used in laboratory heat treatment experiments.
5. Flange heating tube in chemical fields, etc.
Flange electric heating tube is composed of multiple heating tubes welded on a flange for centralized heating. It is mainly used for heating in open or closed solution tanks and circulation systems.
4. Flange Heating Tube
1. Flange heating rod has high surface power, which is the surface load of air heating.
2. Flange heater is highly dense and compact. Due to its short and dense overall structure, it has good stability and does not require a bracket for installation.
3. Flange electric heating rod combination mostly uses argon arc welding to connect the electric heating tube to the flange, or it can be in the form of a fastening device, where each electric heating tube is welded with a fastener, and then locked with the flange cover using nuts. The tube and fastener are welded by argon arc welding, and the sealing part of the fastener adopts scientific technology, making single tube replacement more convenient.
5. Product Name: High Power Water Tank Flange Heating Tube
5. Precautions for Flange Electric Heating Tube
1. The element is allowed to work under the following conditions:
(1) Relative humidity of air is not high
(2) Working voltage should not exceed the rated value, and the shell should be effectively grounded.
2. When the heating medium is liquid, the effective length (H1 or H2) of the element must be fully immersed in the liquid. The heating part of the element should have a certain distance from the container wall.
3. Elements for heating liquids should not be used to heat gases or solids.
4. For elements heating liquids, if scale or carbon deposits are found on the tube surface, they should be cleaned before use.
5. When heating light metals or nitrates, alkalis, asphalt, paraffin, etc. in solid state, start with reduced voltage, and only increase to rated voltage after the solid heating medium is completely melted.
6. Safety measures should be considered when heating nitrates.
7. The wiring part of the element should be placed in the insulation layer, and the outlet end must be kept dry and clean outside the heating chamber to avoid flashover or short circuit. Do not use excessive force when wiring.
8. A small amount of paste may overflow from the end of the element. This is sealing material and does not affect use. After power off, wipe the overflow clean.
9. The element should be stored in air circulation.
10. If the element is not used for a long time after a period of use and becomes damp, it can be baked in a drying oven or directly heated by reducing voltage to remove moisture until normal.
