30KW Flange Heating Tube
 
 
Product Description:
 
 
Flange-type electric heater (also known as plug-in electric heater) uses U-shaped tubular heating elements. According to the design specifications for different heating media, it is assembled on the flange cover based on power configuration requirements and inserted into the material to be heated. When the heating element operates, the large amount of heat generated is conducted to the heated medium, raising its temperature to meet the required process conditions. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater through PID calculation based on the temperature sensor signal, achieving temperature control for the resistive load of the heating element..This ensures uniform medium temperature to meet the required specifications. When the heating element overheats or the liquid level is low, the interlock protection device immediately cuts off the heating power supply to prevent damage to the heating element, extending its service life.


Flange-type electric heaters 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.


Mainly used for heating in open or closed solution tanks and circulation systems. It has the following advantages:
① High surface power, 2 to 4 times the surface load of air heating.
② Highly dense and compact structure. Due to its short and dense overall design, it has good stability and requires no support for installation.
③ Most combined types use argon arc welding to connect the heating tube to the flange, or use a fastening device where each heating tube is welded with a fastener. Then, the flange cover is locked with nuts. The tube and fastener are argon arc welded, ensuring no leakage. The sealing area of the fastener uses scientific technology. Single tube replacement is extremely convenient, greatly reducing future maintenance costs.
