FAQ

It adopts U-shaped tubular electric heating elements, which are assembled on the flange cover according to the design specifications of different heating media and power configuration requirements. It is inserted into the material to be heated, and the large amount of heat emitted by the heating element during operation is transmitted to the heated medium, causing the temperature of the medium to rise and meet the required process requirements. When the medium temperature reaches the set value required by the process, the control system will adjust the output power of the electric heater based on the temperature sensor signal and PID calculation to achieve temperature control of the resistive load of the heating element. Make the medium temperature uniform and meet the required requirements; When the heating element exceeds the temperature or low liquid level, the interlocking protection device of the heating element immediately cuts off the heating power to prevent the heating element from burning out and prolong its service life.

Features:

1. The surface power is high, which is 2-4 times the surface load of air heating.

2. Highly dense and compact in structure. Due to its short and dense overall length, it has good stability and does not require a bracket for installation.

3. Combination types mostly use argon arc welding to connect the electric heating tube to the flange, or a fastening device can be used, that is, each electric heating tube is welded with fasteners, and then locked with the flange cover using nuts. The tube and fastener are welded using argon arc welding to never leak. The sealing of fasteners adopts scientific technology, making single replacement extremely convenient and greatly saving future maintenance costs.

4. Selecting high-quality imported and domestic materials, scientific production processes, and strict quality management ensure the superior electrical performance of electric heating tubes.

Engineered for superior thermal management in pressurized systems, our Flange Electric Heating Tube delivers powerful, concentrated heat directly into process media. Its defining feature is a solid metal flange—available in circular, square, or triangular shapes—that bolts directly to a matching tank or vessel opening. This secure mechanical connection provides stable mounting and excellent heat dissipation from the base, making it a preferred choice for high-wattage applications.

The versatility of the Flange Electric Heating Tube is unmatched. We manufacture these heaters with a wide selection of sheath alloys, power ratings, and immersion lengths to suit diverse fluids, including corrosive chemicals, viscous oils, and water. Whether you require a single-tube design or a complex multi-tube assembly bundled on a common flange, our engineering team can configure a solution that maximizes efficiency and meets your spatial constraints.

Durability and safety are paramount. Every Flange Electric Heating Tube undergoes rigorous testing to ensure integrity under thermal cycling and mechanical stress. The sealed construction prevents moisture ingress, while the flange acts as a heat sink, protecting gaskets and mounting surfaces from excessive temperatures. This design prioritizes both operational safety and equipment longevity.

Implementing a Flange Electric Heating Tube significantly enhances process control and energy efficiency in systems like reactors, storage tanks, and melting pits. For complex installations, our experts can assist in selecting the optimal flange configuration, heating element layout, and control strategy to achieve perfect, reliable heating performance tailored to your industrial process.
