Flange type electric heater factory

Flange type electric heaterIt is heated centrally by welding multiple heating tubes onto the flange.

Mainly used for heating in open and closed solution tanks and circulation systems. It has the following advantages:

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

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

Combination welding is mostly carried out using argon arc welding methodElectric heating tubeFor flange connection, fastening devices can also be used, that is, each electric heating tube is welded with fasteners. Then tighten the flange cover with nuts. The pipe and fasteners are welded using argon arc welding, ensuring no leakage. The sealing of fasteners adopts scientific technology. Single replacement is extremely convenient, greatly saving future maintenance costs.

Choose high-quality imported and domestic materials. Scientific production processes and strict quality management ensure superior electrical performance of electric heating tubes.

Overview and Working Principle

Flange styleElectric heater(also known as plug-in electric heater): It uses U-shaped tubular electric heating elements, which are assembled on the flange cover according to the design specifications for heating different 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 conducted 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 temperature of the medium uniform and meet the required standards; When the heating element exceeds the temperature or reaches a low liquid level, the interlocking protection device of the heating element immediately cuts off the heating power supply to prevent the heating element from burning out and extend its service life.
