Product introduction of flanged electric heating tubes: Flanged electric heating tubes (also known as plug-in electric heaters) utilize U-shaped tubular heating elements. Designed in accordance with the specifications for heating different media, they are installed on flange covers based on power requirements, and then inserted into the material to be heated. The large amount of heat generated by these heating elements is transferred to the medium being heated, raising its temperature to meet the desired process requirements. When the medium temperature reaches the set value specified by the process requirements, the control system adjusts the output power of the electric heater based on the signal from the temperature sensor, via PID calculation, in order to control the temperature of the resistive load of the heating element. Even out the medium temperature to meet the required levels ； When the heating element overheats or the liquid level is low, its interlock protection device immediately cuts off the power supply to prevent the element from being damaged, thus extending its service life. Product features of flange electric heating tubes: 1. The surface power of flange electric heating tubes is high, being 2 to 4 times that of the surface load for air heating. 2. The flange electric heating elements are highly dense and have a compact structure. Due to its short and compact design, it has good stability and does not require brackets for installation. 3. In most combined flange electric heating tube systems, argon arc welding is used to connect the electric heating tubes to the flanges; alternatively, fastening devices can be employed – in this case, fasteners are welded to each electric heating tube, which are then secured to the flange cover using nuts. The tubes and fasteners are joined by argon arc welding, ensuring no leaks. A scientific manufacturing process is employed for the fastener seals, making it extremely convenient to replace individual units – thus saving on future maintenance costs. 4. The flange-type electric heating tubes are made from high-quality imported and domestic materials, utilizing scientific production processes and strict quality control to ensure excellent electrical performance.
