Flange-type stainless steel heating tubes are highly dense and compact in structure. Due to the overall short and dense design, they have good stability and require no support during installation.

      The combined type mostly uses argon arc welding to connect the heating tubes to the flange, or it can use a fastening device, where each heating tube is welded with a fastener. Then it is locked with the flange cover using nuts. The tubes and fasteners are welded with argon arc welding, ensuring no leakage. The sealing area of the fasteners adopts a scientific process. Individual replacement is very convenient, greatly reducing future maintenance costs.
       We select high-quality materials from both domestic and international sources. Scientific production processes and strict quality management ensure the superior electrical performance of the heating tubes.
       Overview and working principle: The flange-type stainless steel heating tube (also known as an insertion-type electric heater) uses U-shaped tubular heating elements. According to the design specifications for different heating media and power configuration requirements, it is assembled on the flange cover and inserted into the material to be heated. When the heating element works, the large amount of heat generated is conducted to the heated medium, raising its temperature to meet the required process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater based on the temperature sensor signal through PID calculation, achieving temperature control for the resistive load of the heating element. This makes the medium temperature uniform and meets the requirements. When the heating element overheats or the liquid level is low, the interlock protection device immediately cuts off the heating power to prevent the heating element from burning out, extending its service life.
       Application scope: Flange-type stainless steel 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 sealing.
