High-efficiency stainless steel spiral flange electric heating tubes are widely used for heating liquids in open water tanks, oil wax tanks, acid and alkali tanks, etc. The outlet is sealed with epoxy resin, further improving the ability to cope with high humidity environments. At the same time, the simple structure allows the heater to be freely removed and installed easily. Mainly aimed at 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.

【Detailed Description】

High-efficiency stainless steel spiral flange electric heating tube??Overview:



It is composed of multiple heating tubes welded onto a flange for centralized heating. Mainly used for heating in open or closed solution tanks and circulation systems.



High surface power, 2 to 4 times the surface load of air heating.



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



Most combined types use argon arc welding to connect the heating tubes to the flange, or they can use a fastening device form, where each heating tube is welded with fasteners. Then they are locked with nuts on the flange cover. The tubes and fasteners are argon arc welded, ensuring no leakage. The sealing of the fasteners uses scientific processes. Single tube replacement is extremely convenient, greatly saving future maintenance costs.



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



High-efficiency stainless steel spiral flange electric heating tubeWorking Principle:



It uses U-shaped tubular heating elements, designed according to the specifications for heating different media, assembled on the flange cover according to power configuration requirements, and inserted into the material to be heated. The large amount of heat generated by the heating element during operation 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 of 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 of the heating element immediately cuts off the heating power to prevent the heating element from burning out and extend its service life.
