Aluminum Cast Heater introduces the overview and working principle of flange electric heating tubes
Flange electric heating tube (also known as insertion-type electric heater): It uses U-shaped tubular electric heating elements. According to the design specifications of the heating medium and the power configuration requirements, it is assembled on the flange cover and inserted into the material to be heated, and the heating element can work. The large amount of heat emitted is transferred to the heated medium to raise the temperature of the medium to the required process requirements.
The flange electric heating tube is made of a metal tube as a foreign object, filled with high-resistance electric heating alloy wire as the heating material, and filled and compacted around the heating wire. It has good insulation performance, and high-purity magnesium oxide with high thermal conductivity is used as a filler. This flange electric heating tube product has the characteristics of large natural power, high thermal efficiency, and fast heat dissipation.
When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater according to the temperature sensor signal, and performs temperature control on the resistance load of the heating element. Make the medium temperature uniform to meet the requirements. When the temperature of the heating element is too high or too low, the interlock protection device of the heating element will immediately cut off the heating power supply to avoid burning out the heating element and extend its service life.
Why are flange electric heating tubes so popular?
The flange electric heating tube evenly distributes high-temperature resistant electric wires in high-temperature resistant stainless steel seamless tubes, and densely fills the gap parts with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. The flange electric heating tube not only has advanced structure, but also high thermal efficiency. And the heat distribution is uniform. When the current flows through the high-temperature resistance wire, the heat generated by the flange electric heating tube is diffused to the surface of the metal tube by the crystalline magnesium oxide powder, and then transferred to the heated part or air, thereby achieving the purpose of heating.
Flange electric heating tubes are generally popular with customers. Whether it is water tank heating or heat transfer oil heating, as long as it is immersion heating, you like to use flange electric heating tubes. So, what makes flange electric heating tubes so popular? Below, the Copper Cast Heater manufacturer will introduce the relevant content to you
Generally speaking, a high-power electric heating tube is actually a combined electric heating tube composed of multiple single U-shaped electric heating tubes, also known as a flange electric heating tube. This kind of flange electric heating tube is actually very common and is usually suitable for closed and open mechanical equipment.
The advantages of flange electric heating tubes are not as simple as one plus one; its working efficiency is improved geometrically. Let's first understand the characteristics of flange electric heating tubes:
Flange electric heating tubeis made of U-shaped stainless steel electric heating tubes, assembled on a stainless steel flange cover according to the design specifications for different heating media and power configuration requirements. It is convenient to use and has a long service life!
The flange heating tube is composed of multiple heating tubes welded onto a flange for centralized heating. Flange electric heating tubes are mainly used for heating in open or closed solution tanks and circulation systems. Advantages: high surface power, which is 2 to 4 times the general electric heating surface load, highly dense, and compact structure. Due to the overall short and dense structure, it has good stability and does not require a bracket for installation. Most flange electric heating tubes use argon arc welding to connect the heating tube to the flange, or they can use a fastening device form, where each heating tube is welded with a fastener. Then it is locked with nuts on the flange cover. The tube and fastener are welded with argon arc welding, ensuring no leakage. The sealing part of the fastener adopts a scientific process. Single-tube replacement is extremely convenient, greatly saving future maintenance costs. Imported and domestic high-quality materials are selected. Scientific production processes and strict quality management ensure the electrical performance of the heating tube.
