The double U-shaped heating tube is made of a metal tube as the outer shell (including stainless steel and copper tubes), and spiral electric thermal alloy wires (nickel chromium, iron chromium alloy) are uniformly distributed along the central axis of the tube. The gaps are filled and compacted with magnesium oxide sand with good insulation and thermal conductivity. The ends of the tube are sealed with silicone gel. This metal armored heating element can heat air, metal molds, and various liquids.

The spiral heating tube is a tubular electric heating element with a structure in which an electric heating wire is placed inside a metal tube and the gaps are tightly filled with crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the electric heating wire are connected to the power supply through two lead out rods. It has the advantages of simple structure, long service life, high thermal efficiency, good mechanical strength, and can be bent into various shapes for safe use. Using high-quality materials and strict process technology, we produce electric heating tubes with excellent electrical insulation performance and extremely high electrical strength.

Tubular electric heating element (abbreviated as electric heating tube) is an electrical component that specifically converts electrical energy into thermal energy. It is made of metal tubes as the outer shell (including stainless steel and copper tubes), and spiral electric thermal alloy wires (nickel chromium, iron chromium alloy) are uniformly distributed along the central axis of the tube. The gaps are filled and compacted with magnesium oxide sand with good insulation and thermal conductivity. The ends of the tube mouth are sealed with silicone gel. This metal armored electric heating element can heat air, metal molds, and various liquids.

It adopts U-shaped tubular electric heating elements, which are assembled on the flange cover according to the design specifications of different heating 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 transmitted 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 medium temperature uniform and meet the required requirements; When the heating element exceeds the temperature or low liquid level, the interlocking protection device of the heating element immediately cuts off the heating power to prevent the heating element from burning out and prolong its service life.
