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
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.

Electric heater element single U-shaped heating tube
The characteristic of U-shaped electric heating tubes is to place electric heating wires inside seamless metal tubes (carbon steel pipes, titanium pipes, stainless steel pipes, copper pipes), and tightly fill the gaps with crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the electric heating wires are connected to the power supply through two lead out rods, and the gaps are filled with magnesium oxide powder with good thermal conductivity and insulation before shrinking the tubes, Because the electric heating tube is curved like the English letter U, it is called a U-shaped electric heating tube. Its specifications can be customized according to user needs, and it has the characteristic of simple structure.

Finned electric heating tubes are made by wrapping metal heat sinks on the surface of ordinary components, which expands the heat dissipation area by 2-3 times compared to ordinary components. That is, the surface power load allowed by finned components is 3-4 times that of ordinary components. Due to the shortened length of the components, their thermal losses are reduced. Under the same power conditions, they have advantages such as fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device volume, and low cost. Designed reasonably according to user requirements for easy installation. The product is widely used in industries such as mechanical manufacturing, automobiles, textiles, food, and household appliances, especially in the air conditioning curtain industry.
