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.

Molybdenum is a silver white metal with an atomic radius of 0.14nm, an atomic volume of 235.5px/mol, a coordination number of 8, and an Az type body centered cubic crystal system with a spatial group of O. No isomeric transformation has been found to date. The lattice parameters of molybdenum at room temperature range from 0.31467 to 0.31475nm and vary with impurity content. Molybdenum has a high melting point and ranks sixth among elemental substances in nature, known as a refractory metal. The density of molybdenum is 10.23g/cm ³， About half of tungsten (tungsten density 19.36g/cm) ³)。 The coefficient of thermal expansion of molybdenum is very low; Molybdenum has a higher thermal conductivity. Low molybdenum resistivity: 5.17 at 0 ℃ × 10 Ω· cm; 24.6 at 800 ℃ × 10
