The difference between single-head electric heating tube and double-head heating tube

1. Different structure

 

   The single-head electric heating tube is an electric heating tube element with one end of the wire. It has good insulation properties and is filled with high-purity magnesium oxide powder with high thermal conductivity. It has small size, high power, fast heat dissipation, and thermal efficiency. Higher characteristics.

 

   The double-ended heating tube is an electric heating tube with two ends, with a metal tube as a protective shell (including stainless steel, copper tube, various imported steel materials), and a spiral high-quality electric heating alloy wire (iron-chromium-aluminum alloy wire) is evenly distributed along the central axis of the tube. , Nickel-chromium alloy wire), and tightly fill the gap part with crystalline magnesium oxide powder with good heat resistance, high heat resistance and insulation. The two ends of the nozzle are sealed with silica gel, and then processed by other processes.

 

 2. Power design

 

   With the same length and pipe diameter, the power of the single-head heating tube is greater than that of the double-head heating tube, but in terms of service life, in the same environment and the same specification, the single-head heating tube has a longer service life.

 

   Example: In the case of air dry burning, a single-head heating tube with a tube diameter of 16mm and a tube length of 300mm can achieve 550W; while the power of a double-ended electric heating tube with the same tube diameter and length can only achieve 300W.

 

   Therefore, the surface load of the single-ended electric heating tube is higher than that of the double-ended electric heating tube.
