Heating Tube Product Features
Stainless steel electric heating tube uses a metal tube as the shell, with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) uniformly distributed along the center axis inside the tube. The gaps are filled and compacted with magnesium oxide sand that has good insulation and thermal conductivity. Both ends of the tube are sealed with silicone or ceramic. Stainless steel electric heating tubes are electrical components specifically designed to convert electrical energy into heat energy. Due to their low price, ease of use, convenient installation, and no pollution, they are widely used in various heating applications. The service life of stainless steel electric heating tubes is very long, generally designed to last over 10,000 hours.
