Heating Tube Product Features
The stainless steel electric heating tube uses a metal tube as the outer shell, with spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) evenly distributed along the central 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. The stainless steel electric heating tube is an electrical component specifically designed to convert electrical energy into heat energy. Due to its low price, convenient use, easy installation, and no pollution, it is 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.
