Tubular electric heating element (referred to as electric heating tube) is a kind of electrical element that specializes in converting electrical energy into heat energy. It is a metal tube as the shell (including stainless steel, copper tube), along the center of the tube axial uniform distribution spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) its void filling compaction with good insulation and thermal conductivity magnesia sand, both ends of the pipe mouth sealed with silicone, this metal armored electric heating element can heat air, metal molds and various liquids. Common electric heating tubes include finned electric heating tubes, finned electric heating tubes, finned electric heating tubes, Teflon electric heating tubes, quartz electric heating pipes and so on. Because of its cheap price, easy to use, easy to install, no pollution, it is widely used in various heating occasions.
