Electric heating tube, also known as heating tube or heating tube, also known as tubular electric heater element, is a type of heating wire (resistance wire) placed in a metal tube and filled with insulating powder (MgO) with good heat resistance, thermal conductivity, and insulation around and in the gaps. The two ends of the heating wire have lead out rods or lead out wires. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. Widely applicable to various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, melting furnaces for fusible metals, air heating furnaces, drying furnaces, drying boxes, hot pressing molds and other devices. Electric heating tubes are electrical components that specifically convert electrical energy into thermal energy. Due to their low price, convenient use, easy installation, and pollution-free nature, they are widely used in various heating situations. Tubular electric heating element (electric heating tube) is an alloy wire (nickel chromium, iron chromium alloy) with a metal tube as the outer shell (including stainless steel and copper tubes), uniformly distributed along the central axis of the tube for spiral electric heating. The gap is filled and compacted with magnesia sand with good insulation and thermal conductivity, and the ends of the pipe mouth are sealed with silicone. This metal armored electric heating element can heat air, metal molds, and various liquids. According to the classification of outlet methods, it can be divided into single head electric heating tubes and double head electric heating tubes
