Electric heating tubes, also known as heating tubes or heating elements, are scientifically referred to as tubular electric heating element components. They consist of coiled heating wires (resistance wires) placed inside a metallic tube, surrounded and filled in the gaps with insulating powder (MgO) that boasts excellent heat resistance, thermal conductivity, and insulation properties. The ends of the heating wires are fitted with lead rods or leads for connection. They feature simple structure, high mechanical strength, high thermal efficiency, safety, reliability, ease of installation, and long service life. They are widely applicable in various devices such as nitrate tanks, water tanks, oil tanks, acid-base tanks, easy-melting metal melting furnaces, air heating furnaces, drying ovens, drying chambers, and hot press molds.
The electric heating tube is an electrical component specifically designed to convert electrical energy into heat. Due to its affordability, ease of use, installation, and non-pollution, it is widely used in various heating applications.
