Characteristics of metal tubular electric heating tube

The biggest feature of the metal tubular electric heating tube is that the surface is not charged when it is energized and heated. Due to its structural characteristics, the metal tubular electric heating element has many advantages over other forms of electric heating elements. Moreover, it has long service life, high mechanical strength, high efficiency, saves electricity, and is safe to use. It can be bent into various shapes.

Electric heating tube, also known as heating tube, heating tube, scientific name tubular electric heater element, is a coiled heating wire (resistance wire) placed in a metal tube, and filled with good heat resistance, Thermally conductive and insulating insulating powder (MgO), both 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. It is widely used in various saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot stamping molds and other devices.
