Pencil Heater Element

A cylindrical heating element is described

The classic structure (popular structure) of the tubular heater is the same as the heating tube. It is generally composed of five parts: insulator, sealing material, guide rod, filling material, wire, metal protection tube and terminal.

The metal protection tube is provided with coil wire and guide rod.

Production process:A cylindrical heating element is described

The heating coil wire through the seamless steel pipe, copper or aluminum tube, using filling machine more evenly filled with insulation and thermal oxidation differences in object, such as crystal magnesia powder (such as alumina or clean all the available quartz sand), and then use shrinkage tube diameter machine contract, makes the oxidation medium density (the density is 3.3 g/cubic centimeters of above), to ensure the heating wire cut off air, touch the wall and the center position is not offset.

The heating power can be increased more than 10 times per unit area.

The service life can be increased to more than 10 years. Compared with high-power heating elements, the tubular heater can save 5% materials and the thermal efficiency can reach more than 90%.
