Tubular Avoid And Corrosive, Explosive
Jul 10, 2017

Tubular electric heater heating tube is installed in the outer tube of electric wire, the gap is filled with good thermal conductivity and insulation of the magnesia powder after the tube, after heat treatment process (individual tube does not need), and then processed into the user The required variety of shapes. It has a simple structure, high thermal efficiency, good mechanical strength, good environment for the poor adaptability. It can be used for heating a variety of liquids and acid salts, but also to adapt to low melting point of metal heating to melt.

The precautions for using the electric heater element are as follows:

1, tubular electric heater electric tube should be fixed positioning, effective heating area must be all immersed in liquid or metal solid, is strictly prohibited air burning. Found that the surface of the pipe body scale or carbon, it should be promptly cleaned and re-use, so as not to affect the heat and shorten the service life.

2, heating fusible metal or solid salt, alkali, asphalt, paraffin, etc., should first reduce the use of voltage until the media melt, to rise to the rated voltage.

3, heating the air when the tubular electric heater components should be evenly arranged cross, so that the components have good heat dissipation conditions, so that the flow of air can be fully heated.

4, the wiring part should be placed outside the insulation layer, to avoid contact with corrosive, explosive media, moisture; lead wiring should be able to withstand long-term wiring part of the temperature and heating load, wire screws should be tightened when tight.

5, tubular electric heater components should be stored in a dry place, if the long-term insulation resistance below 1MΩ, you can dry in about 200 ℃ oven, or reduce the voltage power heating until the restoration of insulation resistance.

Tubular electric heater components are widely used in the field of electric applications in the majority of branches occupy an important position.

Composition and function:

Electric heating tube, also known as heating pipe, heating tube, scientific name tubular electric heater components, is placed in the metal tube winding wire heating wire (resistance wire), and in its surrounding and the gap part of the fill with good heat resistance, Thermal insulation and insulation of the insulating powder (MgO), both ends of the heating wire with the lead out or lead out. Electric heating tube is a special electrical components into electrical energy, because of its cheap, easy to use, easy installation, no pollution, is widely used in a variety of heating occasions.

Features and Applications:

It has a simple structure, high mechanical strength, high thermal efficiency, safe and reliable, easy installation, long service life and so on. Widely used in a variety of nitrite tank, sink, oil tank, acid and alkali tank, fusible metal melting furnace, air heating furnace, drying furnace, drying oven, hot die and other devices.
