Common Characteristics Of Electric Heating Pipe
Jun 26, 2017

1, the component allows to work under the following conditions: A. Air relative humidity is not greater than 95%, no explosive or corrosive gas. b. Operating voltage should not be greater than 1.1 times times the nominal value, the shell should be effectively grounded.

2, the electric heating tube should be positioned fixed, effective heating zone must be immersed in liquid or metal solid, strictly prohibit air burning. found that the surface of the tube body scale or carbon, should be cleaned and reused in time to avoid heat and shorten the life of the film.

3, heating fusible metal or solid nitrate, alkali, bitumen, paraffin, etc., should first reduce the use of voltage, until the medium melted, can rise to the rated voltage.

4, heating the air components should be evenly arranged, so that components have good heat dissipation conditions, so that the flow of air can be fully heated.

5, heating nitrate should consider safety measures to prevent explosion accidents.

6, the wiring part should be placed outside the insulation layer to avoid corrosion, explosive media, water contact; the wiring should be able to withstand the temperature and heating load for a long time, the wiring screw fastening should avoid excessive force.

7, the components should be stored in the dry place, if the long-term placement of insulation resistance below 1m, can be in the 200 Shan around the oven drying, or reduce the voltage ohmic heating, until the restoration of insulation resistance.

8, Electrothermal tube outlet end of Magnesia powder, in the use of the site to avoid contamination and water infiltration, to prevent leakage accident occurred. High-temperature wire, thermocouple, bimetal thermometer, temperature control instrument.
