According to the use environment, it can be divided into:
Air use: 1. Closed air heating; 2. Circulating air heating; 3. Special gas heating.
Use in liquid: 1. Heating in water; 2. Heating in oil; 3. Heating in acid-base liquid (the heating zone of electric heating tube should be immersed into the heating zone, and should not be exposed to air burning). The wattage density and material used are different and can not be confused. In a good use environment, there should be no skin, thinning, dust, oil and water.
Use of acid, alkali and gas:
Copper tube, SUS304 ? 316 tube for neutral environment, Incoloy nickel alloy tube for weak acid and weak alkali environment, Ti alloy tube for medium acid and alkali environment, quartz, Teflon Teflon tube and Incoloy nickel alloy tube for strong acid and alkali environment, SUS316 ? tube for 900 ℃, SUS304 ? tube for 700 ℃, Incoloy nickel alloy tube for 650 ℃, Ti titanium alloy tube for 300 ℃ environment, and te for environment below 110 ℃ Flon Teflon tube. Due to the variety of heating gas and liquid and the diversity of application range, please contact the professional who is familiar with the chemical characteristics before use.
Sealing materials are as follows:
(1) The high temperature electric heating tube is sealed with silicone oil and can withstand high temperature of 700 ℃. The disadvantage is that it can not completely prevent the infiltration of liquid and moisture.
(2) Silicon seal can prevent liquid from seeping into the tube when using electric heating tube at medium and low temperature. The disadvantage is that it can only bear working temperature of 220 ℃ and instantaneous temperature of 250 ℃.
(3) When the electric heating tube is used at low temperature, it can prevent moisture and liquid from seeping into it. The disadvantage is that it can only bear the working temperature of 150 ℃ and the instantaneous temperature of 185 ℃.
Due to process factors, the scores were as follows:
Due to process factors, there are 5cm non heating areas at both ends of the double head electric heating tube. If it is necessary to lengthen the non heating area, please inform before ordering. If the watt density is too high, fin fin fins can be added to increase the heat dissipation effect.
Pipe wiring method is divided into:
The wiring method of double head electric heating tube has Y - △ type wiring, which belongs to three-phase voltage, and the series and parallel wiring belongs to single-phase voltage. When wiring, please select the appropriate heat-resistant wire according to the temperature of the wiring area, and the terminals shall be locked to avoid short circuit, causing leakage of equipment and burning of electric heating tube. |
