Description

Parameters required for non-standard ordering of double-headed electric heating pipes Fan Coil Unit Heaters:

1. Diameter of electric heating pipe: Φ5.5~ Φ30

2. Electric heating pipe materials: such as SUS201, SUS304, SUS321, SUS316L, SUS310S, stainless steel anti-scaling coating treatment, titanium pipes, etc., customized according to customer requirements.

3. Input power and power: customized on demand

4. Length of electric heating tube: customized on demand

5. Others: working environment, length of terminal or lead (conventional: 300mm), whether to install thread (thread size), etc.

1. Product introduction of the double head tube

The double-ended electric heating pipe is an electric heating pipe with a double-ended outlet. The metal pipe is used as the protective shell (including stainless steel, red copper pipe, and various types of steel), and the spiral electric heating alloy wire (nickel-chromium) is evenly distributed along the inner axis of the pipe. , iron-chromium alloy heating wire), and the gap is tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation, and both ends of the nozzle are sealed with silica gel, which is processed by other processes. The heater has the characteristics of simple structure, easy installation, and long service life. With its strong advantages, it is widely used in air heating, metal mold, and various liquid heating.

2. Classification of double-headed tubes

Double-headed electric heating pipes are generally divided into U-shaped electric heating pipes, threaded installation electric heating pipes, double-headed finned electric heating pipes, double-headed electric heating pipes, water heater heating pipes, etc.

3. The use environment of the double-headed tube

Double-head electric heating tube used in the air: 1. Closed air heating 2. Air heating 3. Special gas heating

The use of double-head electric heating tubes in liquids: 1. Heating in water 2. Heating in oil 3. Heating acid and alkali liquids (the heating area of the electric heating tube should be immersed and not exposed to the air) The watt density and material used are different and should not be confused Use, a good use environment should not produce peeling, thinning, oily, watery and other phenomena.

Fourth, the calculation of the resistance of the double-head electric heating tube

Example: 220V1500W electric heating tube

P=1500 watts (power) U=220 volts (voltage) Find: I (current)

I=P/U=1500/220≈6

Ohm's Law Find: R (Resistance)

R=U/I=220/6.82≈32.27 Euro

5. Precautions for the use of double-headed electric heating tubes

1. The components should be stored in a dry place. If the insulation resistance drops to less than 1 megohm due to long-term storage, it can be dried in an oven at about 200°C for several hours (or the low voltage of the components is passed for several hours), that is, the insulation may be restored. resistance.

2. When carbon deposits are found on the surface of the tube, remove it and use it again, so as not to reduce the efficiency or even burn out the components.

3. When melting solid oils such as asphalt and paraffin, the voltage should be reduced, and then the rated voltage should be increased after melting. Avoid the concentration of electricity and reduce the service life of components
