Electric Heating Radiation Tube
Main technologies and performance of electric heating radiation tubes:
1. The error range of the cold resistance of the electric heating wire is ≤ 3%;
2. The insulation resistance between the external protection tube and the heating wire is greater than 2M Ω;
3. Outer diameter of heating tube: from φ 60mm~ φ 300mm in various specifications;
4. Heating power: Various specifications ranging from 2KW/unit to 24KW/unit;
5. The length of the outer tube of the heating tube ranges from 800mm to 2800mm in various specifications;
6. Radiation tube outer wall thickness: various specifications ranging from 1.5mm to 16mm.
