1. Voltage and power
(1) Determine the rated voltage of the flange electric heating pipe (reference:)
(2) Determine the power of the flange electric heating tube (reference:)
2. Pipe diameter (corresponding to A in the drawing)
3. Unilateral length: B (how long is the cold zone? How long is the heating zone?)
4. Peripheral diameter of heating pipe: C (that is, the opening size of the customer box must be greater than C)
5. Flange size: flange outer diameter D number of bolt holes bolt hole diameter bolt hole center distance: E
5. Working environment (heating medium), working temperature
6. Heating pipe material and flange material
7. Special requirements: For example, resistance wire material, terminal material, cold zone length, wiring cover material selection (ordinary glass fiber reinforced plastic or explosion-proof cover) and support board requirements, etc.
