Introduction to heating tube terminology (1)

The heating tube is a metal tubular heating element. The heating tube uses a metal tube as a shell, an alloy electric heating wire as a heating element, and a lead wire (rod) at one or two ends. The metal tube is filled with a dense magnesium oxide powder insulating medium for fixing The heating element of the heating element.

  1. Leading rod of the heating tube (line)

The heating tube lead rod (line) refers to the metal conductive parts connected with the heating element for the connection of the heating tube and the power supply, and the heating tube and the element heating tube.

  2. Expanded length of the heating tube (mm)

The expanded length of the heating tube refers to the sum of the length of the straight line and the curved part of the metal tube on the heating tube pattern.

  3. Heating length of the heating tube (mm)

The heating length of the heating tube refers to the length of the part where the heating element is arranged on the heating tube pattern.

  4. The heating surface area of the heating tube (c㎡)

The heating surface area of the heating tube refers to the surface area of the metal tube on the heating length.

  5. Surface load of heating pipe (w/c㎡)

The surface load of the heating tube refers to the power per unit area on the heating surface.

  6. The heating tube is a fully heated condition

The fully heated condition of the heating tube refers to the working condition for the heating tube to reach the specified working state.
