Heat trace design with material list
Here you can do trace heating design for pipelines with selfregulating
The calculation of heat losses is done with the following
Qv= (2 * pi * lambda * (Th - Tmin)) / (ln * (D/d))
Qv Heat loss(W/m)
lambda Thermal conductivity (W/mK)
Th Maintain temperature (°C)
Tmin Minimum ambient temperature (worst case) (°C)
ln natural logarithm
D pipe diameter including insulation thickness (mm)
(pipe diameter + 2 x insulation thickness)
d Outer pipe diameter without insulation(mm)
Explanantio of the data fields
- please read carefully -
Not all wrong entries will be corrected
For maintain temperature >120°C contact Quintex , please
Please fill out the entry form as completely as possible.. Fields, which are underlined and shown with an * are mandatory for the calculation (s. formula).
Use checkboxes for
the existing entries. The values assigned to the entries will be shown at the related field
to pipes (outer diameter, extra length for valves, supports etc ) and for
insulation (thermal conductivity).
Hint: for a meaningful thickness of the insulation: the thickness of the
insulation should be approx. the nominal pipe diameter. (eg: DN 50 ->
50mm insulation). Please take care for the thermal resistance of the insulation material.
When you have completed your entries, start the design by the appropriate button.
A new window will open with the output data (the input data will be repeated), which are shown on a printer friendly page. If all the data correctly, you can print out the design sheet and use it as a documentation of your heating circuit
If you have to change your input data just go back to the input window in your browser(should be still open). You can close the output window with a button.
