Go to the tab Pipe type and right-click in the grid. From the menu, select Create new.. The detail form for pipe types now opens. Give your type a name (max. 25 chars recommended), enter the external diameter for the media pipe (mm), the internal diameter for the media pipe (mm), pipe roughness (mm) and U value (W/m°C). Note that the U value (thermal coefficient) relates to the individual media pipe. Indicate that the type is approved for dimensioning. Create the other pipe types that you need.
Also create a type and name it “?” (without ”) and an internal diameter of 0.00 mm, with pipe roughness 0.05 and thermal conductivity 0.25. We set this type for pipes that are to be dimensioned.
(At the end of the manual, you will find a suggestion for pipe types, steel and copper pipes, that you can use as a specimen.)
