Drawing pipes
...
The thermal losses can also be added to the pipes. If you click on the pencil on the right in the main parameter list, the pop-up shown below will appear. The classes that can be selected are based on the German standard DIN EN 12828.
The isolation value changes depending on the pipe diameter, this is shown in the table below for class 1 to class 6. The thermal losses will be calculated during a dynamic simulation in function of the pipe length, pipe diameter, isolation class en the environment temperature.

After the action "compute design flows" you go to the next step "Select pipes"
The selection of the pipes is based on the following standard
- Steel pipes (welded): NBN EN 10255
- Steel pipes (presicion): NBN EN 10305-1 en NBN 10305-2
- Copper pipes: NBN EN 1057
- Multilayer: NBN EN ISO 21003-2
In the figure below you see the selection of steel pipes of a Hysopt-model.
It is possible to change the pipe diameter manually. For example if you have a large amount of DN32 pipes and a small amount of DN25 pipes, the user can manually change the DN25 into a DN32.
