The Austrian patent no. 134543 deals with a pipe with fins, which should increase the flow rate in comparison to a smooth pipe without fins. There are no scientific papers published for this patent. The presented master thesis may be a basis for future research. The dimensions and the location of the fins are as precisely as possible reconstructed. Two versions of fins were designed, constructed and tested. In the lab tests the pressure difference (friction losses) for pipes equipped with the different fins and without fins was measured. In the pipes of length 3,60 m 18 fins were installed. The results showed that for one fin type the differential pressure was marginal higher compared with the measurements of the pipe without fins, where as the second fin type had a significant higher pressure loss. Consequently, the lab test didn`t show an increase in the flow rate.
