SELEKTOR

Free software for calculation of flange joints.

The KRAJ SELEKTOR is a useful tool for the design and calculation of flange-bolt circular connections. The program allows you to use databases of standard flanges according to EN PN and ASME standards, as well as for the analysis of your own designed structures. The user can use the data contained in the extensive databases or own data not included in the databases. The system allows data and results to be saved in PDF format to a selected medium or directory.
