On the basis of the conducted researches possibility of unpunch of the group holing of openings the hydrodynamic stamping is well-proven in tubular purveyances with certain limitations, related to durability of rigging which at a ladening from within by pressure over 500 Mpa is deformed plastic. The row of new of principle charts of unpunch of the group holing of openings is developed by the method of GDSH, the theoretical method of determination of parameters of the external loading is developed for the indicated processes and the program of machine account is developed.
