Abstract (English):
The process flow diagram and ratios for calculating the modes of molding torodial tank shells by gas pressure are de-scribed. The work material is assumed to be anisotropic, exhibiting viscous properties (creep flow) under conditions of hot working. The Laplace equilibrium equation is used to calculate gas pressure. Damaging assessment of the work material was made according to the damaging kinetics equations. The calculated results on the mode of gas molding technology are given.

Keywords:
