The process of profiling tubes with rollers was considered. The method of solving the problem was considered. The stress-strain state of the metal in this process was determined, the equations of relative deformations was given, the shear strain intensity in cylindrical coordinates are given for the case of a plane homogeneous deformed state. The stress state index was defined

Keywords: Pipe profiling, deformation, stress, flat pattern, mathematical model, stress concentration, stress-strained state, stress state index
