Rolling the shell in a rough pipe by profiling roll on a mandrel on a Pilger rolling mill and final rolling of the rear end of the shell on the area of the mandrel shank of increased diameter to form the Pilger head. Piercing the billet is performed by thinning the rear end of the shell from the side of inner diameter. Rolling the shell in the rough pipe by profiling rolls is carried on a mandrel, the generator of the shank of which under Pilger head and generator of the area of the rear end of the shell with increased inner diameter are congruent and made along a straight line.
