In recent years, cold pipe rolling mills have been used in Ukraine, where it is possible to perform different modes of feeding and turning the pipe. Formulation of the problem. We need a method that makes it possible to plan the cross-wall variation of the pipes. Goal. Development of a method for determining the planned diversity for the design of production technology to ensure the regulated increased quality of pipes according to their geometry. Methodology. Obtaining experimental results on the effect of feeding and turning modes during cold rolling on the cross-wall variation of pipes. Mode 1 – the feed is performed before the forward movement, and the turn before the reverse movement of the cage; mode 2 - the feed is performed before the forward movement, and the turn is performed before the forward and reverse movement of the cage; mode 3 – feeding is performed in the front and back position of the cage, and the turn is in the back position; mode 4 – feeding and rotation are performed before the forward and reverse movement of the cage). The results. Of the tested modes, mode 2 and mode 4 are the most effective (from the point of view of correcting the cross-sectional variation of the pipe blanks. Scientific novelty. First, additional experimental data were obtained on the magnitude of the cross-sectional variation of the pipes during the cold rolling process of the pipes with different modes of feeding and turning in front of the straight and It is shown that the process of cold rolling of pipes with feed in front of the direct and turning before the direct and reverse movement of the cage gives 1.5 times better indicators in terms of tube accuracy compared to feeding in front of the direct movement of the cage and turning before the reverse movement of the cage. Тhe indicators are given by the process with forward and reverse motion of the cage. Practical significance. The obtained results are needed in the development of technologies for the production of pipes with increased requirements for transverse diversity
