Applications and large diameter pipe production facilities around the world are presented. The advantages and disadvantages of pipe production using the JCOE scheme in comparison with the UOE and RBE methods are highlighted. The results of studies of the shape change of a pipe blank during step molding according to the JCO scheme are presented. During the experimental study, a camera was used for photography with further processing in CAD and a photogrammetry system. Based on the results of the experimental study, the coordinates of the points for each step and after final molding, radii along the perimeter of the workpiece, contact and non-contact areas were determined. Modeling of the step molding process was carried out in the DEFORM software package in a flat coordinate system. Based on the results of mathematical modeling, the features of the contact interaction of the workpiece with the deforming tool in the deformation zone were determined and a method for calculating geometric parameters was developed.
