Clad pipes are widely used worldwide for transportation of oil and gas under conditions of exposure to aggressive media. The article investigates the issue of joint deformation of nickel alloy and steel of strength class K60 during production of rolled heavy plates on the industrial plate mill. The rheological properties of the constituent materials were determined, the mathematical model based on the finite element method was developed; it allowed to determine the dependence of deformation ratio of the layers on the total deformation of the billet. Accuracy of the results obtained using simulation is confirmed by comparison with the results of industrial rolling. The obtained relationships allow proper selection of the initial thickness of the stainless layer billet, which provides the required final thickness of the clad layer.

The studies were carried out within the program of the Russian Federation of strategic academic leadership "Priority-2030" aimed at supporting the development programs of educational institutions of higher education, the scientific project PRIOR/SN/NU/22/SP5/26.
