The methodology of verification of simulation results on full-scale pipes is discussed. The adequacy of theoretical models is proved by the coincidence of a set of parameters with experimental results, which allows us to recommend theoretically developed models for use. In addition, new scientific results have been obtained in the experiments, in particular, parameters were determined that allow confirming the reliability of obtained pipes in terms of the plasticity resource of their material at dangerous points. The versatility of the proposed verification method allows us to recommend it for a wide range of tasks related to modeling the plastic working processes.
