Quality of cold-formed pipes should be improved. In connection with this, indices of the quality should be determined. Some indices of the quality have been suggested. Mathematical models connected characteristics of stressed-strained state with indices of the quality have been developed with the use of integral equations. Modeling of accuracy of the pipes has been performed. It has been shown that non-uniform scheme of processing the pipes can be applied. Processing of the pipes in cold rolling mills has been considered. Drawing of copper and brass pipes has been described. Version of solving the problem of prediction of quality indices has been suggested.
