摘要

The paper presents the methods of obtaining copper pipes by could drawing. The drawing represents a method of plastics cold deformation used to obtain pipes of different diameters and different lengths. Experimentally, are made structure determinations for copper pipes obtained by two techniques: drawing on the mandrel and rolled by specific calibrated rolles. The metallographic structures obtained and the research conclusions are also presented.
