| Abstract: | Defects such as thinning out of tube, ovalization of tube cross section and wrinkling at bend are often found during the process of roll forming of copper thin-wall tubes. Theoretical analysis was made on the causes and then preventive measures and the way out were put forward according to theory and work experiences. Practical production proved the correctness and feasibility of the theory. |
| Keywords: | pipe bender copper thin-wall tube wrinkle defects preventive measure |
