Manufacturing method for pipes/tubes, e.g. to be used in heat-exchangers, has two or more metallic ribbons running through a relief train/train mill

摘要

Metallic ribbons (A-C) fit on a relief train/train mill, helped by a device with predetermined breaking points (S). The ribbons are reshaped, merged into a pipe/tube and finally separated off as single pipes/tubes at the predetermined breaking points previously harmonized. Ribbons running through the relief train/train mill are scanned by scanning tools (K1-K3) regarding the positions of the predetermined breaking points. An independent claim is also included for a relief train/train mill for carrying out a method for manufacturing pipes/tubes.
