Device for extracting longitudinally welded pipes, has tube forming station, welding station, cooling station and extracting stages, where extracting tool has die with extracting stage

摘要

The device has a tube forming station (3), a welding station (4), a cooling station (5) and extracting stages (I,II,III). An extracting tool (10) has a die with the extracting stage. The unit for rotating a drive of the die is arranged during the extracting process. The rotational speed of the die lies in a range greater than 800 revolutions per minute. An independent claim is included for a method for extracting longitudinally welded pipes.
