Abstract (en)
[origin: US2005000259A1] The present invention concerns a method and a device for reshaping a tube which is mounted between two axially movable pressure rams and which has an initial outside diameter, an initial wall thickness, and an initial length by means of hydraulic pressure produced inside the tube to obtain a finished tube with a different outside diameter or different length, and/or a different wall thickness compared to the initial tube.
