Abstract
A process for cold pilger rolling of thin-walled pipes having small outer diameters in which calibrated rolls are moved along the intermittently stationary pipe, inside of which a roll mandrel which is likewise calibrated assists in the shaping of the inner and outer pipe in the shaping region. To produce pipes which are thinner and have thinner walls than was formerly possible, the pipe to be shaped and the shaping tools (rolls and roll mandrel) are warmed up to operating temperature before and/or during the starting rolling phase of the pipes to be shaped.
