Abstract

The apparatus (10) for expanding a pipe incorporates a carrier (1) for several drive rolls (20 - 25) and a unit (6) for transmitting the driving force from a drive shaft (7) to these rolls. To obtain different pipe expansion diameters, the drive rolls can be mounted on the carrier (1) at different radii relative to the axis of the drive shaft.
