Abstract
A method is provided of radially expanding a tubular element. The method comprises inducing the wall of the tubular element to bend radially outward and in axially reverse direction so as to form an expanded section of the tubular element extending around an unexpanded section of the tubular element, wherein said bending occurs in a bending zone of the wall, and wherein an annular space is defined between the unexpanded and expanded sections. At least one guide member is located in the annular space, each guide member being arranged to guide the wall during said bending so that the wall bends at an increased bending radius relative to bending of the wall in case the guide member is absent from the annular space.
