摘要： The invention relates to a method 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 tubular section extending around an unexpanded section of the tubular element, said wall having a resistance to radially outward bending and a resistance to stretching in circumferential direction. Said wall is provided with at least one of primary means for increasing the resistance to radially outward bending of the wall, and secondary means for reducing the resistance to stretching in circumferential direction of the wall.
