A method is provided of expanding a tubular element from a first inner diameter to a second inner diameter larger than the first inner diameter. The method comprises the steps of: a) installing a sleeve of flexible material in the tubular element; b) installing an expander in the tubular element, the expander being suitable to radially expand the sleeve to an outer diameter larger than said first inner diameter by moving the expander in axial direction through the sleeve; and c) moving the expander in axial direction through the sleeve thereby radially expanding the tubular element from the first inner diameter to the second inner diameter.

L'invention concerne un procédé de mandrinage d'un élément tubulaire pour le faire passer d'un premier diamètre intérieur à un second diamètre intérieur plus grand. Le procédé consiste à: a) installer un manchon en matériau souple dans l'élément tubulaire; b) installer dans l'élément tubulaire un mandrin approprié pouvant agrandir radialement le manchon et lui conférer un diamètre extérieur supérieur audit premier diamètre intérieur par déplacement du mandrin dans le sens axial à travers le manchon; et c) déplacer le mandrin dans le sens axial à travers le manchon pour ainsi agrandir radialement l'élément tubulaire et le faire passer du premier diamètre intérieur au second diamètre intérieur.
