摘要

"The system expander to expand radially, a tubular element, and method of expanding radially a tubular element using the system expander.A system expander to expand radially, a tubular element having a non expanded portion a first internal diameter.The system expander including a movable between a radially retracted mode expander and a radially expanded.The expander is operable to expand the tubular element of said first internal diameter to a second internal diameter larger than the first internal diameter by the movement of the expanSOR method radially retracted to its radially expanded.Where the expander comprises a contact section of a diameter larger than the internal diameter when the mentioned first in the mode expander is radially retracted.And where that section of contact is arranged to prevent axial movement of the expander through the tubular element portion is not expanded when the expander is in the radially retracted.
