Abstract
Disclosed is a tubular expansion tool which includes a plurality of stackable piston/slip/spring assemblies that are used to radially expand a liner against well casing along a longitudinal distance 'L.' The pistons are repeatedly stroked a short distance 'S' with the application of hydraulic pressure. As the pistons are stroked, they move a mandrel-expansion die sub assembly in successive steps a distance “S” to perform the tubular expansion over a longer distance “L.”
