An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.
