Abstract: A tubing expansion device (10) includes a fixed expansion member (14) for expanding the tubing by inducing hoop stress when the device is moved down the inside of the tubing. The device also includes a number of roller expanders (16, fig 2) which expand the tubing (12) by compressive stress.

Abstract: There is disclosed a tubing expansion device and a method of expanding tubing. In one embodiment, an expansion device (10) is disclosed which comprises at least one expansion member (14) adapted to expand a tubing (12) by inducing a hoop stress in the tubing (12), and at least one further expansion member (16) adapted to expand the tubing (12) by inducing a compressive yield of the tubing (12); and a method of expanding tubing (12) comprising the steps of expanding the tubing (12) at least in part by inducing a hoop stress in the tubing (12), and expanding the tubing (12) at least in part by inducing a compressive yield of the tubing (12).
