ABSTRACT:
The invention relates to a tubing expansion tool and to a method of expanding tubing. In one embodiment, a tubing expansion tool (10) is disclosed which comprises a body (14) and at least one expansion member (16) radially movably mounted on the body (14) for movement towards an extended configuration describing an expansion diameter for expanding tubing (12) to a predetermined diameter, the expansion member (16) being lockable in the extended configuration. In further embodiments, the expansion member (16) is biased radially inwardly; the expansion member (16) is moveable in response to both an applied mechanical force and an applied fluid pressure force; and the expansion member (16) is pivotably mounted with respect to the body (14).
