Abstract
An apparatus includes a first housing portion comprising a first adjustable gripping system moveable between an engaged position that grips a cylindrical outer surface of a first tubular structure having a first diameter and a disengaged position that permits relative movement of the first housing portion and the first tubular structure. The apparatus also includes a second housing portion fixed relative to the first housing portion so that rotation of the first housing portion results in rotation of the second housing portion. The second housing portion includes a second gripping system to securely grip a cylindrical outer surface of a second tubular structure that is threadably attached to the first tubular structure and has a second diameter different than the first diameter. Methods of breaking tubing hanger connections are also disclosed.
