Abstract

See full text

A clamp assembly is disclosed for breaking a severable connection in a pressurised flowline of an oil or gas well. First and second clamp members have first and second interconnected and clamp segments which are pivotally moveable to close around a conduit. First and second guide rods with parallel axes connect the respective first and second clamp segments of the first and second clamp members. A drive mechanism drives axial movement of the first and second clamp members relative to each other. The first and second clamp members engage first and second conduits on opposite sides of the severable connection. Each clamp segment has an inner surface comprising a recess adapted to receive a load shoulder on the conduits.
