Abstract: A torque measuring flange is provided for use with a tong arrangement. The torque measuring flange includes a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.

Abstract: A method of coupling a tool to a length of tubular comprises securing the tool in a basket; lowering a tong arrangement having a rotary part and a stationary part, relative to the basket to engage respective locking members of the tong arrangement and the basket, thereby fixing the basket and the tool relative to the stationary part of the tong arrangement; and rotating the length of tubular using the rotary part of the tong arrangement so as to couple the tool to the length of tubular. A torque measuring flange may be associated with the tong arrangement. The torque measuring flange comprises a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.

Abstract: Apparatus for applying torque to a first tubular relative to a second tubular, the apparatus comprising a first tong for gripping the first tubular and a second tong for gripping the second tubular, wherein the first tong is provided with teeth around a peripheral surface thereof, the second tong is provided with at least one pinion, and the pinion meshes with the teeth in such a way that the first tong and the second tong can be rotated relative to one another when the pinion is rotated. The apparatus may include a positioning apparatus for determining the position of the tubular relative to the tong. The positioning apparatus comprising a plunger movably disposed on a base and coupled to a visual indicator. The plunger includes a contact member disposed at one end, whereby contact with the tubular causes the plunger to move along the base and the distance traveled is indicated by the visual indicator. The apparatus may further include a torque measuring flange.
