摘要：Apparatus and method for positioning a pipe in a torque device (1) for oilfielduse where the cross sectional dimension of the pipe varies between operations, andwhere at least a first, second and third clamp bodies (22, 24, 26) are movable between apassive retracted position ( 212, 214) and an active extended position (194, 198, 202, 204,206, 208) where the clamp bodies (22, 24, 26) engage with the pipe, wherein at least oneof a first distance (I) or second distance (II) between the retracted position (212) andactive extended position (194, 198, 202) of the first clamping body (22) or the secondclamping body (24), is different from a third distance (III) between the retracted position(214) and the active extended position (204, 206, 208) of the third clamping body (26), andwhere the individual operational speeds of movement of the clamping bodies (22, 24, 26)are set at a ratio where each clamping body (22, 24, 26) at the same time moves a distance(I, II, III) that equals the distance between their point of contact (194, 198, 202, 204, 6, 208)with one of the larger, medium or smaller diameter 20 pipe (186, 188, 190), and theirpoint of contact (194, 198, 202, 204, 206, 208) with another of the larger, medium orsmaller diameter pipe (186, 188, 190).
