Abstract:
1. A method of making up a tubular connection between a first and second tubular segment, each of said segments comprising an externally threaded male member at one end and an internally threaded female member at the other end, said method comprising: inserting the male member of the first segment into the female member of the second segment; applying a primary torque component to the first segment to engage the external threads of the first segment with the internal threads of the second segment and to advance the male member of the first segment into the female member of the second segment; monitoring the primary torque component applied to the first segment; generating an impulse energy component superimposed on the primary torque component when a predetermined onset threshold has been reached; and discontinuing application of one or both of the primary torque and impulse energy components when a predetermined maximum threshold has been reached.
