This paper covers research funded by the API Production Research Advisory Committee (PRAC) on leak resistance of API 8-round connectors. It details the sensitivity of leak resistance to variations in makeup turns, pipe diameter, grade, and applied tension. Findings show that the leak resistance of the connector relative to pipe-body ratings increases with the number of makeup turns and decreases as diameter and yield strength increase. Finally tension is found to lower leak resistance in a manner that renders hydrotesting insufficient for defining leak resistance in typical service conditions.
