The upper portion is formed by a thread bevel which transitions into a first rounded area and the lower portion is formed by a second rounded area.

    Abstract: A threaded tubular joint comprising male and female members is provided. The ends of the male members comprise an upper portion and a lower portion located between an upper threaded portion and an inner surface of each of the male ends. The upper portion is formed by a thread bevel which transitions into a first rounded area and the lower portion is formed by a second rounded area. A reversibly deformable ring may be housed in about the center of the joint. When the male members are substantially engaged within the joint, the ring is compressed by the ends of the male members. This configuration provides geometric continuity within the inner surface of the joint, and the corrosion protection barrier of the inner lining of the tube.
