    摘要： A threaded connection design having a double ellipse in the thread root for reducing stress fatigue is illustrated in this disclosure. The root groove includes a first portion comprising a first elliptical surface being part of a first ellipse. The root groove further includes a second portion comprising a second elliptical surface, being part of a second ellipse, and the second elliptical surface being joined tangentially at a first end to the first elliptical surface at a junction point that defines the bottom of the root groove. The second elliptical surface is joined tangentially at a second end to the load flank.

    摘要： 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 within a central section of the joint. When the male members are substantially engaged within the joint, the ring is compressed by the ends of the male members.
