摘要： An assembly including two symmetrically-disposed expandable threaded tubular joints. The joints including a male tubular element at one end of a tube and equipped with a male thread, a first annular lip having a first axially abutting surface, a first inner surface and a first outer surface, and a second abutting surface; and a female tubular element equipped with a female thread, a second annular lip having a third abutting surface, a second outer surface and a second inner surface, and a third inner surface and a fourth axially abutting surface which, together with the second outer surface, defines an annular housing homologous to the corresponding first lip. The two female tubular elements form two opposing ends of a female/female-type sleeve.

摘要： To produce a sealing contact between male and female threaded elements, a contact zone is provided, located between male and female threading portions separated from each other in an axial direction. The male and female elements have respective cylindrical portions that extend over the entire length of the contact zone. After expansion, a sealing contact is established between surfaces in two annular areas by a radial interference fit.
摘要翻译：为了在阳和螺纹元件之间产生密封接触，提供接触区，位于在轴向方向上彼此分离的阳和阴螺纹部分之间。阳元件和阴元件具有在接触区域的整个长度上延伸的各自的圆柱形部分。在膨胀之后，通过径向干涉配合在两个环形区域中的表面之间建立密封接触。
