THREADED TUBULAR CONNECTION WHICH IS RESISTANT TO BENDING STRESSES

摘要

A threaded tubular connection comprises a male tubular element comprising a male threaded portion and a female tubular element comprising a female threaded portion which cooperates by screwing with the male threaded portion. In accordance with the invention, the threaded connection comprises at least one transfer zone which can transfer bending loads between said elements and which is axially spaced from said threaded portions, in which the male and female elements have an undulating surface and a smooth surface facing each other, the undulating surface (5) defining a series of rounded annular ribs (7) which come into contact with the smooth surface with a radial interference fit. Application to production strings for hydrocarbon wells.
