The threaded tubular connection includes a male tubular element including a tapered male threading, and a female tubular element including a tapered female threading that cooperates with the male threading by makeup to produce a rigid mutual connection of the tubular elements with radial interference between radial load transfer zones of the threadings. The male and female threadings each have a load flank extending substantially perpendicularly to an axis of the male and female threadings. The radial load transfer zones are at a radial distance from envelopes of thread roots of the male and female threadings.

Patent number: 7621034Abstract: A tubular joint including a conical male thread and a conical female thread. An annular housing is disposed close to a free end of the female element and is used to house a deformable sealing ring. The sealing ring is in sealed contact with the peripheral surface of the housing and with diminishing threads of the male thread and bears axially against a shoulder that faces the free end, thereby limiting the housing.Type: GrantFiled: August 11, 2003Date of Patent: November 24, 2009Assignees: Vallourec Mannesmann Oil & Gas France, Sumitomo Metal Industries, LtdInventor: Gabriel Roussie

Patent number: 7513534Abstract: A fatigue-resistant threaded element for a threaded tubular connection. A portion of threads of the threaded element have a helical groove opening into the threaded crest. A groove is formed in all or a portion of the threads of one or both end zones, namely the first engaged thread zone and the last engaged thread zone, and it is optionally formed in the threads of the medial thread zone. The groove reduces stiffness of threads carrying a groove in the end zone or zones compared with the stiffness of the threads in the medial thread zone. The threaded tubular connection obtained after making up the threaded element with a mating threaded element is much more resistant to cyclic tensile stress and/or axial compressive stresses and/or flexion stresses.Type: GrantFiled: March 4, 2002Date of Patent: April 7, 2009Assignees: Vallourec Mannesmann Oil & Gas France, Sumitomo Metal Industries, Ltd.Inventors: Thierry Noel, Gabriel Roussie

Patent number: 7475476Abstract: In a threaded connection with tapered male and female threads, an annular housing is provided in the vicinity of the free end of the female element, which housing receives a portion of a deformable sealing ring, which is radially compressed, while a retaining lip of the ring is immobilized in a further annular housing of the female element by a rib on the male element. Such a connection may find particular application for connecting pipes for hydrocarbon wells.Type: GrantFiled: November 28, 2003Date of Patent: January 13, 2009Assignees: Vallourec Mannesmann Oil & Gas France, Sumitomo Metal Industries Ltd.Inventor: Gabriel Roussie

Publication number: 20080264632Abstract: A unit is dedicated to mechanically loading a tubular sample (ET). It comprises at least one packer (P) housed in the sample (ET) at a test zone (ZT), having a longitudinal extension which is greater than that of said test zone (ZT) and comprising i) first pressure means (C1) instructed to cause local variation in the diameter of at least a first portion of the packer (P) so as to apply it against an internal surface of the sample (ET) at the test zone (ZT), ii) second pressure means (C2) charged with exerting a first selected internal pressure over a portion of the internal surface located at a second portion of the packer (P), and/or iii) third pressure means (C3) instructed to cooperate with at least one plug member (B1, B2) attached to the sample at a distance from one end of the packer (P) to define a zone of action (ZA), so as to exert on the sample (ET) a second selected internal pressure at the zone of action (ZA).Type: ApplicationFiled: February 23, 2006Publication date: October 30, 2008Applicant: Vallourec Mannesmann Oil & Gas FranceInventors: Didier David, Thierry Noel, Gabriel Roussie

Patent number: 7334821Abstract: A premium threaded tubular connection including, on at least one threaded element, a distal abutment surface at the free end of a threaded element, and a lip sealing surface at a given distance from the threading. The lip includes an appendix that extends the lip towards its free end beyond the lip sealing surface so that the lip has both high radial stiffness and low axial stiffness. This results in enhanced performance as regards the seal of the threaded connection under pressure and/or under tension, and other advantages of precision of real makeup torque, mechanical strength in axial compression, a shock barrier effect, and tolerance in engaging the threaded elements.Type: GrantFiled: December 3, 2002Date of Patent: February 26, 2008Assignees: Vallourec Mannesmann Oil & Gas France, Sumitomo Metal Industries, Ltd.Inventors: Pierre Dutilleul, Gabriel Roussie

Patent number: 7331614Abstract: A threaded tubular connection includes two elements, male and female, made up one into the other to a given torque in which, prior to making up, at least one thread face under contact pressure has a convexly rounded shape that is continuous over its width with a radius of curvature in the range 2 to 60 mm and is in point contact with the corresponding face of the mating element. Such a threaded connection has an increased resistance to breakout or to overtorquing. In one embodiment, the convexly rounded face is a male or female thread flank and one of the male or female threads includes a groove opening into the thread crest to render flexible either the convexly rounded flank or the corresponding flank. Such a geometry can accommodate variations in contact between the flanks.Type: GrantFiled: February 4, 2002Date of Patent: February 19, 2008Assignees: Vallourec Mannesmann Oil & Gas France, Sumitomo Metal Industries, Ltd.Inventors: Thierry Noel, Gabriel Roussie, Emmanuel Varenne

Publication number: 20080012321Abstract: A method to improve fatigue resistance of a threaded tubular connection. Radial interference between a male and female threading operates between stabbing flanks inclined at about 27° with respect to an axis of the threadings, wherein mutual contacting surfaces are radially spaced from a root of the male threading, which is defined by a concave rounded portion. Thus, micro-cracks caused by friction between these surfaces during relative movements of the male and female threaded elements are not affected by tensile stresses moving along an envelope of the male thread root, improving fatigue resistance of the connection. Such a method may find particular application to hydrocarbon wells connected to offshore platforms.Type: ApplicationFiled: December 2, 2004Publication date: January 17, 2008Applicants: Vallourec Mannesmann Oil &Gas France, Sumitomo Metal Industries, Ltd.Inventor: Gabriel Roussie
