Publication number: 20220412486Abstract: In a threaded connection for pipe with intermediate shoulder surfaces provided between two thread steps for functioning as torque shoulders, the compression resistance under repeatedly applied combined loads is improved. The axial distance between the box intermediate shoulder surface 33 and box end shoulder surface 34 of the box 3 before make-up, LB, is larger than the axial distance between the pin intermediate shoulder surface 23 and pin end shoulder surface 24 of the pin 2 before make-up, LP, such that, upon completion of make-up, the pin and box intermediate shoulder surfaces 23 and 33 are in strong pressure contact to function as torque shoulders, while the pin and box end shoulder surfaces 24 and 34 are not in contact or are in light contact.Type: ApplicationFiled: December 22, 2020Publication date: December 29, 2022Inventors: Satoshi MARUTA, Yousuke OKU, Pierre MARTIN, Daly DALY

Patent number: 11493154Abstract: A threaded tubular connection comprises a first tubular component and a second tubular component. The first tubular component includes a female portion defined on an interior surface of the first tubular component. The female portion includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder. The second tubular component includes a male portion defined on an exterior surface of the second tubular component. The male portion is to be inserted into the female portion, and includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder. The second shoulder is to abut the first shoulder once the male portion is connected to the female portion.Type: GrantFiled: December 11, 2015Date of Patent: November 8, 2022Assignees: VALLOUREC OIL AND GAS FRANCE, NIPPON STEEL CORPORATIONInventors: Daly Daly, Alan Ford Fothergill, Sebastien Roger Claude Villert

Patent number: 9605781Abstract: A threaded tubular connection includes a female threaded portion at a first tubular component end and a male threaded portion at a second tubular component end, the female threaded portion including a female thread, at least one female sealing surface on its inner peripheral surface, and at least one female axial abutment surface, the male threaded portion including a male thread, at least one male sealing surface on its outer peripheral surface, at least one axial abutment surface, and a lip disposed between the sealing surface and an axial abutment surface located at a free end of the threaded portion distant from the thread, the male thread being made up into the female thread such that at least one male axial abutment surface is in contact with at least one female axial abutment surface, at least one male sealing surface being in interference contact with at least one corresponding female sealing surface, the portion of the lip between the sealing surface and the axial abutment surface being radially distType: GrantFiled: November 3, 2008Date of Patent: March 28, 2017Assignees: VALLOUREC OIL AND GAS FRANCE, NIPPON STEEL & SUMITOMO METAL CORPORATIONInventors: Sylvain Beigneux, Daly Daly, Bertrand Maillon, Claire Patureau, Eric Verger, Michihiko Iwamoto, Keiichi Nakamura, Masaaki Sugino, Suguru Yamaguchi

Patent number: 9568125Abstract: A threaded joint for steel pipes comprising a pin (1) and a box (2). The pin has a male thread (11) and a lip (12) which comprises (i) a sealing surface (13) and (ii) a nose portion (16) provided with a shoulder surface. The box has a female thread (21), a sealing surface (23) and a shoulder surface. The shoulder surface of the pin comprises two distinct adjacent surfaces, main shoulder (14) in the inner side and sub shoulder (15) in the outer side. Correspondingly, the shoulder surface of the box comprises two distinct adjacent surfaces, main shoulder (24) in the inner side and sub shoulder (25) in the outer side. The main shoulder surfaces of the pin and box are disposed such as to prevent a radially inward deformation of the lip end, and the sub shoulder surfaces of pin and box are disposed such as to limit a radially outward deformation of the lip end.Type: GrantFiled: May 6, 2010Date of Patent: February 14, 2017Assignees: NIPPON STEEL & SUMITOMO METAL CORPORATION, VALLOUREC OIL AND GAS FRANCEInventors: Suguru Yamaguchi, Keiichi Nakamura, Masaaki Sugino, Michihiko Iwamoto, Gabriel Briquet, Claire Patureau, Daly Daly, Bertrand Maillon, Sylvain Beigneux

Publication number: 20110241339Abstract: A threaded connection and a method for producing such a connection. The threaded connection includes a first and a second tubular component. The first component includes a male end provided on its outer peripheral surface with, in succession, a threaded zone, a sealing surface, and a terminal surface finishing in an abutment surface orientated radially with respect to the axis of revolution of the connection. The second component includes a female end provided on its inner peripheral surface with, in succession, a threaded zone, a sealing surface, and a recess finishing in an abutment surface orientated radially with respect to the axis of revolution of the connection. The threaded zone of the male end is made up into the threaded zone of the female end such that the sealing surfaces are in interfering contact, as are the abutment surfaces, the space between the terminal surface and the recess defining a volume at least partially filled with a filling material.Type: ApplicationFiled: December 1, 2009Publication date: October 6, 2011Applicants: VALLOUREC MANNESMANN OOIL & GAS FRANCE, SUMITOMO METAL INDUSTRIES, LTD.Inventors: Eric Verger, Bertrand Maillon, Daly Daly, Sylvain Beigneux
