20100102553 | THREADED TUBULAR CONNECTION WHICH IS LEAK-PROOF UNDER INTERNAL AND EXTERNAL SUCCESSIVE PRESSURE LOADS - A threaded tubular connection that is leak-proof for internal and external successive pressure loads including a male element and a female element. At least one of the male or female elements includes a lip between the threading and the free end of the element. The lip includes a first zone with a peripheral surface turned towards the other element on which a first metallic sealing surface is disposed that can be radially interference fitted against a corresponding second metallic sealing surface disposed on the other element. The lip includes a second zone located axially between the first zone and the corresponding threading. The radial stiffness of the second zone is less than that of the first zone and that of a third zone adjacent to the second zone in the direction of the threading, and the second zone can be radially deformed by a pressure exerted thereon. | 04-29-2010 |
20100301603 | THREADED CONNECTION COMPRISING AT LEAST ONE THREADED ELEMENT WITH AN END LIP FOR A METAL TUBE - 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 distant from a corresponding surface of the other threaded portion, at least one leak channel being provided in one of the threaded portions to place the chamber formed between the lip and the corresponding surface of the other threaded portion in communication with the interior of the connection. | 12-02-2010 |
20110266794 | SEALED TUBULAR CONNECTION USED IN THE OIL INDUSTRY - The invention concerns a sealed threaded connection comprising a first and a second tubular component, each being provided with a respective male end ( | 11-03-2011 |
