20100167968 | LUBRICATING COMPOSITION WITH AN ADAPTABLE COEFFICIENT OF FRICTION, FOR A THREADED ELEMENT OF A COMPONENT OF A TUBULAR THREADED JOINT - A thin adhesive lubricating composition that can cover at least one thread and a screwing abutment of a threaded element of a component of a tubular threaded joint. The screwing abutment can bear against another abutment of another component of the tubular threaded joint in a terminal make up phase. The lubricating composition includes a matrix in which there is dispersed at least one braking additive selected to impart thereto, in addition to lubrication, a coefficient of friction to make it possible to obtain a torque on shoulder resistance value at least equal to a threshold value. | 07-01-2010 |
20100201119 | TUBULAR THREADED MEMBER WITH DRY PROTECTION COATING - A tubular threaded element including a dry protective coating. The coating includes a solid matrix adhering to the substrate in which there are dispersed particles of at least one solid lubricant belonging to one and the same class. The solid matrix is lubricating and has a rheological behaviour of plastic or viscoplastic type. The coating protects the threadings of the threaded elements, used for example in hydrocarbon wells, from corrosion and galling. | 08-12-2010 |
20110285124 | LUBRICATION COMPOSITION WITH AN ADAPTABLE COEFFICIENT OF FRICTION, FOR A THREADED ELEMENT OF A THREADED TUBULAR CONNECTION COMPONENT - A film-forming lubrication composition for make-up of threaded connections, intended to cover at least one threading (FE, FI) and a make-up abutment (BVM, BVF) of a threaded element (EM, EF) of a component (T | 11-24-2011 |
20120169048 | GALLING-RESISTANT THREADED TUBULAR COMPONENT AND PROCESS FOR COATING SAID COMPONENT - A galling-resistant threaded tubular component for drilling or operating hydrocarbon wells includes at one of its ends a threaded zone produced on its external or internal peripheral surface depending on whether the threaded end is male or female in type, with at least one portion of the threaded zone being coated with a dry film with a crystalline structure with a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals, and a process for coating such a component using a dry mineral film with a crystalline structure having a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals. | 07-05-2012 |

20140238661 | THREADED TUBULAR COMPONENT AND RESULTING CONNECTION - A threaded tubular component configured for drilling or working hydrocarbon wells, the tubular component including, at one of its ends, a threaded zone formed on its external or internal peripheral surface depending on whether the threaded end is male or female in type. The end portion is at least partially coated with a dry film, including a thermoplastic or thermoset matrix including microcapsules filled with compounds in liquid form. | 08-28-2014 |
20140308455 | METHOD FOR FINISHING A TUBULAR THREADED MEMBER WITH A DRY PROTECTION COATING - A tubular threaded element including a dry protective coating. The coating includes a solid matrix adhering to the substrate in which there are dispersed particles of at least one solid lubricant belonging to one and the same class. The solid matrix is lubricating and has a rheological behaviour of plastic or viscoplastic type. The coating protects the threadings of the threaded elements, used for example in hydrocarbon wells, from corrosion and galling. | 10-16-2014 |
