  • Patent number: 9080711
    Abstract: 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.

  • Patent number: 6933264
    Abstract: The invention concerns a threaded component for a seizure-resistant tubular threaded joint wherein a lubricating substance is deposited in a thin film on at least the surface of the threads of the threading, said surface being treated to adsorb said lubricating substance. The lubricating substance consists of a homogeneous mixture of a) a thickening agent; b) a set of extreme-pressure additives physically and chemically compatible with the thickening agent and comprising at least an extreme-pressure additive with chemical action called chemical EP additive and capable of being used at Hertz pressures not less than 1000 Mpa's; c) an oil. The proportions of the constituents of the lubricating substance are selected such that said lubricating substance has a consistency capable of ensuring a self-induced and film-forming lubricating process. The invention also concerns a method for producing the thin film.
