Abstract: A liquid cooled thermal heat sink is provided. A plurality of jet orifices provide an exit for pressurised liquid to exit a plenum chamber and impinge on a thermal surface whereby they effect a cooling of the thermal surface, the heated liquid being transferred through an exit channel to dissipate heat away from the thermal surface.

Abstract: A threaded tubular connection for drilling or operating hydrocarbon wells contains a portion of a tubular element with a male end having an axis of revolution and provided with a first threading extending about the axis of revolution, the male end portion being complementary with a portion of a tubular element with a female end having an axis of revolution and provided with a second threading extending about the axis of revolution, the male and female end portions being capable of being connected by makeup, each of the male and female end portions further comprising a sealing surface with a metal-metal interference, wherein the threading and the sealing surfaces of the male and female end portions are coated with a metallic anti-corrosion and anti-galling layer wherein zinc (Zn) is the major element by weight. One of the metallic anti-corrosion and anti-galling layers is coated with a passivation layer and the other is at least partially coated with a lubricant layer.

Abstract: The invention concerns a threaded portion of a tubular element for a threaded tubular connection having an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion. The threading and the first sealing surface are coated with a metallic anti-galling layer wherein zinc (Zn) is the major element by weight, the metallic anti-galling layer being at least partially coated with a lubricant layer comprising a resin and a dry solid lubricant powder dispersed in the resin.

Abstract: The invention concerns a threaded portion of a tubular element for a threaded tubular connection hiving an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion of a tube. The threading and the first sealing surface are coated with a metallic anti-corrosion and anti-galling layer wherein zinc (Zn) is tie major element by weight.

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.
