  • Patent number: 10371308
    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.

  • Patent number: 9919563
    Abstract: A radial tire includes a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The first reinforcers have a diameter between 0.40 mm and 0.70 mm and a density between 70 and 130 threads/dm, and the second and third reinforcers have a diameter between 0.20 mm and 0.50 mm and a density between 120 and 180 threads/dm.

  • Publication number: 20150013873
    Abstract: A radial tyre, which is useable for a passenger vehicle or a van, has a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The multilayer composite laminate allows the tyre's weight and rolling resistance to be reduced without impairing the tyre's cornering stiffness and, therefore, road holding and handling. At the same time, the multilayer composite laminate enables the tyre to have a running endurance that is at least equivalent if not better than that of a conventional tyre.
