  • Threaded connections with high and low friction coatings
    Patent number: 8052173
    Abstract: A threaded metallic joint has the thread surface of pin (100) and box (200) covered with a coating comprising a first layer (24) laid on the overall surface of the pin member (100), and a second layer (25) laid on part of the surfaces of either one of the pin or box members. In a first aspect, the coating comprises a first layer with high friction and anti-seize properties laid on the overall surface of the pin member (100), and a second layer (25) with low friction properties laid on specific parts of the surfaces of either one of the pin or box members. Preferably the specific surfaces are those which are in reciprocal radial contact during make-up until pin and box reach the point where shoulders (9, 10) abut. The second layer may contain polytetrafluoroethylene (PTFE). In a second aspect the first layer with a high friction and anti-seize properties laid on the overall surface of the box member (200).
