  • Patent number: 10641081
    Abstract: A device and method for retaining a sacrificial wear sleeve on the exterior of an in-pipe device such as an electronics package or probe. In one embodiment, the retention mechanism comprises a ring having a protuberance or lip extending parallel to and against the end of the sleeve, thus pressing the end of the sleeve against the external surface of the device. This has the advantage, in situations where fluids are flowing through the pipe and around the device, of reducing the risk of fluids moving beneath the sleeve and damaging it and/or the underlying device external surface. In another embodiment, the retention mechanism is of unitary construction with the device itself and comprises a protuberance or lip extending parallel to and against the end of the sleeve, thus pressing the end of the sleeve against the external surface of the device.

  • Patent number: 8534712
    Abstract: A threaded joint for pipes includes a pin member and a box member, the pin member having an external thread configured to correspond to an internal thread of the box member, a thread form of the internal and external threads having generally dovetail-shaped profile with stab flanks and load flanks and flat roots and crests, wherein the internal threads are increasing in width in one direction on the box and the external threads are increasing in width in the other direction on the pin, so the roots, crests, and flanks of the threads move together and form seals that resist the flow of fluids between the seals.

  • Patent number: 8517702
    Abstract: A rotary compressor is provided, in which an inner diameter of a connection hole connected to a vane chamber and an outer diameter of a connection tube inserted into the connection hole are designated so that the connection tube can closely be adhered to the connection hole, thereby preventing a refrigerant from being leaked out between the connection hole and the connection tube so as to allow a fast and accurate mode switching of the vane, resulting in improvement of the performance of the compressor and prevention of noise caused by vibration of the vane.

  • Publication number: 20130207378
    Abstract: A ball joint (1) for a pipe connection includes shell parts (3, 4) surrounding one another in a sealing manner, which each define a respective longitudinal centre line and which are rotatable in relation to one another between an aligned position, in which the longitudinal centre lines coincide, and a rotated position, in which the longitudinal centre lines form an angle with one another which differs from zero. The shell parts together enclose an axial passage which extends between the connecting pieces or sleeves (20), (21) of the shell parts (3, 4) facing away from one another. In the outermost shell part (4), a lining (13) is provided, of which the inner lining surface (14) has a curvature corresponding to the curvature of the outer surface (5) of the inner shell part (3).

  • Patent number: 8443898
    Abstract: A wellhead safety device can include a tubular with outer surface portions having different diameters. A first seal groove can be disposed on a first outer diameter. A locking groove can be formed in a first outer surface portion, and can have sloping sides that taper to a center for receiving locking pins of a tubing head. A sloping guide can extend from a first end towards a central bore of the wellhead safety device. A second seal groove can be disposed on a second outer surface portion for containing a second seal. A guide shoulder can be formed on a second end, and can taper from the second outer surface portion to the central bore. A J-latch can be formed in the first end. A landing shoulder can stop the wellhead safety device from slipping into wellbores.

  • Patent number: 8397766
    Abstract: A pipeline has a first pipe and a second pipe welded together by a weld seam, wherein the first and second pipes each have an inner side with a lining section of plastic material for protecting an inner side of the pipeline. The lining sections end at a spacing from the weld seam. The lining section of the first pipe abuts the lining section of the second pipe such that by an undercut provided on at least one of the lining sections a fill space is formed in a circumferential direction of the pipeline.

  • Patent number: 8322754
    Abstract: Coating systems which provide corrosion resistance and, optionally, lubrication, for threaded connections are disclosed. The compositions comprise a first coating composition comprising polymer matrices of polyimides or epoxies which are modified with small amounts of a fluorine containing polymer. Also present in the coating compositions are corrosion inhibiting agents and inorganic particles having a mean diameter of between approximately 10 nm and 10 ?m. Solid lubricants, which may include at least one of PTFE, HDPE, Graphite, and MoS2, are optionally added to provide the first coating with a low coefficient of friction. The coating systems may further comprise a second coating composition, comprising a solid lubricant dispersed within an epoxy resin and a solvent. The first and second coating compositions are deposited on at least a portion of at least one of the pin and box members of the threaded connections.
