  • Patent number: 12000216
    Abstract: A pipe assembly has a hollow inner member nested within a hollow outer member. A series of pipe assemblies are connected end-to-end to form a dual-member drill string useful in horizontal directional drilling operations. The drill string has mutually exclusive first and second fluid paths. Fluid seals, interposed between adjacent inner members of the string, isolate the first fluid path from the second fluid path. Compressed air is delivered into the first fluid path from above ground level, and routed to an underground boring tool. The expelled air and spoils are returned to above ground level by way of the second fluid path. One or more baffle elements are supported on the drill string adjacent the boring tool. The baffle elements are configured to prevent compressed air and spoils from flowing between the walls of the borehole and the drill string.

  • Patent number: 11959346
    Abstract: A method for offshore dual-drive core drilling with three layers of casings under surge compensation is provided. According to the method, a drilling vessel is located at set latitude and longitude coordinates by a dynamic positioning system; drill pipes are stabilized by a seabed template; torques and drilling pressures can be transmitted during drilling of the casings by means of surge compensation of the casings at a wellhead; during drilling for sampling, the surge compensation can compensate to a certain extent for a change in water depth caused by rising or falling tides, or surge, thereby preventing the casings from colliding with equipment and ensuring the safety of wellhead operation; and the drilling of three layers of casings is achieved by means of dual driver heads to effectively protect a wellbore wall, such that high core-drilling rate and good core-drilling quality are achieved during drilling for sampling.

  • Patent number: 11077486
    Abstract: An interchangeable die comprises a die head, on which a die feature is formed, and a die shank extending in an axial direction from the die head. The die shank includes a first axial shank section, which is adjacent to the die head, and a second axial shank section, which is arranged on the opposite axial side of the first axial shank section from the die head. The first axial shank section has a first diameter and the second axial shank section has a second diameter smaller than the first diameter. The die shank is introducible into a shank receptacle of a die receiving section of a joining tool. A fastening contour for fastening the interchangeable die to the joining tool is formed on the interchangeable die. The fastening contour is configured such that a plug-and-turn connection is establishable between the interchangeable die and the joining tool.

  • Patent number: 10787950
    Abstract: A processing system 100 includes a heat insulating pipe 12, a temperature measuring device 19, and a control device 20. The heat insulating pipe 12 has an inner pipe and an outer pipe. An airtight space is formed between the inner pipe and the outer pipe. A fluid having a temperature lower than that of an indoor space in which the heat insulating pipe 12 is placed is flown within the inner pipe. The temperature measuring device 19 measures a temperature of a surface of the heat insulating pipe 12. The control device 20 is controls a pressure within the airtight space by controlling an exhaust device 16 configured to exhaust a gas within the airtight space based on the temperature of the surface of the heat insulating pipe 12 and a dew-point temperature calculated from a humidity and the temperature of the indoor space.
