摘要： A threaded connection for a conduit includes a pin member and a box member. The pin member includes a pin thread having a pin thread crest, a pin thread root, a pin load flank oriented at a pin load flank angle, and a pin stab flank oriented at a pin stab flank angle. The box member includes a box thread having a box thread crest, a box thread root, a box load flank oriented at a box load flank angle, and a box stab flank oriented at a box stab flank angle. At least one of the pin load flank angle, the pin stab flank angle, the box load flank angle, and the box stab flank angle varies over at least part of the threaded connection.

摘要： A method for making-up a wedge thread connection comprising a pin member and a box member includes applying a pipe dope to at least one of the pin member and the box member, wherein the pin member and the box member comprise corresponding wedge threads, reducing the viscosity of the pipe dope at least temporarily, and rotating the pin member relative to the box member to make-up the wedge thread connection, wherein the rotation occurs while the viscosity of the pipe dope is at least temporarily reduced. A collar to be used with a tong assembly in making-up a threaded connection between a pin member and a box member includes at least one power unit configured to temporarily reduce the viscosity of pipe dope applied to at least one of the pin member and the box member, and an inner surface having a selected diameter to correspond to an outer diameter of at least one of the pin member and the box member.

摘要： A threaded connection having wedge threads, and a method of manufacturing said threaded connection. The threaded connection includes a pin member (101) and a box member (102) having a pin thread (106) and a box thread (107), respectively. The pin thread has a pin thread crest (221), a pin thread root (291), a pin load flank (226), and a pin stab flank (231). The pin thread (106) includes at least a first step (401), a mid-step (402), and a second step (403) formed sequentially thereon. The box thread (107) has a box thread crest (292), a box thread root (222), a box load flank (225), and a box stab flank (232). The box thread includes at least a first step, a mid-step, and a second step formed sequentially thereon. The steps on the box thread correspond generally in axial position with the steps on the pin thread. The first step (401) has a first wedge ratio, the mid-step (402) has a transition wedge ratio, and the second step (403) has a second wedge ratio. The thread leads are substantially constant within each of the steps. The connection is designed such that, at make-up of the pin member with the box member, a clearance exists between at least one of the corresponding load flanks and the corresponding stab flanks on at least one of the first step, the mid-step, and the second step.

摘要： A tool (200) for radially expanding casing (217) having a tool body that includes a proximal end, a distal end and an outer surface. The tool includes at least one hydraulic channel (303) disposed axially. The at least one channel transmits hydraulic pressure from behind the expansion tool forward in the direction of travel of the expansion tool.
