Abstract: A threaded tubular connection which includes a pin member and a mating box member. The pin member has pin threads with stab flanks and load flanks and thread crests and thread roots which are adapted to be made-up with a mating box member having a complimentary thread structure. The threads of the pin member are intentionally made asymmetric to those of the box.

IPC: E21B17/042

Abstract: Provided is a threaded pipe having a pin member connecting to a box member. The pin member contains wedge-shaped pin threads that extends in a helical direction around the outside surface of its pipe end. The pin member is tapered to result in an increasing diameter of the pin threads away from the front end of its pipe. The box member contains a wedge-shaped box thread that stretches in a helical direction around the inside surface of its pipe end. The box member is tapered to result in a decreasing diameter of the box threads away from the front end of its pipe. The pin crest of the pin member increases in width along the pin thread and the box root of the box thread decreases in width along the box thread. When assembled together, the pin thread crest increases in width at a different rate than the box thread root increase in width.

Abstract: The invention relates to a tubular threaded joint for use in the oil and gas industry. A tubular threaded joint comprising a first tubular member (1) having a pin (100) and a second tubular member (2) having a box (200), wherein the pin is an end portion of the first tubular member and comprises on its radially outward-facing surface a male threaded zone comprising a tapered male thread (150). The box is an end portion of the second tubular member and comprises on its radially inward-facing surface a female threaded zone comprising a tapered female thread (250). The male thread and female thread are configured to engage with each other when the joint is in a made-up state. The male thread and female thread are each trapezoidal and comprise a crest, a root, a load flank, and a stabbing flank. On both of the male thread and the female thread at least one of the load flank and the stabbing flank is negatively inclined. A first portion of the male thread extending from an end thereof has a first taper relative to a longitudinal axis of the first member. A first portion of the female thread extending from an end thereof has a second taper relative to a longitudinal axis of the second member, the first portion of the male thread and the first portion of the female thread are configured to engage with each other when the joint is in the made-up state. The second taper is different from the first taper such that the threads converge toward an end of the threads in the made-up state.

Abstract: A method of making-up tubular string components can include inputting to an image processor image data output from at least one camera (28), the image processor in response detecting positions of a tubular (14) and a mark (30) on another tubular (20), threading the tubulars with each other while inputting position data from the image processor to a controller, and the controller terminating the threading in response to the position of the mark relative to the position of the first tubular being within a predetermined range. Another method of making-up tubular string components can include, in response to inputting image data to an image processor, the image processor detecting longitudinal positions of two tubulars, threading the tubulars with each other, and a controller terminating the threading in response to the longitudinal position of one tubular relative to the longitudinal position of the other tubular being within a predetermined range.
