摘要： Threaded connection for exploration and production of a hydrocarbon well, said threaded connection includes a pin including an outer pin surface with an external thread, a box including an inner box surface with an internal thread for mating with the external thread during make-up of the threaded connection, and an anti-rotation device to allow relative rotation between the pin and the box in a make-up rotation direction and prevent relative rotation between the pin and the box in an opposite break-out rotation direction. The pin and the box extend along a longitudinal axis. The anti-rotation device can include a first anti-rotation member which is arranged in a first radial recess provided in the outer pin surface or the inner box surface, and a second anti-rotation member provided at the other of the outer pin surface and the inner box surface.

摘要： Threaded joint for pipes consisting of a male member (1) and a female member (2), which are provided on the outer and inner surfaces respectively with two threading portions presenting a lead-in flank β such that 10°≦β≦25°, an abutment surface (9) being present at the end of said male member for abutment to a corresponding annular abutment surface (10) of the female member. The lead-in flanks of the male (1) and the female (2) members, upon make-up and with unloaded joint leave a gap (in the direction parallel to the axis (21) of the joint) varying from 0.01 to 0.12 mm. The internal and external diameters D3 and D4 (of the pipe portion not involved in the coupling with the female member) of said male member, the inner and outer diameters D1 and D2 of the abutment surface of the female member are linked by the relationship: (D22−D12)/(D42−D32)≧0.5.

摘要： A method of testing of a component of a system that includes a pipe of a first length is provided. The method includes the steps of: providing a second length of stock pipe, the second length being greater than the first length; cutting the stock pipe to the first length to produce a cut pipe; inspecting the cut pipe using a non-destructive inspection technique. The non-destructive inspection technique includes the steps of: performing a first non-destructive test on an inner surface of the cut pipe; performing a second non-destructive test on an outer surface of the cut pipe. The method further includes the step of rejecting the cut pipe if the step of inspecting the pipe identifies a flaw.

摘要： 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.
