Abstract: A tubular connection includes a pin member having external wedge threads configured to engage a box member having corresponding internal wedge threads, and a solid lubricant coating applied on at least one of the internal and external wedge threads wherein the solid lubricant coating comprises a first uniform layer of a dry corrosion inhibiting coating made of an epoxy resin containing particles of zinc and a second uniform layer of a dry lubricant coating covering the first uniform layer.

Abstract: A threaded connection includes a pin member comprising a first pin step and a second pin step, and pin wedge threads disposed on each of the first and second pin steps and a box member comprising a first box step and a second box step, and box wedge threads disposed on each of the first and second box steps, wherein an axial separation of the first and second pin steps differs from an axial separation of the first and second box steps.

Abstract: A threaded connection including a pin member and a box member, and methods for manufacturing and forming said threaded connection. The pin member has a pin thread with a pin thread crest, a pin thread root, a pin load flank, and a pin stab flank. The box member has a box thread with a box thread crest, a box thread root, a box load flank, and a box stab flank. At least one of the pin thread crest, the pin load flank, the pin stab flank, the box thread crest, the box load flank, and the box stab flank has at least one perturbation formed thereon. Upon a selected make-up of the pin member with the box member, a reduced clearance gap exists between the pin thread and the box thread at the at least one perturbation.

Abstract: A threaded pipe connection including a pin member having an external thread increasing in width in one direction, the external thread including load and stab flanks, a box member having an internal thread increasing in width in the other direction so that complementary internal and external threads move into engagement upon make-up of the connection, the internal thread comprising load and stab flanks, a positive stop torque shoulder, and wherein the width of the internal thread and external thread are selected to provide a selected clearance at least between the internal load and stab flanks and the external load and stab flanks upon initial engagement of the positive stop torque shoulder is disclosed.

Abstract: A threaded connection includes a pin member providing a single external thread comprising a first external portion and a second external portion, a box member providing a single internal thread comprising a first internal portion and a second internal portion, and a radial metal-to-metal seal to seal between the pin member and the box member, wherein the first and second internal portions threadably correspond with the first and second external portions, and wherein the first internal and external portions are characterized by a first wedge ratio and the second internal and external portions are characterized by a second wedge ratio, wherein the first wedge ratio is less than the second wedge ratio.

Abstract: A tubular connection is provided with a first thread on a first step having an initial makeup location and a second thread on a second step, the second thread being a wedge thread and having a selected clearance on stab and load flanks at the initial makeup location of the first thread.

Abstract: A threaded tubular connection has a box member including an internal thread, a pin member including an external thread engageable with the internal thread of the box member, and a protruding sealing surface disposed in the box member such that the pin member flexes radially inward upon passing the protruding sealing surface during make-up. The threaded tubular connection also has a recessed seal cavity disposed in the box member and a reverse angle shoulder at the pin nose that forces the pin member to flex radially outward into the recessed seal cavity of the box member upon final make-up. A method of forming a double flex seal for a tubular connection includes engaging an internal thread of a pin member with an external thread of a box member and flexing a pin nose of the pin member radially inward by passing the pin nose over a protruding sealing surface of the box member during make-up.
