Pipe connection for exploration and production of a hydrocarbon well, said pipe connection comprising a primary pipe member having an axially extending primary alignment sleeve and one of a second protrusion and a second slot, a secondary pipe member comprising an axially extending secondary alignment sleeve and one of a second protrusion and a second slot, and a locking ring configured to engage the primary pipe member and the secondary pipe member.

Pipe connection for exploration and production of a hydrocarbon well

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.

Threaded connection for exploration and production of a hydrocarbon well

Threaded connection for exploration and production of a hydrocarbon well, said threaded connection including a pin including an outer pin surface provided with an external thread, a box including an inner box surface provided with an internal thread for mating with the external thread during rotational 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, wherein the pin and the box extend along a longitudinal axis, the anti-rotation device includes a releasable mounted first anti-rotation member which is arranged in a first radial recess provided in one of the outer pin surface and the inner box surface, and a second anti-rotation member provided at the other of the outer pin surface and the inner box surface.

Oil well pipe component comprising a threaded portion, at least part whereof is coated with a layer of a corrosion-inhibiting material, that has been applied to at least the part of the threaded portion of the oil well pipe component by means of a method comprising a cataphoresis step from an aqueous bath, said method comprising

Threaded joint for an oil well pipe

A threaded joint for joining tubes used especially in the field of OCTG (Oil Country Tubular Goods), such as pipes in gas or oil production and/or casings when drilling wells can include a pin and a coupling, or box, having an end surface not facing against any surface of the pin when the joint is made-up. Following make-up of the joint, first sealing surfaces of the pin and box mate to form an internal metal-to-metal seal, and second sealing surfaces of the pin and box mate to form an external metal-to-metal seal, where the internal and external seals are defined by contact between one toroidal surface and one frusto-conical surface.

Oil well pipe component comprising a threaded portion, at least part whereof is coated with a layer of a corrosion-inhibiting material, that has been applied to at least the part of the threaded portion of the oil well pipe component by means of a method comprising a cataphoresis step from an aqueous bath, said method comprising&#x2014;providing the oil well pipe component comprising a threaded portion; &#x2014;immersing at least part of the threaded portion of the pipe component in a cataphoresis bath comprising water and suspended particles of corrosion-inhibiting material, and provided with an anode and a cathode means, the pipe component being connected to the cathode means; &#x2014;inducing a current through the bath, in order to provide the corrosion-inhibiting material with a positive charge; &#x2014;depositing a layer of the positively charged corrosion-inhibiting material onto the pipe component; and&#x2014;removing the immersed part of the pipe component with the layer of corrosion-inhibiting material from the cataphoresis bath and allowing the corrosion-inhibiting material to set.

Thin-walled pipe joints can include a first pipe and a second pipe. The first pipe includes a hollow pin member positioned at about an end of the first pipe. The second pipe includes a hollow box member positioned at about an end of the second pipe. The hollow box member is further configured to at least partially surround the pin member of the first pipe. The joint also includes a first ring placed adjacent an end of the hollow pin member and a second ring engaged with the box member. The second ring substantially axially abuts against the first ring and the first ring substantially axially abuts the box member. The second ring further generally extends from the first ring in a direction opposite to the end of the pin member adjacent to the box member.

Thin-walled pipe joint

A threaded connection includes a first pipe having an internal liner and a first pin end on a distal end thereof, the first pin end comprising a first annular seal permanently affixed therein, a second pipe having an internal liner and a second pin end on a distal end thereof, the second pin end comprising a second annular seal permanently affixed therein, a coupling having a first and second box end. The first pin end and the first box end, and the second pin end and the second box end are threadedly are threadedly engaged and a mating surface of the first annular seal is configured to contact a mating surface of the second annular seal and provide a continuous internal seal along an axial length of the threaded connection.

Internally lined pipe connections and related methods of makeup

A threaded joint includes a first seal ring having a tapered shape in a cross section on an axial plane, this ring having an L-shaped metal reinforcement ring embedded in it. The threaded joint can also include a second seal ring positioned more internal to the first seal ring and located in a housing between the end of a threaded section and the nose of the box. The second seal ring has a first base, a second base axially opposite to the first base, and protruding annular ribs either on the external surface or on an internal surface.
