An assembly producing a threaded connection, including first and second tubular components with an axis of revolution and each respectively including at one end at least a first continuous threaded zone following a first helix on an outer or inner circumferential surface depending on whether the threaded end is male or female in type, and configured to cooperate together upon makeup. The first threaded zones of the ends include a variable width dovetail thread profile, the ends respectively finishing in a terminal surface. At least one of the ends include a lip provided between the threaded zone and the terminal surface, the lip carrying a sealing surface configured to cooperate in a sealing interference fit with a corresponding sealing surface disposed facing the other end when the connection is in the made-up state. The lip is hollowed out by a groove adjoining the threaded zone and the sealing surface.

Assembly for producing a threaded connection for drilling and operating hydrocarbon wells, and resulting threaded connection

A device includes a first sensor for making a radial measurement of a tubular component and a support which can drive the first sensor in a circular trajectory in a predefined plane orthogonal to the principal axis of the component. The support includes a principal body that can be attached to the component by a releasable attachment mechanism and a rotary shaft onto which an arm carrying the first sensor is attached to allow displacement of the first sensor in a circular trajectory inside or about the component. The device further includes a second sensor for measuring an angular position of the first sensor for each of its radial measurements, the radial and angular measurements obtained allowing the profile of the component in the predefined plane to be determined.
