ASSEMBLY FOR PRODUCING THREADED CONNECTION FOR DRILLING AND OPERATING HYDROCARBON WELLS AND RESULTING THREADED CONNECTION Russian patent published in 2018 - IPC E21B17/42 F16L15/00 F16L15/06 

FIELD: machine building.

SUBSTANCE: assembly for producing a threaded connection, comprising a first and a second tubular component with an axis of rotation, each respectively provided at one of their ends with at least a first and a second continuous threaded zone, respectively produced on the outer or inner circumferential surface of the component depending on whether the threaded end is male or female in type, in the form of a first and a second helix each provided with a first and a second taper generatrix. First threaded zones produced in accordance with the first helix are capable of cooperating together in makeup and the second threaded zones produced in accordance with the second helix are capable of cooperating together in makeup. Each of the threaded zones defines a thread profile, viewed in a longitudinal section passing through the axis of rotation, is provided with load flanks, stabbing flanks, thread crests and thread roots. Each of the profile heights of the threads of the first threaded zones and the profile height of the threads of the second threaded zones are in the range 1 mm to 2.5 mm, and the angle of the load flanks of the first and second threaded zones with the normal to the axis of rotation is in the range 1 to 20 degrees, and the angle of the stabbing flanks of the first and second threaded zones with the normal to the axis of rotation is in the range 3 to 25 degrees.

EFFECT: present invention relates to threaded joints for drilling and/or operating hydrocarbon wells.
