  • Method for assessing the quality of the coupling of two tubular components
    Patent number: 12000750
    Abstract: A method for coupling a first tubular component including a threaded portion with a second tubular component including a threaded portion, which includes: engaging the first tubular component on the second tubular component; rotating the first tubular component relative to the second tubular component in order to screw the threaded portions together; obtaining a set of points constituting a curve that represents the torque applied during the screwing of the first tubular component until an end position as a function of the number of turns performed by the first tubular component relative to the second tubular component; comparing parameters of the curve obtained with one or more reference curve(s) of a database in which each reference curve is associated with an assessment of the quality of the coupling; and assessing the quality of the coupling according to the step of comparing the curve.
