Method and device for inspecting a threading of a tubular connection used in the oil industry

A device for inspecting a threading of a tubular component for exploration or working of hydrocarbon wells, the device comprising:

• a threaded support that can cooperate by makeup with the threading of the tubular component;
• means for blocking advance of the threaded support during makeup with the threading of the tubular component;
• a longitudinal rail fixed to the means for blocking the advance of the threaded support and extending in a direction belonging to a plane passing through the axis of the threading of the threaded support;
• means for inspecting the threading of the tubular component;
• and
• means for longitudinal guidance to guide the means for inspecting the threading in translation along the longitudinal rail,
• wherein the means for inspecting the threading of the tubular component comprises two arms, each including a first and a second end, the first ends being connected together by a deformable portion that allows an angular displacement between the second ends, the second ends each carrying a contact element, the inspection means further comprising means for determining the displacement.
