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

摘要

The invention concerns a device for inspecting a threading (fc) of a tubular component for the exploration or working of hydrocarbon wells, the device comprising a threaded support (14) which can cooperate by makeup with the threading (fc) of the tubular component, means (12, fs) for blocking the advance of the threaded support (14) during makeup with the threading (fc) of the tubular component, a longitudinal rail (2) fixed to the means (12, fs) for blocking the advance of the threaded support (14) and extending in a direction belonging to a plane passing through the axis of the threading of the treaded support (14), means (9) for inspecting the treading of the tubular component (fc), and means (4) for longitudinal guidance in order to guide the means (9) for inspecting the treading in translation along the longitudinal rail (2). The invention also concerns methods using the device.
