METHOD AND CALIBER FOR MONITORING A AUTOBLOATING TUBULAR JOINT THREAD USED IN THE PETROLEUM INDUSTRY

摘要

The invention relates to a method and a gauge for controlling a self-locking thread made in the vicinity of one end of a tubular component used in the exploration or exploitation of the hydrocarbon wells, said thread having a no constant width as well as increasing bottom widths of thread towards the distal surface of the tubular component, characterized in that the gauge is able to be moved in the self-locking thread to a locking position, said locking position being subsequently identified and then compared to a reference blocking position.
