INSPECTION METHOD OF GAUGE FOR A SELF-LOCKING THREADING OF A TUBULAR CONNECTION USED IN THE OIL INDUSTRY.

摘要

The invention concerns a method and a gauge for inspecting a self-locking threading provided close to one end of a tubular component used for the exploration or operation of hydrocarbon wells, said threading having a lead with a constant width and thread root widths which increase in the direction of the distal surface of the tubular component, characterized in that the gauge is suitable to be displaced in the self-locking threading to a locking position, said locking position then being marked and compared with a reference locking position.
