The invention relates to a temporary protector (1) for one end of a tubular joint component used for the drilling or exploitation of hydrocarbon wells, said end having at least one screw thread and at least one free terminal portion, and said component comprising a body downstream of the threaded end. The protector (1) comprises: a sleeve (2) intended to be mounted on the end of the component and shaped to protect the free terminal portion and the screw thread at the end of the component, said sleeve (2) having a screw thread (24) intended to engage with the screw thread at the end of the component and extending axially over a distance less than or equal to the axial distance of the screw tread at the end of the component; and a peripheral sealing device (4) which is mounted hermetically on the sleeve (2) and which can be placed in contact with a surface of the component located downstream of the screw thread at the end of the component, such as to provide the downstream sealing of the screw thread, said sealing device (4) and sleeve (2) being arranged such that, when the screw thread (24) of the sleeve (2) engages with the screw thread at the end of the tubular joint component, during installation of the protector on the tubular component, at least part of the sealing device (4) which is intended to come into contact with the surface of the component is positioned axially downstream of the screw thread at the end of the component. |
