Abstract: The invention relates to an assembly comprising: an oil extraction pipe (4) having a thread; and a protector (1) for the thread of the extraction pipe (4), said protector (1) including a body and a thread complementary to that of the extraction pipe (4). The assembly is characterised in that it also comprises an elastomer film (60) affixed to the protector and designed to form a sealed connection between the extraction pipe (4) and the protector (1) when the protector (1) is positioned on the extraction pipe (4).

Abstract: The invention relates to a protector (1, 7) for an oil extraction pipe. The invention comprises: a hollow, substantially frustoconical connecting segment (2) having a proximal end (21), a distal end (22) and a thread (42) complementary to that of the pipe; and a bumper segment (3) having a connecting end (31) in the extension of the connecting segment (2) and a free end (32), said bumper segment including an internal ring (33) extending in the extension of the connecting segment (2) and an external ring (34) extending coaxially from the connecting segment, defining an internal space between the internal (33) and external (34) rings and increasing the outer diameter of the protector (1, 7). The protector (1, 7) is characterized in that all of the walls thereof having a substantially equal thickness, such that the shape is suitable for production by means of injection, and in that it is produced by means of injection.

Abstract: The invention relates to an assembly including: an petroleum extraction pipe (2) having a thread at the ends thereof, and two protectors (1) for the thread of said extraction pipe (2), each of the protectors including a tubular body and a thread that is complementary to said thread of the extraction pipe, wherein said assembly is characterized in that it includes at least one module (3) for containing information relating to at least one property of an extraction pipe (2), said module being removably connected to said extraction pipe (2).
