<p>A device for marking pipes, including tools and equipment incorporated in a pipe string, which is used in a well, particularly in connection with the recovery of hydrocarbons, wherein an electronic tag (1, 2) is placed in a mounting hole (9) of a pipe wall (10), and is protected against the surroundings by means of a magnetic non-conductive material, for example a synthetic material. The electronic tag (1, 2) is arranged in a hole or a recess (5, 14) in a support (3, 13), which is made of a magnetic non-conductive material, and which is arranged to be secured in the mounting hole (9). The support (3, 13) is provided with at least one channel (6), which is arranged to establish fluid communication between the first and exposed end surface (7) of the support (3, 13) and its second end surface (8) at the bottom of the mounting hole (9).</p> |
