A method of assembling pipe joints in a pipe string allows the circumferential orientation of a first pipe (13) in the pipe string to be determined relative to a second pipe (13) in the pipe string. Each pipe joint has a coupling member (15) and at least one pin member (13), the pin member (13) being threadingly connected to the coupling member (15) to create the pipe joint (11). Threads (21, 29) are created for the pin member (13) and the coupling member (15) of each joint, and each pin member and coupling member is marked with an alignment mark (35, 37). The threads (21) for each pin member are created so that they are identical to the threads on the other pin members in the pipe string. This is done by gaging the overall rotational capacity of each pin member with a coupling marking gage (43) and adjusting a thread depth as needed.

Procédé de montage de raccord de tube dans une colonne de tubes permettant de déterminer l'orientation de la circonférence d'un premier tube (13) de la colonne de tubes par rapport à un deuxième tube (13) de ladite colonne. Chaque raccord de tube possède un élément d'accouplement (15), au moins une tige (13) accouplée par filetage à l'élément d'accouplement (15), de manière à créer le raccord (11). On crée des filets (21, 29) pour la tige (13) et l'élément d'accouplement (15) de chaque raccord et on pose un repère d'alignement (35, 37) sur chaque tige et chaque élément d'accouplement. On crée les filets (21) de chaque tige, de façon à les rendre identique au filet des autres tiges de la colonne de tubes. Pour ce faire, on étalonne la totalité de la capacité de rotation de chaque tige au moyen d'un gabarit de marquage d'accouplement (43) et on règle la profondeur des filets en fonction des besoins.
