CA 2451263

A method and apparatus for connecting threaded members while ensuring that a proper connection is made. In one embodiment, the applied torque and/or rotation are measured at regular intervals throughout a pipe connection makeup. When a shoulder contact is detected, a predetermined torque value and/or rotation value is added to the measured torque and/or rotation values, respectively, at shoulder contact and rotation continued until this calculated value(s) is reached.

On présente une méthode et un dispositif pour connecter des éléments filetés, tout en assurant une bonne connexion. Dans un mode de réalisation, le couple et/ou la rotation appliqués sont mesurés à des intervalles réguliers à travers le raccord de tuyauterie. Lorsqu'un contact d'épaulement est détecté, une valeur de couple et/ou une valeur de rotation prédéterminée est ajoutée respectivement à la valeur de couple et/ou de rotation mesurée, au contact d'épaulement, et la rotation est poursuivie jusqu'à ce que cette valeur calculée (S) soit atteinte.
