PROCEDE DE CONTROLE D'UN ETAT DE VISSAGE D'UN JOINT FILETE TUBULAIRE

摘要

This method applies to a threaded seal (14) comprising a male threaded tubular element (18) and a female threaded tubular element (16). In this method, during the screwing of the mail threaded element (18) into the female threaded element (16), a time variation of a dimensional characteristic of at least one of the elements (16, 18) is measured in a predefined direction. Next, the time variation of the characteristic is analyzed to determine a screwing state of the threaded seal (14).
