Brief description of the control of a state of the screwing of a tubular seal 1 shows an axial half cross section

摘要

This process applies to a threaded joint (14) comprising a male threaded tubular element (18) and a female threaded tubular element (16). In this process, during the screwing of the male threaded element (18) in the female threaded element (16), one measures a variation with time of a characteristic dimension of at least one of the elements (16, 18) according to a predefined direction. Then, the temporal variation of the characteristic in order to determine the state of the screwing of the threaded joint (14).
