The control process of a state of a tubular threaded joint atarraxamento

摘要

Abstract invention patent: "the process of control of a state of atarraxamento a tubular threaded joint. This procedure applies to a joint screw (14) which includes a threaded male tubular element (18) and a threaded female tubular element (16).In this case, in the course of the atarraxamento threaded male element (18) in the threaded female element (16), is a measure of a temporal variation of a dimensional characteristic of at least one of the elements (16, 18) according to a predefined direction. And then, it is analyzed the temporal variation of the characteristic to determine a state of atarraxamento joint screw (14).
