Embodiment Construction

[0036] exist Figure 1 to Figure 4 The above shows the control equipment of the tubular member. This device is indicated by reference number 10 .

[0037] In the example described, the device 10 is used to control a tubular member 12 comprising an end portion 14 having an outer profile 14A and an inner profile 14B. The end portion 14 of the member 12 is generally threaded to allow a screwed coupling with another tubular member (not shown). In the example shown by the figures, the tubular member 12 includes a male end 16 . The tubular member typically has a length of several meters. The tubular member 12 comprises a body that revolves around a major axis Z ( image 3 ). The inner profile 14B (or outer profile 14A) of the component 12 is defined as the profile of the component 12 , ie the inner profile (or outer profile) of the component around the axis Z of the component 12 . Ideally, the inner profile 14B or outer profile 14A of the component 12 in a plane normal to the ...

Abstract

This device (20) comprises a first sensor (22) of a radial measurement of the tubular component (12) and a support (24) able to drive the first sensor (22) along a circular trajectory in a predefined plane orthogonal to the principal axis of the component (12). In particular, the support (24) comprises a main body (26) able to be fixed by freeable fixing means (28) to the component and a rotation shaft (30) onto which is fixed an arm (32) bearing the first sensor (22) so as to allow the displacement of the first sensor (22) along a circular trajectory inside or around the component (12). Furthermore, the device (20) comprises a second sensor (34) for measuring an angular position of the first sensor (22) for each of its radial measurements, the radial and angular measurements obtained making it possible to determine the profile of the component (12) in the predefined plane (P).

Description

technical field [0001] The invention relates to a measuring device for measuring the inner or outer profile of a tubular component. The invention is more particularly, though not exclusively, applicable to measuring the inner or outer profile of tubular components for oil or gas extraction. Background technique [0002] Such tubular members typically include a male or female threaded end capable of being screwed to the respectively female or male end of another tubular member. The presence of thickness or roundness defects of these tubular bodies is thus particularly critical, in particular for ensuring a satisfactory coupling between the components. Thus, the presence of such defects can produce fatigue and thus cracks in the tubular members at the joints of the defective tubular members. Furthermore, these dimensional imperfections risk causing tightness problems, since the radial interference at the sealing surfaces and threads does not have optimal values ​​for ensurin...
