Document Type and Number:
WIPO Patent Application WO2005040657
Kind Code:
A3
Abstract:
In the method according to the invention, after machining successively respective threaded elements at both ends of the tubular component (10), a second orientation gauge is screwed onto the second threaded element to check whether a mark (4) on the gauge comes into alignment with an orientation mark (11) which has been drawn on the component, after the first element has been machined and a first orientation gauge has been screwed onto the latter in axial alignment with a mark provided on this gauge. If not, the machining of the second element is repeated with parameters varied accordingly. Application to the drilling and operation of hydrocarbon wells.
