  • Patent number: 7874054
    Abstract: A method for producing a tubular component, in which, after machining successively respective threaded elements at both ends of the tubular component, a second orientation gauge is screwed onto the second threaded element to check whether a mark on the gauge comes into alignment with an orientation mark that has been drawn on the component, after the first element has been machined and a first orientation gauge has been screwed onto the first element in axial alignment with a mark provided on this gauge. If not, the machining of the second element is repeated with parameters varied accordingly. Such a method may find particular application to the drilling and operation of hydrocarbon wells.
