Abstract
A device and method for inspecting a width of thread roots of a tubular component for exploration or working of hydrocarbon wells, the device including two arms each including a first and a second end, the first ends being connected together by a deformable portion allowing an angular displacement between the second ends, the second ends each carrying a contact element and a mechanism determining the angular displacement.
Claims4
A method for inspecting a threading of a tubular component for exploration or working of hydrocarbon wells, comprising:
- positioning an inspection device for inspecting a width of thread roots of the tubular component wells, comprising two arms each including a first and a second end, the first ends being connected together by a deformable portion allowing an angular displacement between the second ends, the second ends each carrying a contact element;
- and means for determining the displacement, such that one of the contact elements of the device is in contact with a load flank of the threading while the other contact element is in contact with a stabbing flank of the threading, the two contact elements being within a same thread root;
- measuring the angular displacement;
- comparing the thread root width determined as a function of the angular displacement previously measured with a reference value.
