Identification system for drill pipes and the like
First Claim
1. An identification system for a component which comprises a body having an outer surface which in use is subject to wear, the system comprising:
- an identification disk which comprises upper and lower faces and a thickness which is defined between the upper and lower faces;
a unique identifying marking which is provided on at least the upper face, the identifying marking corresponding to the identity of the component;
a cavity which is formed in the body and extends from the outer surface to a depth that is greater than the thickness of the disk;
wherein in use of the identification system the disk is positioned in the cavity such that the upper face is directed toward and disposed below the outer surface; and
a lip which is formed from a portion of the body adjacent the cavity and which, when the disk is positioned in the cavity, overlaps an outer peripheral portion of the disk to thereby secure the disk in the cavity without obscuring the identifying marking.

Abstract
An identification system for marking a component which in use is subject to wear includes an identification disk which comprises generally parallel upper and lower faces and a thickness which is defined between the upper and lower faces, a unique identifying marking which is provided on at least the upper face and which corresponds to the identity of the component, a cavity which is formed in the body of the component and extends from the outer surface of the body to a depth that is greater than the thickness of the disk, and a lip which is formed from a portion of the body adjacent the cavity and which, when the disk is positioned in the cavity, overlaps an outer peripheral portion of the upper face to thereby secure the disk in the cavity without obscuring the identifying marking.

13. A method for providing a component with a unique identifying marking, the component having a body with an outer surface which in use is subject to wear, the method comprising:
-
providing an identification disk which comprises upper and lower faces and a thickness which is defined between the upper and lower faces; disposing the identifying marking on at least the upper face; forming a cavity in the body which extends from the outer surface to a depth which is greater than the thickness of the disk; positioning the disk in the cavity such that the upper face is directed toward and disposed below the outer surface; and forming a lip from a portion of the body adjacent the cavity such that, when the disk is positioned in the cavity, the lip overlaps an outer peripheral portion of the disk to thereby secure the disk in the cavity without obscuring the identifying marking. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
