发明名称 IDENTIFICATION SYSTEM FOR DRILL PIPES AND THE LIKE
摘要 <p>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.</p>
