CA 2502759
Makeup plates (74, 84) on the abutting surfaces of a tool joint pin (60) and a tool joint box (80) are provided. The makeup plates are recessed in a short distance from the outer diameter of the tool joint elements, such that when the joint is made up, the makeup plate develops an easily visible gap (94) between the tool elements. In this way, a quick determination may be made, without measurement, as to whether the joint can be refaced, or require remachining.
Selon l'invention, des plaques d'assemblage (74, 90) sont disposées sur les surfaces contiguës d'une clavette de raccord de tige (60) et d'une boîte de raccord de tige (80). Ces plaques d'assemblage sont légèrement en retrait par rapport au diamètre extérieur des éléments de raccord de tige, de façon que lorsque le raccord est établi, les plaques d'assemblage forment un interstice (94) facilement visible entre les éléments de raccord de tige. Ainsi, il est possible de déterminer rapidement, sans mesure, si le raccord peut à nouveau être surfacé ou s'il nécessite un nouvel usinage.
