Abstract

Eine Zentriervorrichtung (1) für rohrförmige Elemente weißt einen inneren Teil (2) aus einem Werkstoff mit hoher mechanischer Leistung und chemischer Stabilität und einen äußeren Teil (3) auf, der auf dem inneren Teil (2) angeordnet ist und der aus einem selbstschmierenden Werkstoff mit kleinem Reibungskoeffizienten und mit geringerer mechanischer Leistung und chemischer Stabilität als der Werkstoff des ersten Teils (2) besteht. Die Zentriervorrichtung (1) ist für insbesondere volle und hohle mechanische Pumpstangen, wie sie in der Erdölförderung benützt werden, bestimmt.
