Abstract:
One embodiment provides an adjustable guide 10a to steer the end 90 of a pipe string 88 into position to be engaged and supported by a pipe gripping apparatus such as, for example, an externally gripping elevator assembly 10. The adjustable guide 10a may comprise a plurality of angularly distributed guide inserts 30, each having a sloped surface 30A to engage a pipe end 90. Another embodiment provides an adjustable guide 60a to steer a pipe connection into position to pass through a spider 60. The guide inserts 30, 80 of an adjustable guide may be controllably positionable to together form a guide that is concentric with the bore of the tapered bowl of an elevator assembly or a spider. One embodiment comprises a guide insert retainer 11 having a plurality of channels 28, each slidably receiving a guide insert 30 and positionable by rotation of a threaded shaft 40.
