Abstract:
1. A pipe drive system, comprising: a gripping device configured to engage an outer surface of a drillpipe element to be positioned within a wellbore; a top drive configured to impart rotational force to the gripping device; a housing of the gripping device configured to extend over and at least partially around a distal end of the drillpipe element; a seal area positioned along an inner perimeter of the housing such that, when a seal is inserted in the seal area, the seal is arranged to axially abut and engage with an axial face of the distal end of the drillpipe element and an axial face of the gripping device relative to a longitudinal axis of the gripping device; and engagement features of the gripping device configured to extend inwardly from the inner perimeter to facilitate coupling of the gripping device with an outer circumferential area of the drillpipe element.
