Abstract
Present embodiments are directed to a gripping device configured to cooperate with a pipe drive system or top drive to provide a sealed engagement with drillpipe elements. The gripping device includes a housing configured to extend over and at least partially around a distal end of the drillpipe element. Further, the gripping device includes 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 engage with a face of the distal end of the drillpipe element and a face of the gripping device. Further, the gripping device includes engagement features configured to extend inwardly from the inner perimeter to facilitate coupling of the gripping device with an outer circumferential area of the drillpipe element.
