Abstract:
A pipe drive system includes a gripping device configured to couple with a pipe element. A housing of the gripping device is configured to extend over and at least partially around a distal end of the pipe element. Torsional clamp devices are configured to engage an outer circumferential surface of the pipe element with frictional engagement features that extend radially inward from the housing. A sealing mechanism is configured to shift a pipe seal relative to the housing and into engagement with the distal end of the pipe element and to facilitate fluid flow through the gripping device into the pipe element.
