Problem: The Clamshell is slipping on the pipe or tube
Probable causes:
The Clamping Pads are not in full contact with the pipe or tube.
The clamping pressure is too light.

Weld seams, swelling, or bumps under the Clamping Pads are preventing
full contact.
Dull Tool Bits are causing extra force in the axial and/or radial direction.
The pipe or tube wall is too thin which allows the tube wall to flex and the
machine to move.

Incorrect tool blocks are installed for the size of the pipe or tube being
worked on.
Incorrect tool bit is installed.
