Abstract
A pipeline pigging device including a vehicle movable within a pipeline having shape deformations is provided. The vehicle provides a predetermined axial length and outside diameter to define an exterior surface. A plurality of floating backing bar systems are circumferentially mounted on the external surface along the axial length of the vehicle. The floating backing bar system radially extends by a compression force away from the vehicle to contact and introduce a consistent force on the inside pipeline wall as the device moves through the pipeline.
