Abstract
Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.
