ABSTRACT:
A machine and method are provided for reconditioning pipelines. The machine comprises parts and modules which are easily stowed, manually portable into and out of excavations, and easily installed together to form a machine for reconditioning the outer surface of pipelines. A frame construction capable of assembly around a pipeline is provided. A travel module is attachable to the frame to move the frame along the pipeline. A traction module is attachable to the frame to provide substantially constant traction during travel regardless of surface irregularities. A ring construciton is provided for placement around the pipeline and rotation about rollers attachable to the frame that engage the inside of the ring construction. Retaining arms and reconditioning devices can be mounted on the ring construction and a rotating module is attachable to the frame to engage and rotate or oscillate the ring construction around the pipeline.
