ABSTRACT:
A pipeline and tubular structure renovation apparatus facilitates rapid and economical removal of protrusions into the interior of pipelines and other tubular structures, particularly gas pipelines having excess weld or devices such as nipples, etc. The apparatus consists of a generally cylindrical carriage mounted on wheels or skids which substantially center the apparatus within a pipeline; a clamping device to clamp the carriage in position; and a centrifugal tool head which may perform grinding, cleaning, polishing and other operations. Grinding may be accomplished in both radial and plunge cutting modes. The apparatus is robust and of simple and economical construction Weld removal speed is considerably faster than that achieved by conventional precision grinding tools.
