ABSTRACT:
An apparatus for grinding pipe comprises a tool body and means for rotating and advancing the tool body longitudinally through a pipe to be ground. At least one grinding tool is mounted on the tool body carrying a grinding element and adapted to extend outwardly to contact and grind the internal surface of the pipe when the tool body is inserted therein. Force transmitting means, transmits the pressure of a fluid contained in a tool body cavity to each grinding tool to extend the tools and apply a grinding force to the pipe. After grinding the internal surface of the pipe, the pipe is heated to a burn-out temperature, and then sandblasted on its internal surface to produce a surface for receiving a coating material.
