Abstract
Pipe machining apparatuses are provided. In one aspect, a pipe machining apparatus includes a tool support adapted to both part or completely cut a pipe into multiple portions, and machine a groove in an exterior surface of the pipe. In another aspect, the apparatus has a low radial clearance such that the tool support does not project a significant distance beyond a pipe. In a further aspect, a method of parting and machining a groove in a pipe with a single pipe machining apparatus is provided.
