The present invention relates to an automatic pipe working apparatus, and comprises; a carriage (10) driven along an outside diameter of a pipe (1); and a chain (2) to adhere the carriage (10) to the pipe (1); and a tension control unit (20) to adjust tension of the chain (2) inside; and a rotary tool (30) attached to the carriage (10) to work the pipe (1). Therefore, by allowing driving in adherence to an outside diameter of the pipe with the use of a chain by the carriage, moving and installation of a working apparatus are easy, and defects on pipe working faces are prevented while facilitating replacement of working tools by enabling automatic cutting off and improvement of working faces by the rotary tool with attachment of a working tool, and there are additional effects such as allowing application to pipes of various sizes with one unit of carriage by adjusting chain lengths. |
