ABSTRACT:
A method and apparatus for swaging pipe, straightening hooked end pipe, and expanding undersized pipe for threading is disclosed in which the pipe is gripped adjacent the end to be swaged by a chuck that also rotates the pipe and a swaging tool engages the end of the pipe and forces the pipe to rotate around the common axis of the chuck and the swaging tool. The distance between the chuck and the swaging tool is such that the bending stress produced in the pipe exceeds the yield point of the pipe to thereby straighten the pipe sufficiently for threads to be cut on the pipe.
