ABSTRACT:
A pipe turning apparatus for rotatably mounting and turning a pipe and having a threaded chuck member for rotatably engaging one end of the pipe and a chuck fitting for slidably engaging the other end of the pipe. The threaded chuck member reciprocates and is rotatable by a drive mechanism in opposite directions so as to engage and disengage threads on the one pipe end. The chuck fitting slidably receives the other pipe end which may carry thereon a second coupling which remains threaded on the pipe. The chuck fitting may include resilient fingers surrounded by an adjustable collar so as to vary the force for gripping the other pipe end and for quick insertion and removal of the other pipe end from the fitting. The drive mechanism may be activated by the motor of a conventional hand drill. Turning apparatus may include attachments for wrapping the pipe with a web or coating the pipe with a chemical coating composition.
