Abstract
The apparatus of the present invention is a machine for feeding, indexing, testing, and storing tubular goods. The machine concentrates on the end segments of the tubular goods. The machine uses the eddy current test method to test the outer surface, the inner surface, and internal and external threads. The tests may be conducted simultaneously and at each end of the pipe. The pipe is spun during the examination so that the sensors of the inner and outer surfaces, when driven, trace a helical pattern on the pipe, and the thread sensor is driven along the thread by the rotational force applied to the pipe being tested.
