ABSTRACT:
Apparatus and methods for inspecting materials such as cylindrical and tubular members are disclosed. One apparatus includes a frame that supports a magnetic coil and a detector assembly, the detector assembly having one or more magnetic detectors adapted to be spaced a first distance from the material being inspected by one or more substantially frictionless members. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.
