Inflatable eddy current inspection probe for inspection of tubular means

摘要

The inspection probe for inspecting tubular members comprises a plurality of axially oriented plastic strips which form the circumference of the probe with each plastic strip having mounted thereon an eddy current coil. A rubber tube is disposed on the interior of the plastic strips so that when the rubber tube is inflated, the plastic strips and coils are forced outward into close contact with the tubular member so that the eddy current coils can detect flaws in the tubular member. The eddy current coils are held against the tube wall even when the tube has been deformed into an irregular configuration.
