Eddy Current Hot Pipe Flaw Detection Abstract An eddy current system and method is discloed for detecting flaws in hot pipe product. The system in- cludes a detector test head (22) having a heat shield (24) defining a generally cylindrical inner wall through which the pipe passes longitudinally. The test head includes structure (50, 62, 64) for spirally directing water onto the inside surface without contacting the hot pipe as it passes through the heat shield. Debris is thereby removed from the space between the shield and the pipe, and the test head is effectively cooled and shielded from the heat of the pipe. Where the pipe is heated above its Curie temperature, such that the pipe is rendered non-magnetic, no normally required saturation coil is needed to magnetically saturate the pipe for eddy current testing, because the coolant flow- ing over the inner wall cools the test head but does not lower pipe temperature below the Curie point.
