Description
Technical Field
[0001] The utility model relates to the technical field of eddy current flaw detectors, in particular to a penetrating eddy current flaw detector capable of improving detection effects. Background Art
[0002] Eddy current flaw detectors are commonly used in military, aviation, railway, and industrial and mining industries. They can be used in the field or on-site. They are versatile, practical, high-performance, and competitively priced instruments. They are widely used for both online and offline flaw detection of nonferrous and ferrous metal tubes, rods, wires, and profiles. They have high sensitivity for detecting defects such as surface cracks, hidden seams, slag inclusions, and open cracks in metal tubes, rods, wires, and profiles.
[0003] Before pipes leave the factory, pipe manufacturers must conduct flaw detection on the pipes to ensure the quality of the pipes leaving the factory. The internal flaw detection of pipes is generally carried out by eddy current flaw detectors. Since dust accumulates inside the pipes, the dust will block the cracks inside the pipes and affect the accuracy of the detection. Therefore, we propose a through-type eddy current flaw detector to improve the detection effect. Utility Model Content
