| titleOfInvention | Steel pipe magnetization eddy current thermal imaging defect detection device |
| abstract | The utility model discloses a steel pipe magnetization eddy current thermal imaging defect detection device, which comprises a direct current magnetizer, a high-frequency alternating current heater and an infrared camera array, wherein the high-frequency alternating current heater is in a ring-shaped spiral pipe structure, the direct current magnetizer comprises a plurality of annular coils which are parallel to each other, and the annular coils are all electrically connected with a direct current power supply; the high-frequency alternating current heater is arranged between the two direct current magnetizers, and the two direct current magnetizers are coaxial with the high-frequency alternating current heater; the infrared camera is in communication connection with the processor, and the processor is in communication connection with the PC terminal. The whole device can realize the detection of the internal defects of the steel pipe, and the traditional eddy current thermal imaging device can only detect the defects of the surface or the near surface of the steel pipe. The safety coefficient is high, any coupling agent is not needed, non-contact detection can be realized, and damage to the surface of the steel pipe is reduced. |
