The invention discloses an inner-penetrating eddy current detection device for detecting pipes, which comprises an eddy current flaw detector, a probe, a support frame and an air source; In the detection pipe, the probe includes a probe body that matches the shape of the inner wall of the pipe to be tested. A detection coil is wound on the probe body and along the length of the probe body. The eddy current flaw detector is connected to the detection coil through wires; the support frame is installed on the The pipe is close to one end of the eddy current flaw detector, and one end of the support frame extends into the pipe to be tested. The outer surface of the upper part of the support frame is provided with a bar-shaped groove for the wire to pass through, and the middle part of the support frame is provided with a vent hole. The air hole communicates with the cavity between the support frame and the probe. The inner-penetrating eddy current testing equipment can satisfy the eddy current testing of long pipes, has a simple structure, and greatly improves the testing efficiency.
Description
technical field [0001] The invention relates to an eddy current testing device, in particular to an inner-penetrating eddy current testing device for testing pipe materials. Background technique [0002] Domestic research on eddy current testing technology began in the 1960s, and now it is not only applied to regular-shaped tubes, plates, rods, wires and other raw materials, but also used in the detection of parts with more complex shapes. So far, the commonly used eddy current detection methods are divided into placement type, external pass-through type and internal pass-through type. The common inner pass-through types are generally hand push type or mechanical push type. [0003] With the rapid development of metallurgy, chemical industry, aviation, aerospace, nuclear industry and other industrial sectors, eddy current testing technology has been widely used due to its strong usability, non-contact coupling, and light detection devices. Seamless pipes are mainly used in...
