Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection equipment, in particular to an ultrasonic flaw detection equipment used for non-destructive testing. Background Art

[0002] Ultrasonic flaw detection equipment is a nondestructive testing instrument that uses the properties of ultrasound to detect internal defects and structural anomalies in objects. Ultrasonic waves propagate in a straight line through a homogeneous medium. However, when encountering an interface with a different acoustic impedance (such as the interface between a defect, inclusion, or void in a material and the material itself), some of the ultrasound waves are reflected, refracted, and scattered. Ultrasonic flaw detection equipment transmits ultrasound waves toward the object being tested and receives and analyzes the reflected ultrasonic signals to determine the presence of defects within the object, as well as information such as the location, size, shape, and nature of the defects.

[0003] The current flaw detection instruments used for steel pipes have simple structures, poor detection sensitivity and accuracy, and their scope of use in the flaw detection process is very limited, making it impossible to achieve large-scale and comprehensive flaw detection.

[0004] An existing patent (Announcement No.: CN205449892U) provides a steel pipe ultrasonic flaw detection device. This utility model steel pipe ultrasonic flaw detection device is suitable for ultrasonic detection of stainless steel pipes, boiler pipes, precision bearing pipes and other steel pipes for other purposes. When there are cracks in the pipe wall, comprehensive and reliable flaw detection is performed, thereby improving the accuracy of steel pipe flaw detection.

[0005] Existing patents have provided solutions to the above problems. However, when ultrasonic flaw detection equipment is used for operations such as steel pipe flaw detection, it is usually necessary to select probes with appropriate frequencies for different steel pipe types. At the same time, the probes need to be gradually replaced as needed during the flaw detection process. At this time, the existing probe connection method is cumbersome when performing such frequent replacements, which has a negative impact on the flaw detection operation.

[0006] Therefore, an ultrasonic flaw detection device for non-destructive testing is proposed. Utility Model Content
