管材超声探伤是核品检验的重要环节,设备专用性较强,主要针对壁厚较薄的管材。检验过程中水的耦合让一束超声波能穿透过水层射入金属材料内部,探察细微缺陷。由于探测缺陷相尺寸较小,管材壁厚较薄,对设备的机械运行精度要求十分严苛。检验人员和设备检修维修人员常常投入大量时间来维护和调整设备以维持设备的精度。近10年来国内核电的快速发展。生产检验任务逐年递增,超声探伤设备出现了整体老化趋势,设备维护时间也不断延长,影响到了生产进度,因此提高超声探伤系统的稳定性,成为当务之急。
Tube ultrasonic testing is an important part of the verification of nuclear products, equipment, more specific, mainly for the thin wall thickness of the pipe. Water coupling during the inspection allows a beam of ultrasonic energy to penetrate the water layer and penetrate into the interior of the metallic material to detect minor defects. Due to the smaller size of the detection defect phase and the thin wall of the pipe, the mechanical operation precision of the equipment is very harsh. Inspection personnel and equipment maintenance and repair personnel often devote a lot of time to maintain and adjust the equipment to maintain the accuracy of the equipment. The rapid development of domestic nuclear power in recent 10 years. Production inspection tasks increase year by year, ultrasonic flaw detection equipment appeared the overall trend of aging, equipment maintenance also continued to extend, affecting the progress of production, so to improve the stability of ultrasonic testing system has become a top priority.
