自2001年来,TOFD检测技术因其高可靠性、高精度、廉价以及高效的优点,被广泛地应用于国内的锅炉、压力容器和压力管道的检测中。对TOFD检测技术在国内的应用与发展作详细介绍。分析TOFD检测技术原理的同时,指出了其优缺点。同超声检测技术相比较,TOFD检测技术更适用于对压力容器、锅炉的检测。最后列举了国内TOFD检测技术在用标准,并对其发展趋势作了预测。相信,自主研发的设备及相应关键技术将是国内今后发展的重要方向。
Since 2001, TOFD detection technology has been widely used in the detection of domestic boilers, pressure vessels and pressure pipes because of its high reliability, high precision, low cost and high efficiency. TOFD detection technology in China for the application and development in detail. While analyzing the principle of TOFD detection technology, its advantages and disadvantages are pointed out. Compared with ultrasonic testing technology, TOFD testing technology is more suitable for pressure vessels, boilers. In the end, the domestic standards of TOFD testing technology are listed, and the forecast of their development trend is made. Believe that independent research and development of equipment and the corresponding key technologies will be an important direction for the future development of the country.
