摘要
针对火力发电厂锅炉受热面小径管对接接头超声检测的特点,阐述了小径管对接接头超声检测灵敏度补偿的原因及灵敏度补偿量测定方法。为了保证小径管对接接头超声检测的准确性、可靠性,检测前建议对灵敏度补偿量进行实际测定。
Aiming at the characteristics of ultrasonic inspection of small diameter tubes in boiler heating surface in thermal power plant, the reason and measuring method of sensitivity compensation for ultrasonic inspection of small tube were elaborated. In order to ensure accuracy of small diameter ultrasonic inspection , sensitivity compensation should be measured actually before ultrasonic inspection.
