摘　　要：加装螺纹套是修复核电厂设备法兰螺纹孔损伤的一种常用手段,被损螺纹可得到快速有效地修复,且螺纹的承载能力和抗疲劳能力得到提高。在螺纹套修复不符合项的核安全审查过程中,应对标准符合性、螺纹套的材质、实施方案、服役分析、跟踪措施等方面进行全面审查,以保证修复的可靠性和质量。Fitting threaded inserts is a common means of remedying of internal threads deterioration founded in flange of nuclear equipments, by which defective internal threads can be repaired rapidly. Moreover, the bearing capability and anti-fatigue capability can be improved. During nuclear safety reviewing on non-conformance of threads deterioration, more attention need to be paid＇to the conformance with standards, material of inserts, implementing program, service analysis, inspection measures and feedback in order to ensure the reliability and quality of threads remedy.
