摘要：针对缺陷对传热管强度的影响以及传热管判废准则问题展开研究,研制了适用于小管径蒸汽发生器传热管极限载荷及爆破压测试的实验装置,对含体积型缺陷及面型缺陷的Inconel 690蒸汽发生器传热管进行了实验研究,并采用有限元法对极限载荷及爆破压进行了估算。在此基础上,研究了传热管的堵管准则,提出了两级评定方法。该评定方法可根据缺陷的深度、轴向及环向长度来综合评价。
In this paper,the effect of flaw on the strength of steam generator(SG) tubes and the plugging criteria were studied.The test device used for measuring plastic limited load and bursting pressure of small diameter tubes was developed and experiments of Inconel 690 SG tubes with local wall thinning and crack flaws were carried out,meanwhile,finite element method was used to estimate plastic limited load and bursting pressure.Based on these methods,a new plugging criteria for SG tubes with two-level assessment was proposed.In this criteria,the thickness,longitudinal length and circumferential length of flaw were synthetically used to assess the safety of SG tubes.
