摘要
某电厂再热器出口联箱管接头侧(12Cr1MoV)发生连续开裂,对其进行了力学分析、化学分析、金相检验和小试样插销试验。结果表明,管接头侧管子具有再热裂纹倾向是其连续开裂的主要原因。
By mechanical analysis, chemical analysis, metallographic examination and implant test of small implant sample, the reasons for the crack of joint of boiler reheater connecting tube （12Crl MoV） were analyzed. The results show that the crack reason for boiler reheater connecting tube joint is the reheating crack tendency.
