摘要
针对假冒P91钢管已使用在电站锅炉上的实际情况,在保证安全运行的前提下,为减少损失,本文介绍了历时8年之久,基于风险思想用"2类3步"方法处理的全过程,即用医学的方式将失效模式分"急性病"和"慢性病"2类,针对假冒P91钢管情况分3步走--包括探讨"监控运行"的可靠性、采取的监护措施、验证性检验及后续处理。以供同行在遇到同类问题时做初步判断和参考。
Based on the case in which the fake P91 steel pipes were used in utility boilers, this paper reviews ＇Two Types, There Steps＇ method used in overall processing procedures for eight years to ensure operation safety as well as reduce the loss. This method divides the failure mode into two types as medicine ways, including acute disease and chronic disease. Besides, there are three following steps that we should consider according to the case. It is necessary to discuss whether it is reliable to monitor the operation, to know what protective actions we should take, to discuss how to do the verification experiments and what we would do after them. The paper is for the peer to make a preliminary judgment and reference in similar cases. There may be some unscientific or even wrong viewpoints and practice in it.
