本文提出螺栓法兰连接的紧密性概念,针对螺栓法兰连接长时间在高温条件下会失效的问题,对法兰连接的三个主要部件作了失效分析,从理论上提出了相应的措施以降低因连接失效造成的损失。
In this paper, the concept of the tightness of the bolt flange connection is put forward. According to the failure of the bolt flange connection failure under the condition of high temperature for a long time, the failure analysis of the three main components of the flange connection is made. Corresponding measures are put forward theoretically Reduce the damage caused by the connection failure.
