1. The analysis of the failure According to the above analysis results, it can be known that the main reasons for the failure of the slip-on flange are as follows: (1) GB T 700-2006 standard stipulates that w(C) should be less than and equal to 0. 22% in Q235, and w (C) in this material is 0. 96%. In...
