尾气管失稳原因分析及改进措施

Buckling Causes Analysis and Improving Methods for Off-gas Pipe

通过对尾气管的结构和受压进行分析,指出结构不合理是尾气管内管失稳的主要原因。提出了加设防冲板、缩短单根管道长度及增加加强圈的改进措施。

Through the analysis of the structure of the off-gas pipe and the loads acting on it,it is indicated that the improper structure is the main source to cause the buckling of the inner pipe in off-gas pipe.The improving measures,including the installation of anti-impacting plate and stiffener as well as cutting single pipe length, were proposed.
