为分析Ｅ－ ４００ 铝合金板翅换热器Ａ流道的爆破失效原因，对Ａ流道中的残留物质进行了各种化学和Ｘ 射线分析，进行了Ａ流道实物模拟爆破试验。依据分析和试验结果认定，是流道的堵塞和铝合金翅片的腐蚀导致了该设备Ａ 流道的爆破失效。
In order to analyze the cause of blasting failure of E-400 aluminum plate fin heat exchanger A runner, various chemical and X-ray analyzes of the residual material in A runner were carried out, and physical simulation of A runner blasting test was carried out. Based on the analysis and test results, it is concluded that the blockage of the runner and the corrosion of the aluminum alloy fin lead to the burst failure of the runner A of the apparatus.
