摘要
针对乙烯裂解气压缩机五段后冷凝器管箱法兰密封面泄漏,分析其失效原因,对比以往封堵方法的优缺点,提出相应的改进措施,形成新的封堵方法,为大直径、宽间隙的法兰密封面泄漏封堵提供了借鉴。
Leakage was found in the channel flange sealing surface in ethylene cracking compressor five-stage aftercooler. The reason of failure was studied. A new plugging method was presented after comparing the advantages and disadvantages of the existed plugging methods. It will provide a reference for flange sealing with large diameter and thin gap.
