摘要
叙述了高压加氢裂化反应器接管焊缝裂纹现象,通过对裂纹管道的化学成分、宏观形貌、金相及微观形貌等分析,查找裂纹产生原因,并介绍了裂纹的检测方法、管道焊接方案及焊接后的质量检验方法。
The crack phenomenon of the pipe of high pressure hydrogenation cracking reactor was described. The reason of crack with analyse such as chemical composition, macro - appearance, metallographic examination, micro - appearance was found. The inspection method of the pipe, the weld plan of the pipe , the examination method of quality after welded were introduced.
