摘　　要：介绍了猪尾管开裂的基本情况,通过对开裂部位的成分分析、金相组织分析、断口及EDX分析等,得出猪尾管开裂的主要原因是晶界的析出相弱化了晶界,在高温蠕变和腐蚀的协同作用下产生裂纹。The basic situation of pig tail pipe cracking was introduced. The main reason of pig tail pipe cracking was analyzed by composition analysis, mi- crostructure analysis, fracture analysis and EDX analysis of the cracked part. The precipitated phase in the grain boundary weakens the grain boundary, Variation and corrosion under the synergies of cracks.
