摘　　要：性能变化、原始焊接缺陷和吊架受力不均引起局部应力集中及长期失效的综合作用 ,会引发一段炉猪尾管的不可预见随机性开裂。利用更换猪尾管局部管段并配合严格的焊接工艺 ,消除了猪尾管的开裂现象 ,且节约了大量资金。Change in property, original welding flaws, and non-uniform distribution of force on the hangers result in local concentration of stress and, combined with long-term failure, will lead to unpredictable random cracking of the pigtails in the primary reformer. By replacing partially pigtail sections and carrying out strict welding procedure, cracking of the pigtails is eliminated, thus saving a lot of fund.
