摘要
某炼油厂制氢装置自投产运行以来,多次发生转化炉上集合管三通接口焊缝开裂事故。从转化炉上集合管材质、工艺介质、焊接质量等方面进行分析,总结出造成焊缝裂纹的主要原因,并提出相应的预防措施。
For one Refineryt Hydrogen Unit, since it has been put into operation, the tee joint weld of the reformer gathering tube was cracked several times. In order to find the cause, the Reformer manifoldstna- terials, the welding quality, the process medium were analyzed, the main reasons caused the crack were sum- marized and a series of relevant prevention measurements were put forward.
