- 摘要:
- 文章针对近年来炼油化工工程铬钼耐热钢管道焊接中频繁出现因延迟裂纹造成管道焊缝开裂的事故,重点分析了施工过程中有可能导致焊缝延迟裂纹产生的多方面因素,并相应提出了加强铬钼耐热钢管道焊接质量控制的措施及建议。
Accidents caused by delayed cracks have happened frequently during the welding of chrome molybdenum steel pipelines in the refining and petrochemical projects in recent years. This paper analyzes emphatically the reasons for the delayed cracks at weld joints during construction, and puts forward the measures and proposals for enhancing quality control of chrome-molybdenum steel pipeline welding.2013,2(2): 67-69 收稿日期:2012-8-3DOI:10.3969/j.issn.1001-2206.2013.02.020分类号:TG457.6作者简介:锁海滨(1965-),男,高级工程师,1988 年毕业于清华大学化工系,1994 年毕业于石油大学(北京),工学硕士,现从事项目管理工作。参考文献:
