- 摘要:
- 某油田公司液化气罐区4台400m3液化气球罐,发现有不同程度的裂纹,为此从组装、焊接、材质、机械损伤、应力腐蚀这5个方面分析了球罐安装过程中导致裂纹产生的主要因素;针对4台球罐的具体情况,又从线能量的控制、焊缝表面缺陷的修复、内部缺陷的修复、球罐热处理等方面提出了修复措施。实践证明,修复措施可靠,保证了球罐的安全运行。
Different extents of cracks in 4 sets of 400 m3 liquefied gas spherical tanks at an oilfield company were found. Therefore, the main factors leading to cracks during the spherical tank installation were analyzed. According to concrete conditions of the 4 tanks, repair measures were put forward with respect to linear energy control, repair of surface and interior welding defects as well as heat treatment. It is shown that the repair measures are reliable to ensure the tank safe running.2009,1(1): 60-61 收稿日期：2008-4-11分类号：TE972作者简介：刘振干（1974-）, 男, 河南洛阳人, 工程师,1997 年毕业于郑州工业大学化工工艺专业, 从事石油化工工程的施工和技术管理工作。
