- 摘要:
- 结合施工现场实际情况,以80万t/a重油催化装置反应沉降器和再生器的现场安装为例,介绍了大型压力容器现场拼组装工艺、组对及焊接胎具结构、自动埋弧焊接技术.工程应用表明:采用这种现场组对自动焊接技术,焊接质量易于保证,与手工电弧焊相比,焊接工效提高了4~6倍.
Regarding to construction conditions and taking site installation of reaction subsider and regenerator of 800, 000 t/a heavy oil catalysis unit as example, this paper introduces site assembly technology, assembly, welding model and auto - submerged are technology for large pressure vessel. Welding quality is easy to be assurance since the site assembly and auto - welding technology are adopted. Comparing to manual welding, it rises 4 ~6 times of welding effect.1999,2(2): 41-44 收稿日期：1998-11-12
