本文对我国发生事故的球罐及各系统较典型的200台球罐,通过检测所发现的缺陷及造成球罐内外表面宏观及几何缺陷、焊缝内部缺陷、焊缝表面缺陷的原因作了初步分析,并对如何提高球罐的质量提出了看法。本文对我国发生事故的球罐及各系统较典型的200台球罐,通过检测所发现的缺陷及造成球罐内外表面宏观及几何缺陷、焊缝内部缺陷、焊缝表面缺陷的原因作了初步分析,并对如何提高球罐的质量提出了看法。
In this paper, the spherical tanks and the typical systems of more than 200 spherical tanks in our country were initially analyzed by detecting the defects found and the macroscopic and geometric defects on the inner and outer surfaces of the spherical tank, the internal defects of the welding seam and the surface defects of the welding seam , And put forward some suggestions on how to improve the quality of the tank.
