球形储罐赤道板与支柱焊接防变形工艺

Anti-Distortion Fixture for Spherical Tank Equatorial Plate and Support Column

在石油、化工、能源、环保、轻工、制药及食品等行业广泛应用的球形储罐,其支柱和不对称赤道板在焊接过程中会发生较大的焊接变形,是影响球形储罐球片曲率不达标的重要原因。从解决球形储罐球片曲率超标难点入手,设计了一款防变形夹具,阐述了防变形夹具的主要结构和工作原理,以及应用和推广价值。

The spherical tank is extensively used in many industry, such as soil, chemical, energy, environmental protection,light industry, pharmacy and foodstuff. Welding between support column and asymmetric equatorial plate will cause welding distortion. Because of such welding distortion, the curvature of spherical shell is hard to reach the requirements of specification. The anti-distortion fixture will solve the difficulty for spherical shell curvature which is out of limit. The article shows the structure and working principle of anti-distortion fixture, apply and popularize value.
