Effect of heated region on stress relief ratio of local heat treatment on spherical tanks;

An Experimental Investigation on the Welding Technology of WEL-TEN 610CF Steel for 10 000m3 Spherical Tanks of Natural Gas;

Analysis of the Influence of the Diameters of the Tie-Rods on Spherical Tanks Under Earthquake Loads;

Residual stress analysis of a 1500m~3 liquefied petroleum gas spherical vessel;

This paper introduced the harm of the rupture of the liquefied petroleum gas (LPG) spherical vessel that is caused by corrosion, and analyzed corrosive reason of spherical vessel in Beijing Yanhua Petrochemical Co.

This paper analyzes the shape of the crackles forming on the 200 m3 spherical vessel for liquid ammonia from the aspects of the stress state, metal material and corrosion media as well as the cause for the crackles forming through inspection.

The finite elements stress analysis and calculations were done for 1 500 m3 curvature super standard sphere tank under design and hydrostatic testing pressure,and strength check had been executed according to the stress analysis and design method.

On the basis of FEM stress analysis of a sphere tank, it can be concluded the arrangement of weld in high stress area which was one of the most important exterior factors that cause weld cracks.

Regular inspection of sphere tank is very important to ensure tank quality and human security,which includes safety risk identification,safety risk control,and quality control of auxiliary operation.
