It is mainly used in the storage and transportation of liquid or gaseous materials in the petroleum refining industry and petrochemical industry. Its operating temperature is between minus 50 degrees Celsius to 50 degrees Celsius, and its operating pressure is generally below 3MPa. When compared to cylindrical containers in the same diameter and pressure, spherical tank’s shell wall thickness is only half of the cylindrical container .It costs smaller amount of steel, covers smaller areas, and its basic engineering is simpler. But the manufacture, welding and assembly of spherical tanks is very strict and it costs a lot of inspection work, higher manufacturing. The spherical tank has been widely used in petroleum industry, chemical industry. It is an important and indispensable equipment in petrochemical installations. As the spherical tank is used for storage of flammable, explosive, toxic substances, it should be designed especially carefully. This article will use the large-scale engineering software ANSYS to numerically analyse the dynamic responses of spherical tank under different loads. It will help to guide the design of spherical tank out of wind, seismic, and snow. With the progress of social development and technology, the design and manufacturing of spherical tanks in petrochemical industry has developed towards the large-scale development. The current
