Spherical Pressure Vessel is preferred for storage of high-pressure fluids. A sphere is a very strong structure. The even distribution of stresses on the sphere's surfaces, both internally and externally, generally means that there are no weak points. In the same design condition with the same design pressure, design temperature and material, the thickness you obtain from the internal pressure formula for spherical pressure vessel will be half that of the cylindrical pressure vessel. The design formula for the cylindrical shell is t = PR/ (SE-0.6P) and for the spherical shell is t = PR/ (2SE-0.2P). When the “t” is represented Thickness, “R” the Inside Radius,” S “the Allowable Stress, “P” the Design Pressure and “E” the Joint Efficiency. When you need to make storage for a great amount of pressurized liquid or gas, meaning you need a big volume, then you need a big pressure vessel, so a spherical shell pressure vessel would be more economical. Most of the LPG and LNG storage tanks are spherical vessels.
In this tutorial we gave you an insight on Design of the Spherical vessel using AutoPIPE vessel. Bentley Auto-vessel design and model pressure vessels based on international design codes and local load methods. It reduces manual drawing time and rework with automated detailed drawings. Create fully dimensioned engineering drawings, managing white space and configuring drawing sheet layout.
