The stiffness curves given in this paper can also be utilized to determine the elastic deformations of the tank shell for the calculated end forces at the nozzle connection due to the attached piping. 展开 关键词: Stress Nozzles Stiffness Storage tanks Force Pipes Shells Junctions Piping systems ...
If those loads were derived assuming a "fixed" nozzle, they may be overly high. If it's just a standard load to be applied to all nozzles/tanks, it may be unreasonable for your particular tank. It's not uncommon to have nozzle loads specified just as an exercise with no real meaning...
