Stress Analysis of Opening and Offset Nozzle on a Cylinder

Abstract:

FEA(Finite Element Analysis) has been used in the stress analysis of two geometry sizes of opening and offset nozzle, corresponding standards has been included, and the results show that the strength of the cylinder is fit for safety requirement. The stress analysis also shows that the stress distribution principles are not dependent to the sizes of the opening, but closely to the positions. At the same time the magnitude of stress is relative to the size of the opening and the nozzle. So, stress analysis should be conducted to every offset opening and nozzle to ensure the safety of the cylinder.
