Influence of Nozzle Stiffness on Equipment Nozzle Loads and Local Stresses, a Comparative Study
In Petroleum Refineries, petrochemical plants and fixed / floating offshore installations piping design depends mainly on stress analysis. Stress analysis is one of the important parameters which dictate piping layout and support fixation. As a part of analysis piping engineer mainly checks piping stresses, Nozzle loads and displacements for finalizing the line for construction. In the above parameters Nozzle loads play a vital role in finalizing the concerned line as well as equipment vendor nozzle details. Nozzle stiffness is the important parameter in evaluation of various components of nozzle loads. The objective of this paper is to explain the effect/influence of stiffness generated from three different methods (Anchor, WRC and Finite element method) on nozzle load evaluation and shell/nozzle junction stresses. This paper also explains advantages/disadvantages of these methods which will enable user to go for optimization of piping layout and support design in real life problems.
Keywords- Nozzle stiffness, CAEASR II, Anchor, NOZPRO, WRC, Nozzle flexibilities, Vessel / nozzle intersection, General membrane and local stresses
