123549 - Steps in Application of the Alternative Nozzle Reinforcement Rules for Gasketed Plate Heat Exchangers 

This paper is a continuation of the work of previously developed alternative nozzle reinforcement rules for gasketed plate heat exchanger (GPHE) end plates. A staged approach has been adopted in the framework of development of the alternative rules. In the first stage, an analytical approach has been utilized using the basis of ASME BPVC Section VIII, Div. 1, Section UG-39, and the principles and data of a simply supported plate theory. In the second stage, Finite Element Analysis (FEA) has been conducted with an aim to expand and refine the alternative nozzle reinforcement rules for GPHE end plates. The philosophy that has been followed in development of the alternative rules assessed the impact of nozzle size and location on bending stresses in the GPHE end plates with the goal to optimize the design thickness of the GPHE end plates. Additionally, the limits of the design approach have been defined.

The objective of this paper is to present application of the alternative nozzle reinforcement rules for GPHE in a concise step-by-step manner. Additionally, the paper will present the geometrical limitations for the application of the rules. Overall, the paper would conclude the work of development of the alternative nozzle reinforcement rules for GPHE by incorporating the results of the previous two stages of the work conducted and published.
