Finite Element Analysis of Tubesheet Filter Vessel

Finite Element Analysis (FEA) of a tubesheet filter vessel is carried out to evaluate stress distribution at the tubesheet and assess structural integrity under differential pressure as per ASME standards.

Finite Element Analysis (FEA) of the tubesheet filter vessel is carried out in accordance with ASME Section VIII, Division 1 (Edition 2023) to evaluate stress distribution at the tubesheet and ensure structural integrity under operating conditions. The primary objective of this analysis is to assess the vessel’s performance under maximum allowable differential pressure of 5 bar and to identify critical stress regions.

For the purpose of analysis, a detailed three-dimensional model is developed using SolidWorks 2019, and the finite element simulation is performed using ANSYS Workbench 2019. The analysis methodology follows the guidelines of ASME Section VIII, Division 2, Part 5.2 for protection against plastic collapse. Stress evaluation is carried out using the equivalent (von Mises) stress criterion, and results are compared with allowable stress limits as specified in ASME Section VIII, Division 2, including Figure 5.1.

The study includes detailed geometry modeling, material definition, and generation of a high-quality finite element mesh. Mesh refinement is applied in critical regions such as the tubesheet and junction areas to accurately capture stress concentration effects. The analysis considers relevant loading conditions including internal pressure and differential pressure across the tubesheet along with appropriate boundary conditions.

The results obtained from the analysis indicate the stress distribution across the vessel, particularly at the tubesheet region. The critical stress locations are identified and compared against allowable limits to verify the safety and reliability of the design. Based on the evaluation, the vessel is assessed for structural adequacy under the applied loading conditions.

The figure shows the design details and material properties used for the tubesheet filter vessel analysis, including operating conditions, material specifications, and allowable stress values as per ASME standards.
