An American company into the design and manufacturing of pressure vessels for the oil and gas sectors worldwide.
The company was looking to partner with CAE experts for Pressure Vessel FEA Analysis and Life Estimation Consulting as per ASME Section VIII, Div-2, Part 5 (DBA).
Identifying all the factors (as per ASME) and the critical locations in the vessel where peak stresses are expected.
Preparing structured hexahedral mesh of complete pressure vessel without losing critical areas of peak stresses like nozzle fillets, etc.
Fatigue calculations for allowable stresses of different components (Shell, Nozzle, Dish End) and comparing against the predicted cycle life of the vessel.
Completing all analysis and calculations within quick turnarounds.
Hitech’s CAE team provided solutions well ahead of the deadline. This included
FEA Analysis and Life Assessment
Re-evaluating and enhancing operating parameters for engineering analysis.
Modeling and Simulations
Performed analysis of the model for fatigue stress through FEA techniques using ANSYS. After finding maximum stress, stress range, maximum deformation points, etc.
The geometry was meshed with hexahedral elements using ANSYS WORKBENCH, following the quality criteria provided by the client.
Structural assessment using ANSYS and Fatigue life calculations according to ASME Section VIII, Division 2, Part 5.
Accelerating through Automation
Used ANSYS APDL, plugins and developed in-house programs (as per ASME) to speed up work processes.
