ASME Pressure Vessel Design and Analysis
Performing design and analysis of pressure vessels including Nozzles, (Saddle) Supports and other Appurtenances. Analysis includes Finite Element (Stress, Thermal, Seismic / Vibration and Fatigue) Analysis to Codes including AWS, API and ASME B&PV – Ensuring Vessel Structural Integrity.
What is ASME Code?
ASME Boiler and Pressure Vessel (B&PV) codes regulate the design, construction, maintenance and alteration of pressurized equipment. We perform both closed-form Design-By-Formula Methods (ASME Section VIII Division 1) and Design-By-Analysis (ASME Section VIII Division 2) using Finite Element Analysis (FEA).
Why use FEA?
Pressure vessels have wide applications in power plants, as well as the process & chemical industries. Vessels often have openings of various diameters to accommodate manholes, handholds, and nozzles, that develop high stress concentrations which may lead to vessel failure. These geometric discontinuities alter the stress distribution in the neighborhood of discontinuity so that elementary stress equations no longer apply – thus finite element analysis is required.
Our Experience
- FEA Pressure Vessel Design and Analysis to ASME B&PV Code
- Independent Design Reviews – Pressure Vessels, Nozzles & Supports
- Fatigue Analysis of Vessels used to Produce Hydrogen
- Portfolio of ASME B&PV Section VIII Design & Analysis Solutions
Division 1 (Design by Formula) This approach works best on design of simple vessels, without any extreme geometric discontinuities (such as nozzles). For complex loads such as thermal shock or cyclic loading, FEA is used in accordance with Section VIII, Division 1, Mandatory Appendix 46.
Division 2 (Design by Analysis) is often performed using finite element analysis (FEA) to accurately predict stresses in complex vessels. This method provides room for reducing weight while maintaining structural integrity.
