Structural Analysis of Waterbox - FEA Analysis Model

ASME Design and Analysis

ASME Design and Analysis of equipment to Boiler & Pressure Vessel (B&PV) Code as well as Power (B31.1) & Process Piping (B31.3) Code. This includes (stress, buckling, thermal, vibration, fatigue and fracture) finite element analysis.

We perform both ASME BP&V Section VIII Division 1 (Closed-Form Design-By-Rule Methods) and ASME BP&V Section VIII Division 2 (Design-By-Analysis). Our experience includes:

  • Design & Analysis of Pressure Vessels, Heat Exchangers +
  • Structural, Seismic, Vibration & Fatigue Analysis of Equipment
  • Troubleshooting & Redesign of Process Equipment

Examples:

  • Pressure Vessels
  • Heat Exchangers
  • Piping/ Valves
  • Skids
  • Chemical Reactors
  • Vessel Nozzles/ Supports
  • Filter Housings
  • Nitrogen Vessels
  • Bioreactors
  • Demonstration Vessels

Importance of Fatigue Analysis

Fatigue (from cyclic loading) is one of the most frequent causes of failure in pressure vessels, piping and process equipment. A vibrating component or system often leads to fatigue – which eventually leads to equipment malfunction, or catastrophic failure. Fatigue cracks usually initiate at the surface, and for this reason, the condition of the surface and the environment are important factors influencing fatigue behavior.

Expertise

Tom O’Donnell performs vibration, thermal / fatigue and failure analysis to ASME Codes. Bill O’Donnell Sr. continues to serve as a Contributing Member of the ASME Boiler and Pressure Vessel Code – and has published numerous papers on fatigue and failure analysis.

ASME Fatigue Design / Analysis

Fatigue design / analysis is performed per ASME Section III Class 1 and Section VIII Division 2. The fatigue design life evaluation procedures in Section III of the ASME Boiler and Pressure Vessel Code were originally developed in the U.S. Naval Nuclear Program. Those involved were Bill O’Donnell, (Bernie) Langer, W.E. (Bill) Cooper and James (Jim) Farr – who, in the late 1950’s and early 1960’s developed the initial formulation of this technology. This Tentative Structural Design Basis for Reactor Pressure Vessels and Directly Associated Components, became known as “SDB-63.”

Section III of the ASME Code “Vessels in Nuclear Service” was the first to include specific Code rules to prevent low cycle fatigue failure. Bill, Sr. is currently active on the ASME Subcommittee on Design, and serves as a Contributing Member of the ASME (BPV III) Working Group on Fatigue Strength.
