Seismic Structural Analysis of a Heat Exchanger system

The Client:

A Small and Medium enterprise involved into manufacturing and design of Heat Exchangers


To predict the stresses generated for a Heat Exchanger subjected to an earthquake loading event using FEA Analysis methodology.

Client Expectations:

Seismic Analysis report was expected from client's end. The hidden aspects from client were to select right size mesh for FEA Analysis, select appropriate boundary conditions and conduct an accurate FEA Analysis.

FEA Analysis Project Challenges:

The project had challenges such as referring to the correct standards in order to find out the correct spectrum for the given seismic zone. Our experts had to ensure that the parts are correctly meshed and since it was an assembly level analysis, they also needed to ensure that all the requisite contacts are being modeled between the components.

FEA Analysis Project Deliverables:

Project deliverables included a FEA analysis report for Seismic Analysis with a summarized stress and deformation values along with the calculated Factor of Safety for every components. The summary of the results was backed by stress and deformation plots for individual components in the FEA Analysis report.

FEA Analysis Project Benefits:

The Seismic FEA Analysis results provided by Desserve Engineering not only predicted the stress levels for all the components, we also provided the Factor of Safety for major components and concluded the FEA Analysis report. It saved about 2 months of time for the client since their Testing equipment would be ready by that time. Considering all the resources required for this Testing, the realizable savings could go up to approximately 15000 USD. In addition to the time saved for product testing, FEA Analysis approach for Seismic Analysis also provided an opportunity to learn some critical standards for Seismic Analysis such as EN 1998 and IS 1893. Since it was for Heat Exchanger, our FEA Analysis project team also referred to TEMA standards. Our FEA Consultant provided the learning insights into the FEA analysis report. Our FEA Analyst could learn the right approach for solving the FEA Analysis model for Seismic Analysis problems.

Customer Delight Experience:

The client expected us to complete the FEA Analysis project within 10 working days which we delivered in 4 working days. Our FEA experts examined the project both from the Heat Exchanger domain and FEA Analysis aspects. Our FEA Consultant provided critical remarks of the FEA Analysis report and provided his feedback to include as recommendation for design to the client. The client liked the systematic work approach by our FEA Analysis project team and appreciated us for it.

Market Insights for Pressure Vessels:

The pressure vessel industry is having a steady growth and is yet expected to grow at a steady rate with challenging designs which is evident from the graph below. However, innovation driven product development will challenge the conservative design used by majority of the manufacturers. Today, ASME standards are referred to design pressure vessels for various applications. New challenges and concept drives towards using FEA Analysis services to design pressure vessels. The current project itself is one of its kind towards “non conservative” way of designing the pressure vessels and hence FEA Analysis methodology used to optimize the thickness for pressure vessel is appropriate.
