Pressure Vessels for Pharma Industry

Pressure Vessels for Pharma Industry

In this task we were asked to deliver the numerical verification of plastic capacity and void stability of several pressure vessels. What was challenging in this case was, that due to technical requirements, connection between the columns and vessels was very specific, and required accurate analysis.

This was a pretty demanding situation, since the connections concentrated stresses in the shell, and we had to also design the vessels following linear FEA standard requirements.

Of course, there were other challenges including some very interesting stability cases, but without a doubt the complex connections of the columns in earthquake conditions were the leading issue.

Project Takeaway:

Legacy codes and standards requirements based on linear FEA can be very conservative. Sometimes it’s necessary to strengthen a vessel that is well designed and would normally work just fine… to meet the demands of some of those criteria. Luckily more and more codes allow for fully nonlinear FEA design, so we do not have to be conservative, and still design a robust and safe structures!

What Enterfea’s customers say

The first project we did with Enterfea was a silos design in 2015. Their non-linear FEA analyzes allowed to significantly reduce the costs of that project. Recently with the enormous support and commitment of Enterfea, we did a pressure vessel with imperfections design. Non-linear FEA analyzes allowed to save a project that seemed to be hopeless. The level of complexity and detail of analyzes provided by Enterfea always exceeds my expectations. Łukasz with his knowledge and commitment is a top-class expert in the field of FEA. Having 15 years of experience in the design industry, I can say that at the current level, Enterfea is no longer competing with the competition, they set new standards in the design projects and can only compete with themselves.

We have used Enterfea for a number of large steel tank designs. With the cost of raw materials increasing rapidly, it is vital for our customers that our designs are efficient whilst still being safe and code compliant. This is why Enterfera is so important. The level of detail involved in their complex non-linear analyses provide unrivaled value for money and the service is exceptional – Lukasz goes above and beyond to ensure any queries are answered even after a contract has been completed. His extensive knowledge of FEA gives us peace of mind that value is maximized and risk is mitigated as much as possible in our designs.

We have been working successfully with Enterfea for many years. Enterfea is always a reliable partner for the static design of our conveyor technology. In our current project, we are jointly developing a completely new, statically optimized conveyor system for integration into our standard.

Enterfea is performing all of the designs of silos for us with nonlinear FEA for over 5 years now, and we are very satisfied with the cooperation. Especially since our Customers appreciate the quality of the designs, which leads to more sales for us and no issues with verification of designs by the authorities.
