What is Fatigue? If you ask this question, all engineers working in Pressure Equipment design will certainly give the correct answer: Fatigue is that phenomenon, for which in metallic structures subject to cyclic loading, in some particular location, after a certain number of load cycles, a fatigue crack will be…
The use of Finite Element Calculations in Pressure Equipment Design has now become a standard procedure either in USA or in Europe, in all cases where the traditional “Design by Formulae” is not able to provide a specific solution. Such calculations are in fact much cheaper now than they were…
With the latest course, held in October 2024, we have reached the 7th edition of our English language on-line course on the design of pressure vessels and heat exchangers. Many persons from different countries have attended this course edition, which proved to be a very appreciated learning opportunity on the most challenging aspects…
What is the procedure to prepare harmonized standards for pressure equipment? As all the “New Approach” directives, the Pressure Equipment Directive (PED) cannot be applied without standards that are capable to translate into detailed instructions the Essential Safety Requirements contained in the Directive. In fact, the Directive itself doesn’t contain…
This question comes out many times in the work of heat exchanger designers. The answer is needed whichever is the pressure vessel standard to be used. The normal situation in which the engineer charged of the mechanical design of shell and tube heat exchangers finds himself is the following: a…
