Many years ago, when the calculation report of a pressure vessels (doesn’t matter according to which pressure vessel standard) was composed by a couple of pages, nobody was really worried about nozzle loads: or better, we all knew that piping connected to the vessel could transmit to the vessel wall…
With the latest course, held in May 2025, we have reached the 8th 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 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…
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…
