1 – The safety factor on the tensile strength: historical background In the 19th century, when the first steam boilers started to be designed and fabricated, the most important problem that the designers had to solve was the determination of the allowable stress of the carbon steel plates used in their…
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…
From 18 to 21 May 2026, join us for the 10th edition of our online course dedicated to the engineering design of pressure vessels and heat exchangers — delivered entirely in English. This intensive programme features daily online sessions, with 3-hour morning classes and 3-hour afternoon classes, offering a comprehensive…
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…
