Research into saddle supported horizontal pressure vessels
Recently, a comparative study was carried out by Walther Stikvoort into the load capacity of saddle-supported horizontal pressure vessels. He compared the L.P.Zick method with the limit load-based method. One of the tools used in this study is the VES software developed by P3 Engineering.

Dimensioning a custom heat exchanger flange with a few simple rules

Dimensioning a custom heat exchanger flange can be done quite quickly using a number of simple rules. Starting with the internal diameter B the flange dimensions can be determined step by step. The end result is a feasible flange with dimensions that can be used to do a stress analysis with, for example, the P3 Engineering VES-software.
