With a background of Chemical Engineering, I have found it's hard when I first join in as a design engineer for pressure vessel. Most of the time, I have to spend long hours reading the ASME VIII Div 1 code book to understand the design principle for UPV. For me, the code book is like a "foreign language". It is really a painful experience when you have to review the design without a good overviewon the code. Thanks Lutz's well-structured lesson, I could understand and appreciate the code now. Lutz had simplified the code book nicely and most importantly had guided on the correct way to interpret the code. I would strongly recommend graduate engineer like me to join the class. No regret for sure!
