Thank you guys for your help. LittleInch, no there are still nozzles connected to both vessels, just for simplification I didn't draw them in the pic.

r6155, the both vessels are already installed. The manufacturing procedure is such that we couldn't test them before installation. (See attached pic.) 1. We first manufactured the inner vessel(36inch) with 3 and 2 inch nozzle openings 2. We then inserted it inside the 40inch jacket and closed...

IdanPV, What is Interpretation BC-79-603?

Hello, I have a fully covered jacketed vessel. That means the jacket is fully covering the inner vessel, including heads at both ends. Inner Vessel internal working pressure is 1.2 Mpag @ 40C. Jacket internal working pressure(Inner vessel external pressure) is 0.3 Mpag @ 40C. I want to...

Cobra17, Thank you very much for your replies. I took a look at UG-53. The same ligament eff. is used in App. 13, however in UG-53 it says ligament eff. for holes drilled on cylindrical shell. Is this ligament eff. the same for both cases?(drilled shell and drilled plate) In UG-53 theres this...

Thank you guys. Actually my Air Cooler header boxes are as per Sketch 7 and 8. As it is shown in the code its just a plain sheet whereas my air cooler has holes for fintubes(The tubesheet). Where do I consider that in my calculations?

HI everyone, Does anyone have a excel sheet or equivalent software for designing a rectangular vessel? I am trying to design air cooler headers box. I would appreciate if you could help me with this. Thanks

Thanks 3dDave and TGS4 for your comments. I neither have a mentor nor the budget for participating in a training(for now). But even before taking any course, I would like to learn all these stuff first.

TGS4, Please take a look at the attached file. I found it from a Youtube webinar video. From the chart we can see that Linearization method is done only in case of Elastic stress Analysis. Does this mean that for Elastic Plastic and Limit load analysis we can only use non-linear...

Thank you TGS4 for the comment. Its been a week since I started to analyze the code in detail. I can now understand that after reading and researching more about part5. As for now lets consider there are 4 different failure modes that we must protect the vessel against. Each point has its own...

Thank you IdanPV.

Hello All, I am new to ASME VIII Div 2. I am trying to understand part 5 DBA procedure. This is what I understand from the code: There are two ways to perform the analysis as per part-5: 1. Non-linear method - Elastic-Plastic 2. Linearized method - Elastic Stress We perform these two analysis...
