Hi vinothsvk,
I think that the clause UG-40 of the code, Limits of Reinforcement, will be applicable to the dimension of the reinforcing pad that will contribute to the reinforcement. A reinforcing pad designed as per this will work satisfactorily as far as the code is concerned.
However, the...
Hi takiyasamsama
I think the reason for this has to do with the diameter used in the area calculations. If I am not wrong, the tensile stress area is equal to the area of the circle whose diameter is the average of the pitch diameter and the base diameter. This calculation might have been used...
Hi BJI and tigny
I referred the pressure vessel design manual by Dennis Moss (3rd ed.) for flange design and found that tigny might be on the right path. To present in brief, the manual says that for low pressure equipment, the large diameter bolts would result in an increased bolt circle...
I am a trainee in the Static Equipment design of the Mechanical department. Currently, I have been provided the task of studying the applicable codes for the design of Heat Exchanger and as of now, I am studying the flange design.
I have referred the appendix 2 of the Code for the flange...
Thank you jtseng123, r6155, and BJI for your insights.
Jtseng123, your answer explains it all and I shall follow that path, using a spreadsheet tool and then cross verify it with a software output.
Hi KarimElsaadany.
I think it should be the higher temperature of the two, as the corresponding allowable stress and other corresponding entites would be lower for the higher temperature and hence the safer design.
I am a trainee in the Static Equipment design of the Mechanical department. Currently, I have been provided the task of studying the applicable codes for the design of Heat Exchanger and designing a BEU type heat exchanger.
My question is that are there any guidelines or restrictions for the...
