Dear all,
I am currently designing a hairpin heat exchanger under ASME VIII-1 Ed. 2023 with the following design conditions:
Corrosion Allowance: 1.6 mm
Shell Side Pressure: 10 barg, Temperature: 280°C
Tube Side Pressure: 93 barg, Temperature: 280°C
Joint Efficiency Required by Client: FULL...
Hello everyone,
I would like to ask you for confirmation on a particular comment reported to us for UCS-66 - impact test requirements, specifically regarding the ASME SA-516 gr.70 fine-grained material produced and normalized.
Considering the ASME II Ed.2023, there is the note:
"The steel...
Hello All,
I'd want to show a doubt that comes for standard forgings and large forgings, in particular regarding carbon steel at hight temperature and low temperature.
Considering the ASME SA-350, that specification covers carbon and low alloy steel forgings, requiring notch and toughness...
Hello all
I'd like to ask you one particular point that the NoBo pointed out in a design of an hairpin heat exchanger, defined by the following data:
Calculation Code: ASME VIII Div.1 Edition 2023
Design Pressure SS/TS [barg]: 6.7 + FV / 6.9
Design Temperature [°C]: 111 / 111
Materials: Carbon...
Hello All,
Considering the forging ASME SA-187 Gr.5 and ASME SA-336 Gr.5, I have noticed that, in ASME II Part D they are caracterized by different values on Maximum Allowable stresses, altrough I haven't found any reference about the reason why difference is shown, especially considering the...
Dear all,
We are designing an Heat Exchanger type AES (split ring) with the following specifications:
Design Temperature SS/TS: 370/354 °C
Design Pressure barg SS/TS: 65.2/82.5 barg
Mimimum Design Metal Temperature Requested by Client: -12 °C
Design Code: ASME VIII Div.1 Edition. 2023
Each...
Hello everyone and thanks for your help,
I'd like to know if, regarding to the material ASME SA387 Gr.9, that is not available anymore in ASME II part.D, there is an equal in EN.13445-3 Ed.2021 that we can use as a material for plates. Or, in case, if there would be another material that we can...
