Shell Thickness Calculation under External Pressure in Pressure Vessels

Shell Thickness Calculation under External Pressure in Pressure Vessels
Overview
A. Reference:
- ASME Section VIII Division 1 Paragraph UG-28, Figure UG-28, Figure UG-28.1
- ASME Section II Part D Subpart 3, Figure G, Applicable chart, Table 1A, Table Y-1
B. Application: Vacuum condition, tube, others
C. Symbol and Definition of external pressure calculation in the shell: Factor A, Factor B
D. Minimum Required Data: Design external pressure, Design external temperature, Outside diameter, Length of the shell, Material type
E. Step by step calculation
1. Assume t, Calculate L/Do, Do/t
2. Define L/Do
3. Define factor A
4. Define applicable figure and E
5. Define factor B
6. Define Pa using factor B
7. Define Pa using factor A
8. Iterate t until Pa greater than P
F. Study cases: 1.5 MPa, 200 deg C, Do 500 mm, L 1000 mm, Material SA 516 Gr.70

The videos you post are helping many people like me to gain deeper insight in this field. Thank you.

[@fnengineering]

Thank you for watching and visiting FN Engineering channel

[@shreyashmehta839]

Very well explained. Thank you very much. Plz upload the next video.

[@fnengineering]

You're welcome. Thanks for visiting and watching FN Engineering channel. I hope, I can updated the next video

[@sojibbd6180]

Best of Luck

ALLAH BLESS YOU AMAZING CHANNEL

[@abhisheklad6892]

Very nice 👍. I would request you to please make video on U-Tube thickness calculation for external pressure. This should have two case i.e. with differential pressure and without differential pressure. Thanks in Advance 👍

[@fnengineering]

Thank you for watching FN Engineering channel. Your suggestion is great. We will consider it. Regards, FN Engineering

Where is the second part?

[@fnengineering]

Until now, there is second part for this material

[@bhaveshparmar9727]

The video was very good & helpful. Please improve the quality of the voice. Thank you.

[@JR-ze5ss]

It's quite helpful. I was wondering if you would explain how to calculate shell thickness with stiffening rings.

[@fnengineering]

Thank you for watching and visiting FN Engineering channel . We will consider your suggestion

[@palomar439]

I have a question. What would be the relationship or equation relating External Pressure measured in MPa and Internal Pressure measured as in mbars. For example 1,5 MPa of External Pressure what would it be in mbars of Internal Pressure ?

[@bekirtuncay]

Hello, how do we calculate the shear stresses and von mises values on the outer surface?

[@imranzada937]

hello there, why don't we consider the allowable stress value for a vessel under external pressure?

[@carlosmolinagodoy1115]

thanks for the video. i have 1 question: in my case i have a vessel that contain air and water internally (is a priming tank), i know that the water temperature is 50 celsius, but i don´t know the air temperatura. in this case what should i use like design temperature?

[@fnengineering]

For design temperature you have to choose the larger value. You can estimate working temperature of air such as 60 deg C. So, you can determine design temperature 80 deg C

[@orlandoemanoel2409]

Please, and if my temperature is low? About 2 °C at deep sea?

[@manivannanharikrishnan5752]

Thank you please make video for jacketed vessel

[@fnengineering]

Thank you for watching and visiting FN Engineering channel . We will consider your suggestion

[@MrAndrew778899]

Bro in the Fig. HA-1,what is E and its unit?

[@fnengineering]

E is modulus of elasticity in MPa or ksi unit

[@pettersoncorreia5535]

will you send the spreadsheet?

[@imranzada937]

it was really helpful and I did my project because of your video. BTW I couldn't find your excel sheet related to this video. where I can find it?

[@carlosmolinagodoy1115]

is the 1.5 MPa (study case) a manometric pressure?

[@fnengineering]

1.5 MPa is gauge pressure

[@syedzainabbas895]

Well explained. When will the next part be uploaded?

[@fnengineering]

Thanks for watching and visiting FN Engineering channel. We hope we can make the next video in this month

[@anengineer8647]

Hi sir why did you remove /private videos from pressure vessel series??

[@fnengineering]

Some video have been published again. Please check again

[@vikasmishra1774]

Please make a video on head thk. Calculation under external pressure

Reinforcement excel file is not opening, can you pls upload in excel format

[@fnengineering]

You can see in the spreadsheet, the link has been written in the description

[@suksesselalu2893]

Mau tanya kak, kenapa di factor A itu jika diasumsikan t=10mm dapetnya 0.001800, sedangkan t=8mm dapet 0.001300?

[@fnengineering]

Itu didapatkan dari chart. Nilainya mungkin berbeda dari beberapa orang yang menggunakan karena pembacaan dari chartnya

[@mdirshadali8817]

Where is the second part of the video?

Until now, this video just has one part

I cannot get either. The link for Spreadsht1 and Spreadsht2 are not tally with the video explanation...

Could I get your email- as I have a unique situation on a vacuum vessel to discuss
