Internal pressure on a pipe made of plates
Internal pressure on a pipe made of plates
(OP)
Hi!!!!
How can I calculate the minimum thickness with ASME Code of a pipe made of rolled plates? I have a pipe of 20" of diameter and on one side it will have a cap, and the other side it will be open. It will carry gas. I have the temperature: 200 Celsius and gas pressure: 7.5 kg/cm2.
Attached I have a pdf file. I`m considering that with 1/4" inch is enough using A-285 GrC carbon steel. I will feed this pipe from a Inlet in one side (close of cap).
How it is a OPEN VESSEL AND NOT A CLOSED VESSEL, I do know how can I make sure about this thickness with an ASME CODE
Any recommendation for it please?

I know where you are going to, I think my problem can be solved with Boiler and Pressure Vessel Code....do I need more dont I?

It is neither a pressure vessel nor is it a piping system in a ccordance with the rules of AASME B31.1/B31.3 or ASME Section VIII

If you can honestly answer "No - My situation will NEVER be a liquid and my gas can NEVER become trapped in the vent tube and become pressuriaxed" then your problem become a structural one of resisting the static loads of the open-ended steel pipe and the wind loads from the outside of the pipe.
How long (tall!) is your proposed vent pipe?
Have ALL of the structural engineer/support engineer/foundations engineer/fluid flow engineer/process engineer in your project reviewed your proposed vent pipe? (They are on your "team" for a reason = They know their fields better than we do, they know your project better than we do!)
Will you ever face earthquake or wind or hurricane loads?
Will you ever face a "sudden rush" of your gasses that will cause the equal of water hammer or shockwave impacts?
