The thing that isn't adding up is that I'm a Chemist and so this is new to me.
I realise the standard for 8" is 2.77mm, (The 2mm has been arranged for us and is pressure rated above the needed 150 KSI, it's also cheaper and lighter then the 2.77mm) which was why I was asking for the equation...
Sorry, I should have said, after looking through ASME B16.9 and calling a supplier they suggested that 6mm is the thickness needed.
They're suggestion was a 6mm thick flat 304l end plate, to hold the 150PSI. As they don't stock pressure rated end caps. (I presume there end caps are a miss match...
racookpe1978 - Unfortunately we couldn't get in contact with the death star manufacturers to get hold of the impervium-coated 304l :).
After looking through ASME B16.9, I'm right in thinking I need a 6mm plate?
It's to be welded to a 2mm thickness 304l, 8inch OD pipe, needing to hold 10bar/140PSI.
Again thank you for your reply Metengr. I'll be sure to look up that section tomorrow in work.
If it makes a difference to your suggestions the item is at a pressure of 150PSI, at a temp of 300K, (25degsC)?
Thank you for your reply metengr. Yes I understand what you are saying, but I'm currently just after a quick fix. Is there even an equation to find out the thickness I require?
The part is needed for a prototype. Once this proof of concept has been made, the professionals will be brought in.
Thank you for your reply. The overall component needs to be pressure rated to at least 10 bar and so I need a calculation to show that the thickness of the plate has been taken in to consideration.
I'm currently searching though the companion guide to ASME, boiler and pressure code, but I...
I'm struggling to find the plate thickness that I need to hold 10 bar in a 304l 2mm thick pipe. The plate will be welded on.
Can anyone pass on an equation to find the plate thickness?
Thanks,
