36" Reactor simulator design - pipe or plate for shell 1

[timsch]

I am designing a Reactor simulator for a test facility that is being planned for our manufacturing location. It will be a 36" diameter vertical vessel made of CS with flanged top and a dome cap on the bottom, with a maximum height of 15 ft. Design conditions are 175 psi @ 750F, and it will be designed to ASME SECTION VIII, DIV.1. We are looking at a shell thickness of around 1/2"

Would a shell for a vessel like this typically be made from a 36" section of pipe, or formed and welded plate? What would be the pros & cons of each option? Thanks.

I tend to doubt you'd find seamless pipe in 36" dia, thus what you would find would likely be roll & weld. It would probably be to a spec that may or may not be permitted under Sec VIII, Div 1.

IMO, much more straight forward for you to just design as roll & weld. You select the NDE and design accordingly. R&W cyls are inexpensive and common.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Thanks, Mike.
