Does anyone have a recent copy of CFR-46 that outline the requirements for relief valves on pressure vessels?

CFR 46 comes up as shipping?

Are you sure about the number?

You should be able to download from the govt website?

Also: If you get a response it's polite to respond to it.
 
I believe ASME VIII-1 UG-125 thru UG-136 will also tell me what I need. If anyone knows where I can view a free copy of this, it would be greatly appreciated.
 
But what do you need this for? Your relief valve requirement is well known.

Do you have a specific question?

Have you searched this site especially the safety relief valve forum?

Asking for copyrighted documents is frowned on here.

FYI. ASME VIII-1 Pressure-relief requirements are now in new ASME XIII (2021).


*** Per ISO-4126, the generic term
'Safety Valve' is used regardless of application or design ***

*** 'Pressure-relief Valve' is the equivalent ASME/API term ***
