I really appreciate your response and links. I think what I am getting at is the BPVC pretty much wants a F.O.S. of 5 when it comes to fasteners. (if I am wrong please point me in the correct direction) Does that go for preload as well? Or are those two things treated differently? How do...
I'm sure this has been talked about before, but I am not finding exactly what I am looking for.
To be specific, I am looking to use M8 12.9 (S ult 174ksi) fasteners for a flanged joint for a pressure vessel. What is the maximum allowed tensile pre-stress allowed in the fasteners?
Thank You
