How to calculate the clamp connection?
(OP)
I am working on a 60 years old heat exchanger.
The client want rerate it to higher operating pressure.
However, it use clamp structure instead of girth flange see attached drawing for details.
I can not find any calculation method for this structure.
The only clamp calculation method is ASME Sec VIII div 2 4.17. however the structure is not exactly the same.
Is here anybody have experience to deal with it?
Thanks in advance.

There comes a point in the plodding progress of industry when you simply "gotta buy a new one".
Someone has to take a stand, no matter how many 25 year old MBAs are screaming "makeitwork, makeitwork, makeitwork"
Reworking and uprating 60 year old equipment is a gamble.
Will your MBA boss taking financial responsibility in case there is a catastrophic failure of this ancient heat exchanger under the uprated conditions ?
Or will you be blamed ?
