Good morning gents and ladies. I've recently been designing (or re-designing) a number of S&T heat exchangers to replace existing units in kind (as best is possible while adhering to the code).
I've noticed that body flanges are calculating MUCH thicker (I estimate from memory 40-60% thicker) than the ones on the units that are being replaced. I was wondering when Appendix 2 became mandatory. Can anyone tell me?
