Gentlemen, thanks for such a wealth of information, however not being very good at finding needles in haystacks, I am still struggling to latch on to Transaction of the ASME, not to mention any papers on Mark'l. If anyone can lead me to this site I would be grateful.
Can one look at these ASME publications first before deciding whether to buy or not?
Incidentally Edward Kline sounds awefully familiar, are you related to Jim Kline (piping lead) of FW from Houston many moons ago?
