JStephen thanks for the info. The design pressure of the tank is 5 psig so I can't use API 650 exclusively. Is it possible to design under two different API Codes?
I am confused about the 2004 ASME B&PV code standards. Why is the 1996 version of B16.5 used and not the 2003 revision? If anyone could shed some light on this subject I would appreciate it.
Thanks,
Patrick
