STANDARD FLANGE DATA
This abbreviated flange data summary is to aid system designers in selecting the optimum pipe and duct flanges. The
working pressure at temperature ratings were obtained from applicable flange specifications. Where elevated temperature
data was not available, the rated working pressure at ambient was down rated in accordance with ASME code versus
temperature correction factors.
