Nominal Pipe Size	Outside Diameter of RF R	Outside Diameter of Flange O	Minimum Thickness of Flange tf	Length through Hub Y2	Diameter of Hub X	Bore B2	Diameter of Pressure Connection TT	Bolt Circle	Number of Holes	Diameter of Holes	Diameter of Bolts	Machine Bolts	Stud Bolts

Notes:

A) Dimensions are in millimeters, except for bolts and bolt holes.
B) Welding neck flanges NPS 3 and smaller are dimensionally identical to Class 600 flanges and may be so marked.
C) All other dimensions are in accordance with ASME B16.5.
D) Other NPT sizes may be furnished if required.
E) For slip-on and threaded flanges, verify that TT drilling extends to inside diameter of pipe after assembly and is free from burrs.
F) Bolt lengths include allowance for orifice and gasket thickness of 6 mm (0.25 in.) for NPS 1 to NPS 12 and 10 mm (0.38 in.) for NPS 14 to NPS 24.
G) In conformance with ASME B16.5, stud bolt lengths do not include point heights.
