ASME B16 47 Series A Flange Dimensions

ANSI B16.5 Class 150 Flange standard covers Steel Pipe Flanges and Flanged Fittings that are
constructed between sizes NPS 1/2 through NPS 24 Metric/Inch. The pressure rating class for the
ANSI B16.5 starts from class 150 to class 2500. The B16 or British standard 16 covers pressure as
well as temperature dimensions, ratings, tolerances, marking, materials, testing, and methods of
designated openings for pipe flanges as well as flanged fittings. Although the term B16.5 or B16 5
are used interchangeability, both these terms refer to same standard. A drawback of using the
ANSI B16.5 specification is that the standard only covers sizes up to 24 inches. For bigger sizes,
suppliers need to follow Copper Nickel ANSI B16.47 Flanges.

Both ANSI B16.47 Flanges Series A and Series B standards define weld neck flanges as well as
blind flanges in raised face type (RF) but only Series A ANSI B16.47 Flanges defines ring type
joint (RTJ) flanges in pressure rating from Class 300 through Class 900 within this standard.
Commercially speaking , the ASME B16.47 Series A flanges tend to be more expensive as
compared to ASME B16 47 Series B flanges. Since the ANSI B16.47 Pipe Flanges in Series B
has a smaller bolt circle diameter than that of Series A flanges, it results in less flange
movement after installation.

We at Skyland Metal have expertise to manufacture Carbon Steel Flange B16.47 Series A,
ASTM A105 Flange B16.47 Series B, Hastelloy C22 B16.47 Flange, & Ductile Iron B16.47 Series
A Flange at lowest cost in India compare to China & Korea, because manpower cost is very
less in India compare to other countries such as USA, UK, Dubai, UAE, Korea, Singapore,
Malaysia, South Africa and many others.

& temperature ratings, materials, dimensions, tolerances, and testing for pipe flanges in the
size range NPS 26 through NPS 60. While the pressure ratings for the Duplex Steel ANSI
B16.47 Flanges starts from Classes 75, 150, 300, 400, 600, and ends up to class 900.

Notes
- ASME B16.47 Series A flanges (> NPS 26) are MMS SP-44 flanges. MSS SP-44 also covers NPS 12 to NPS 24
flanges which are equivalent to ASME B16.5. MSS SP-44 is the only source for the NPS 22 flange dimensions above.
- Class 600 Series A dimensions at NPS 38 and larger also apply to Class 600 Series B flanges.
- Dimension B is to be specified by the purchaser. It corresponds to the pipe inside diameter.
- Flat face flanges may be provided at full thickness, C + raised face, or with raised face removed (the latter is nonstandard).
- WNF = Weld Neck Flange.
- The large end of the hub may be straight or tapered.
- For ring joint facings see page 8-6. For weld end bevel see page 8-5.
- For tolerances see page 8-4.
