ASME B16.47 Series A & Series B
ASME B16.47 includes Series A and Series B dimensional configurations for large diameter steel flanges.
The two series have different dimensional requirements, including flange outside diameter, thickness, bolt-hole arrangement and other geometry. Therefore, Series A and Series B should not be treated as automatically interchangeable.
Customers should clearly specify the required Series A or Series B when placing an order.
