ASME B16.47 is a standard for steel flanges that have a large diameter. The size of the diameter ranges between NPS 26 through NPS 60. The latest version of the ASME B16.47 Flanges Dimensions provides dimensions and ratings in both metric as well as in inch units.
Generally speaking, flanges belonging to standard ASME B16.47 Series A tend to be constructed much thicker, heavier and stronger as compared to ASME B16.47 Series B Flanges in the same size and pressure rating.

ASME B16.47 Flanges Standards
Hence, most manufacturers prefer using the ANSI B16.47 Series A Flange since they have the ability to withstand more external loading as opposed to Series B type. While flanges belonging to Series B require smaller fasteners such as bolts & nuts in a larger number in comparison to Series A flanges. Moreover, Series B ANSI B16 47 Class 150 Flanges have a smaller bolt circle diameter contrasting to that of Series A flanges. If the bolt circle diameter is smaller, the movement of the flange tends to be less. With regards to its commercial point of view, ANSI B16.47 Series A Carbon Steel Flanges tend to be more expensive than Series B flanges. Although flanges belonging to series A are considered to be more costlier, its characteristics make it well suited for piping end users or designers who choose to work with Series A flanges of the ASME B16.47 for the construction of a new pipeline or equipment.
