Series B flange
ASME B16.47(Large Diameter Steel Flanges) is a standard for large diameter steel flanges sized from NPS 26 through NPS 60. Series B flanges need more but smaller fasteners(bolts & nuts) than Series A flanges and have a smaller bolt circle diameter than that of Series A flanges. The smaller the bolt circle diameter is, the less flange movement tends to occur.
