ANSI B Flange Class – Weld Neck, Series B – Robert-James Sales, Inc.
At least I was not aware. Insist on drawings from 477 that are specific about the type sries flanged connections over 24″NPS. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. One could argue that it is simply adme more efficient design.
From a commercial point of view, the serie B type may be selected for piping with a non critical application. In most end-users piping specifications the Serie A is specified, which can whithstand more external loadings than the Serie B type.
The Series B uses more, but smaller bolts, so the bolt circle diameter is asme b16 47 series b, so the flange moment essentially proportional to the distance between the bolt circle and gasket circle is less for a given total bolt load. FKE makes a good point regarding series A being a heavier design.
Red Flag This Post Please let us know asme b16 47 series b why this post is inappropriate. Note that stress engineers may be of help regarding maximum allowable external loadings.

Generally speaking, newer equipment almost asme b16 47 series b uses series A, but if you are connecting to a nozzle on older or existing equipment, get someone to verify the flange type physically.
Resources Digital bb16 may be the asme b16 47 series b frequently misunderstood and misused term in business discourse today. The problem with large flange series A and B are that there are a mixture of them out there in the field.
I don’t think the Series B are being properly characterized in the response, above.
