ANSI B16.47 Series B Flanges are designed for large diameter piping systems where high flow rates are essential and cost-effective, space-saving solutions are required. These flanges are available in pressure classes from Class 75 to Class 900 and are typically used in applications where moderate pressure conditions prevail. Compared to Series A, Series B flanges feature smaller bolt circles and fewer bolt holes, making them easier to install and more economical, especially in systems that do not demand extremely high strength. They are most commonly available in Weld Neck and Blind Flange types, known for their superior sealing performance and load-bearing capability.
