ASME B16.47 Series B Class 75 Blind Flanges Dimension

ASME B16.47 Series B Class 75 Blind Flanges is designed for cost-effective and compact applications, featuring smaller bolt circles and lighter weight compared to Series A. Class 75 Blind Flanges under this series are used to seal pipeline ends or isolate pipeline sections, widely applied in low-to-medium pressure large-diameter systems.
