About Weld Neck Flanges Series A or B:
Generally speaking, series A flanges are much thicker, stronger and heavier than series B flanges in the same pressure ratings and size. A series flanges withstand more external loading than series B type. The series B flanges are required for smaller diameters than A type flanges. It has a small diameter than series A type. Both series A and B flanges are defined as weld neck flanges. However, only A type flanges offer ring type flanges from class 300 to class 900 with this standard.
From an economic point of view, series A flanges are more expensive than B type flanges. In most piping applications series A type flanges are recommended. But in the refurbishment or replacement or non critical designing series, B type flanges are used.
These flanges are known for their impact strength that is ideal for adverse and critical applications. Due to its high temperature strength, it offers great service in the heating applications without any deformation and elongation. As these are mostly used in the corrosive environment applications we use resisting materials for manufacturing these flanges.
It offers elevated service in the chromium carbide precipitation zone without getting effected. It also offers good service in the severe reducing zones in fluctuating environments.
