High quality flanges manufactured to ANSI B16.5 standards using ST 37 2 carbon steel. These flanges provide reliable strength, durability, and pressure resistance for industrial piping systems. Suitable for applications in oil & gas, petrochemical, water treatment, and power plants, they ensure secure connections, easy installation, and long service life.
Ansi B16.47 Series B Flanges are heavy-duty pipe flanges designed for high-pressure and high-temperature applications. Manufactured to meet stringent industry standards, they offer excellent strength, corrosion resistance, and reliability. Widely used in oil & gas, petrochemical, and power industries, these flanges ensure secure connections and long-lasting performance in critical piping systems.
How do Series B flanges differ from Series A flanges?
Series B flanges are thinner, lighter, and use more bolts of smaller size, while Series A flanges are thicker and heavier with fewer, larger bolts. Series B is preferred in non critical, general industrial service, whereas Series A is chosen for high pressure, high stress pipelines.
What pressure classes are available in Series B flanges?
They are manufactured in Class 75, 150, 300, 400, 600, and 900, which makes them suitable for low to medium pressure applications. For extremely high pressure systems, Series A flanges are typically recommended.
What surface finishes are available for Series B flanges?
They are supplied with raised face (RF), flat face (FF), or ring type joint (RTJ) sealing surfaces. The finish selection depends on the gasket type and sealing requirements of the piping system.
