Descriptions of ANSI/ASME B16.47 SERIES B Weld Neck Flanges and Blind Flanges:
In November 1980, Subcommittee C of the American Society of Mechanical Engineers (ASME) B16 began the development of the Large Diameter Steel Flange Standard. The purpose was to establish uniform dimensions, tolerances, markings, and materials for flanges with Nominal Pipe Sizes (NPS) ranging from 26 inches to 60 inches. This standard aimed to provide consistency and compatibility in the industry.
Prior to the development of the Large Diameter Steel Flange Standard, in July 1952, the Manufacturers Standardization Society (MSS) released MSS-SP44. MSS-SP44 covered flanges for NPS 12 inches to 60 inches with pressure ratings ranging from 150# to 900#. It included various facing configurations such as raised face (RF), flat face (FF), and ring type joint (RTJ).
The initial draft of the Large Diameter Steel Flange Standard was formulated in December 1982. It underwent several revisions and modifications to ensure accuracy and effectiveness. Finally, in 1990, the standard was approved and published. The final version of the standard duplicated the specifications outlined in MSS-SP44 and replaced the API-605 specification.
The Large Diameter Steel Flange Standard consists of two series: Series A and Series B. Both series focus exclusively on weld neck and blind flange specifications. These flanges are available in different materials, including carbon steel, stainless steel, and other alloy materials. The standard aims to provide a comprehensive set of guidelines for large diameter steel flanges, ensuring consistency, reliability, and safety in various industrial applications.

Features of ASME B16.47 Series B Carbon Steel Weld Neck Flanges and Blind Flanges:
ANSI B16.47 Series B flanges are large diameter steel flanges designed and manufactured according to the specifications outlined in the ANSI B16.47 standard:
Design and Construction: ASME B16.47 Series B flanges, including weld neck flanges and blind flanges, are designed and constructed to meet the requirements of large diameter piping systems. They are manufactured with carbon steel, which provides strength, durability, and resistance to corrosion.
Long Tapered Hub: Weld neck flanges have a long tapered hub that provides reinforcement to the connection between the flange and the pipe. This design ensures better structural integrity and reduces the risk of leakage.
Raised Face (RF) or Flat Face (FF): Weld neck flanges in Series B can have a raised face or flat face configuration, allowing for effective sealing with gaskets.
Solid Plate Design: Blind flanges in Series B feature a solid plate design without any opening or bore. They are used to close off the end of a pipe or vessel, providing a secure barrier.
Raised Face (RF) or Flat Face (FF): Blind flanges can also have a raised face or flat face configuration, depending on the sealing requirements of the application.
Size Range: ASME B16.47 Series B flanges are specifically designed for large diameter piping systems. They are available in sizes ranging from 26 inches to 60 inches, accommodating the requirements of such systems.
Pressure Ratings: These flanges are designed to withstand different pressure ratings, which may vary depending on the specific application and customer requirements. The pressure ratings typically range from 75 to 900 pounds per square inch (psi).
Compatible with Various Flange Facing Configurations: ASME B16.47 Series B flanges are compatible with different flange facing configurations, including raised face (RF), flat face (FF), and ring type joint (RTJ). This provides flexibility in terms of gasket selection and sealing options.
Main Differences Between ASME B16.47 SERIES A and SERIES B:
The main differences between ASME B16.47 Series A and Series B flanges are as follows:
Physical Attributes: Series A flanges are typically thicker in flange thickness and heavier in weight compared to Series B flanges of the same size and pressure rating. Series A flanges also have larger diameter bolt holes, whereas Series B flanges have more bolt holes that are smaller in diameter. This difference in physical attributes affects the overall dimensions and bolting requirements of the flanges.
Compatibility: Series A and Series B flanges are not compatible with each other in terms of bolting. The differences in bolt hole size and arrangement make them incompatible for interchanging or mixing between the two series.
Applications: Series A flanges are commonly used for industrial connectors such as valves, pumps, and pipeline separations. They are suitable for a wide range of industrial applications. On the other hand, Series B flanges are predominantly used in pipeline applications.
Price: Series A flanges tend to be more expensive than Series B flanges. This is primarily due to the increased steel weight in Series A flanges, which contributes to higher manufacturing costs.
