ASME B16. 47(Large Diameter Steel Flanges) is a standard for large diameter steel pipe flanges sized from NPS 26 through NPS 60. The latest version provides dimensions and ratings in both metric and inch units. The ASME B16.
ANSI B16.47 Flange is a standard published by the American National Standards Institute (ANSI) that pertains to flanges and flanged fittings. Specifically, ANSI B16.47 covers large diameter steel flanges, typically those with a nominal pipe size of 26 inches and larger. These flanges are commonly used in high-pressure and high-temperature applications, such as in the oil and gas industry, petrochemical plants, and power generation facilities.
The ANSI B16.47 standard is divided into two series: Series A and Series B. Each series has different dimensions and pressure ratings. The two series are further divided into classes, with each class indicating a specific pressure-temperature rating. The standard provides detailed specifications for the dimensions, tolerances, materials, and markings of flanges within its scope.

ANSI B16.47 Flanges Exporter
Manufacturer and Exporter of ANSI B16.47 Flanges in Dimension accordance with ANSI/ASME B16.5, B 16.47 Series A & B, B16.48, BS4504, BS 10, EN-1092-1, DIN, etc. Certified with NACE, PWHT, HIC, SSC, Magnetic Particle Test, Dye Penereteration Test etc.
Size Range: ANSI B16.47 covers flanges with a nominal pipe size ranging from 26 inches to 60 inches.
Pressure Ratings: Flanges are classified into different pressure classes, which represent the maximum allowable working pressure at various temperatures.
Series A and Series B: The standard offers two design series, each with different dimensions and ratings. Series A flanges are generally more compact and lighter than Series B flanges.
Materials: ANSI B16.47 specifies the materials for flanges, which can include carbon steel, stainless steel, and alloy steel, depending on the application requirements.
Facings: The standard defines the facing types for flanges, such as raised face (RF) and ring-type joint (RTJ), among others.
Testing and Inspection: ANSI B16.47 outlines the testing and inspection procedures to ensure the quality and integrity of the flanges.
Marking: Flanges manufactured in accordance with ANSI B16.47 should be marked with essential information, including the material, pressure class, size, and manufacturer's name or trademark.
These flanges are commonly used in piping systems where large diameters and high-pressure ratings are necessary. Engineers, designers, and manufacturers refer to ANSI B16.47 to ensure the compatibility and reliability of flanges in their applications.
