Types of Flanges we export in United States

How to Select the Right Flange in United States

    Flange Type: Choose from welding neck, slip-on, threaded, and lap joint flanges.

    Flange Specification: (example ASME B16.5, ASME B16.47 type A, EN 1092-1, JIS, UNI, DIN, etc.)

    Nominal pipe size (NPS)(NPS): Select the appropriate size for your pipeline system.

    Flange Rating (or class): Ratings vary by standard, such as ASME (150 to 2500), JIS B2220 / KS1503 (5K to 30K), European/Russian (PN 6 to PN 100), and SANS/SABS (600/3 to 4000/3).

    Pipe Schedule: Required for welding neck and socket weld flanges to ensure compatibility with the pipeline.

    Flange Facing Type (FF; RF, RTJ): Standard options include Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ), with RF being the default for ASME B16.5.

    Flange Surface Finish: Options include smooth, stock, and concentric serrated finishes.

    Material Grade: Choose from forged carbon steel, stainless steel, duplex & nickel-alloy steels, or non-ferrous materials like cupronickel, copper, aluminum, and bronze.

ANSI B16.5 Suppliers United States

ANSI B16.5 Suppliers United States - The ANSI/ASME B16.5 standard serves as a comprehensive guide for the dimensions and tolerances of pipe flanges, covering a size range from ½" to 24" Nominal Pipe Size (NPS).

ASME B16.36 Flanges Supplier United States

ASME B16.36 Flanges Supplier United States -ANSI/ASME B16.36 standard stands as a specialized guide, addressing the dimensions and tolerances for a distinct category of flanges known as orifice flanges. Comparable to the widely used ANSI B16.5 standard, B16.36 distinguishes itself by placing a particular emphasis on orifice pressure differential connections.

ASME B16.47 Series A Suppliers United States

Suppliers United States - The ANSI/ASME B16.47 standard is specifically designed to address the dimensions and tolerances of large-diameter pipe flanges, catering to sizes ranging from 26 to 60 inches Nominal Pipe Size (NPS). This standard is instrumental in ensuring the precise specifications for flanges intended for heavy-duty applications where larger diameters are required.

ASME B16.47 Series B Manufacturers United States

Manufacturers United States - The ASME B16.47 Series B standard emerges as a cornerstone in the realm of large-diameter pipe flanges, offering meticulous guidance on dimensions and tolerances for sizes spanning from 26 to 60 inches in Nominal Pipe Size (NPS). Tailored to meet the demands of robust industrial applications, this standard stands out for its comprehensive coverage of pressure ratings, including Class 75, 150, 300, 400, 600, and 900 lbs.

  • Scope and Application :

    • ANSI/ASME B16.5: This standard covers pipe flanges and flanged fittings for use in industrial process systems. It includes flanges with rating class designations of 150, 300, 400, 600, 900, 1500, and 2500. B16.5 is more commonly used for lower pressure and temperature applications.
    • ANSI/ASME B16.47: This standard covers larger size pipe flanges and flanged fittings (NPS 26 through NPS 60) and includes flanges with rating class designations of 75, 150, 300, 400, 600, 900, and 1500. B16.47 is typically used for higher pressure and temperature applications.
  • Size Range :

    • ANSI/ASME B16.5: Covers flanges in sizes NPS 1/2 through NPS 24.
    • ANSI/ASME B16.47: Covers larger flanges, starting from NPS 26 and going up to NPS 60.
  • Flange Types :

    • ANSI/ASME B16.5: Primarily covers weld neck, slip-on, socket weld, lap joint, and blind flanges.
    • ANSI/ASME B16.47: Focuses on larger diameter flanges, and it includes weld neck and blind flanges. It is divided into two parts: B16.47 Series A (MSS SP-44) and B16.47 Series B (API 605). Series A has larger flange ODs and face-to-face
  • Pressure Ratings :

    • ANSI/ASME B16.5: Standardizes raised face (RF), flat face (FF), and ring-type joint (RTJ) flange facings.
    • ANSI/ASME B16.47: Series A flanges generally have larger facings than Series B, and it also includes raised face (RF), flat face (FF), and ring-type joint (RTJ) flange facings.
Flange faces, such as flat face, raised face, and ring joint face, serve different sealing purposes. The choice depends on the type of gasket used and the level of sealing required.
ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers) are closely related organizations. In the context of flanges, both ANSI and ASME standards are often used interchangeably.
ANSI/ASME B16.5 covers a wide range of flange types, including weld neck, slip-on, socket weld, blind, threaded, and lap joint flanges.
ASME B16.47 Series A includes larger diameter flanges, and Series B covers flanges for high-pressure applications.
Raised face and flat face are common flange face types impacting gasket sealing. The choice depends on the application and required level of sealing.
ASME has two institutes and 32 technical divisions within its organizational structure. Volunteer activity is organized into four sectors: Technical Events and Content.
