ASME B16.47 Class 600 Series A Flange

Product description

What is ASME B16.47 Class 600 Series A Flange?

ASME B16.47 Class 600 Series A Flanges are commonly manufactured using materials such as carbon steel (ASTM A105), stainless steel (ASTM A182 F304/F316), alloy steel (ASTM A182 F11/F22), and other specialized alloys depending on specific requirements. These flanges are designed for high-pressure applications in industries such as oil and gas, chemical processing, and power generation.

The standard dimensions for Class 600 Series A Flanges typically range from 26 inches to 60 inches nominal pipe size (NPS). The facing of these flanges can be raised face (RF), flat face (FF), or ring type joint (RTJ), and the flanges are usually available in welding neck, slip-on, and blind configurations.

Manufacturing processes for ASME B16.47 Class 600 Series A Flanges involve forging, machining, and heat treatment to meet stringent quality and performance standards. The flanges undergo various tests, including hydrostatic testing, non-destructive testing, and dimensional inspections, ensuring they comply with ASME standards.

Applications of these flanges span across industries requiring high-pressure piping systems. They are commonly used in pipelines, refineries, petrochemical plants, and offshore platforms where reliable sealing and pressure containment are crucial.
