SS 347 flanges are flange connections made from grade 347 stainless steel, which is a stabilized austenitic stainless steel with the addition of columbium (niobium) and tantalum. These flanges have excellent high temperature strength and resistance to intergranular corrosion.
ASTM A182 F347 is a specification Components developed by ASTM International (formerly known as the American Society for Testing and Materials) that covers forged or rolled alloy and stainless steel pipe flanges,Carbon Steel ,forged fittings, and valves and parts for high-temperature service. Specifically, ASTM A182 F347 is a grade within this specification, denoting a particular type of Stainless Steel alloy.
ASTM A182 F347 is a stabilized, austenitic stainless steel and Steel 347that contains chromium and nickel as its main alloying elements. It also includes columbium and tantalum, which contribute to its enhanced resistance to intergranular corrosion.
These flanges are designed for high-temperature applications. The addition of columbium and tantalum provides improved intergranular corrosion resistance, making ASTM A182 F347 Flanges suitable for service in environments where sensitization and carbide precipitation could be issues.
ASTM A182 F347 flanges find applications in industries such as chemical processing, petrochemical, pharmaceutical, and food processing, where corrosion resistance and high-temperature performance are critical.
The ASTM A182 F347 specification covers various types of flanges, including weld neck, Slip-on, blind, Socket Weld, lap joint, and threaded flanges. Each type is designed for specific applications and installation requirements.
ASTM A182 F347 flanges are manufactured in accordance with the standards set by ASTM International. The forging or rolling process ensures that the flanges meet the specified mechanical properties, dimensions, and other performance criteria.
Flanges produced under ASTM A182 F347 undergo rigorous testing and inspection procedures to ensure quality and reliability. Common tests include mechanical property testing, chemical analysis, non-destructive testing, and dimensional inspections.
Each ASTM A182 F347 flange is typically marked with relevant information, such as material grade, size, Pressure Vessel class, and manufacturer's identification. Certificates of compliance may also be provided to attest that the flanges meet the required specifications.
The ASTM A182 standard for the most up-to-date information on material properties, testing requirements, and manufacturing guidelines. Additionally, users should follow proper installation practices and consider the specific conditions of their applications when selecting ASTM A182 F347 flanges.
