ASTM A182 F51 Duplex Stainless Steel Weld Neck RF Flange
ASTM A182 F51 weld neck RF flange is manufactured from duplex stainless steel forging material and is designed for pressure piping systems, chemical processing equipment, oil and gas facilities, and industrial applications.
The weld neck raised face flange is connected to the pipe through butt welding, providing a smooth transition between the flange and pipe system. This flange design is commonly selected for high-pressure and high-temperature piping applications where dimensional accuracy and mechanical strength are required.
Manufactured according to ASTM A182 / ASME SA182 requirements, F51 flanges are produced through forging processes with controlled material composition, mechanical properties, dimensions, and inspection procedures.
Standard: ASTM A182 / ASME SA182
Material Grade: F51
UNS Number: S31803
Material Type: Duplex Stainless Steel
Flange Type: Weld Neck Raised Face (WN RF)
ASTM A182 specifies forged alloy and stainless steel piping components for pressure systems, including flanges, fittings, valves, and related components.
F51 is a duplex stainless steel grade containing chromium, nickel, molybdenum, and nitrogen alloying elements.
Typical characteristics:
The weld neck flange includes a tapered hub that provides a gradual connection between the flange and pipe.
Common advantages:
The raised face design provides a defined sealing surface for gasket installation.
Common gasket types include:
F51 stainless steel billets are forged to produce flange blanks with required mechanical properties.
Heat treatment is performed according to ASTM A182 requirements.
Typical processes include:
Precision machining includes:
Final inspection includes:
