ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.
It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47.
ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.
The pressure-temperature ratings for ASTM A182 F53 flanges are the same as that for other duplex stainless steels.
There are different types of flanges such as slip on flanges, socket weld flanges, forged flanges, blind flanges, reducing flanges and many by their functions.
The flanges shall not be used at temperatures over 600¡ãF [315¡ãC] since it may be subject to embrittlement after service at moderately elevated temperatures.
The flanges could also be manufactured as screwed, threaded or forged types. The forged flanges are made from a single piece of raw material. These are also called the cast flanges.
The flange a182 f53 can also differ in the face type as flat face, raised face and ring type joint flanges.
The astm a182 f53 vs f55 can come in different diameters ranging from ? inches to 48 inches with different pressure classes ranging from class 150 through class 2500.
ASTM A182 UNS S31803 Double Flanges are very durable and will fit any size due to different shapes and sizes. They are made of the highest quality raw materials and are also packed in wooden cases so no damage will be found. They should generally not be welded without filler metal as this can lead to excess ferrite.
ANSI B16.5 Duplex Stainless Steel Plate Flanges are available in pressure ratings from 150 to 2500, and the standard covers pipe nominal sizes from NPS ? to NPS 24. The duplex stainless steel flange material we manufacture meets international standards. We produce different grades of duplex steels that require different qualities to be used in different applications.
