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.
The pressure capacities of the flanges can also be expressed in pressure numbers. The astm a182 f53 uns s32750 flange types come in pressure numbers ranging from PN6 through PN64.
2507 is used for Chemical process industries, heat exchangers, vessels, and piping, desalination plants, high pressure RO-plant and seawater piping, mechanical and structural components, high strength, corrosion-resistant parts.
This type of steel is excellently resistant to shearing as a result of stress corrosion, high thermal conductivity and a low thermal expansion coefficient.
The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
Super Duplex stainless steel offers the same advantages as its Duplex counterpart. The main difference between the two is that Super Duplex has a higher chromium and molybdenum content, resulting in increased corrosion resistance.
It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.
Super Duplex SAF 2507 is a really strong material with great corrosion resistance.
2507 has good weldability and workability, and it’s widely used in desalination equipment, chemical process pressure vessels, piping and heat exchangers.
Super Duplex 2507 has more than twice the strength of conventional austenitic stainless steels in the annealed condition. Type: Seamless, Welded WT: SCH5-SCH80S
S32750 is used for marine applications, flue gas scrubbing equipment, and pulp & paper mill equipment.
Super Duplex 2507 cannot be strengthened by heat treating. Annealing is performed at 1920¡ãF – 2060¡ãF (1049¡ãC – 1127¡ãC), followed by rapid cooling.
The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.
Super Duplex 2507 is used in environments containing high levels of chlorides or dissolved oxygen, such as seawater cooling, salt evaporation, and desalination, geothermal wells.
The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
Super Duplex tubes for the increasing hostile temperature and operating environments – where maximising operating efficiency demands total product reliability. 2507 Super Duplex Products therefore have very his corrosion cracking resistance and tensile strength.
The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.
2507 Super Duplex Stainless Steel was designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
Super Duplex are trace amounts of carbon, phosphorus, sulfur, silicon, nitrogen, and copper. It has great general consumption resistance, proposed for applications up to 600¡ã F, and low rate of warm development.
2507 has high resistance to stress corrosion cracking (especially chloride stress corrosion cracking), high energy absorption, high strength, and erosion. Essentially, and the Duplex alloys are a compromise.
2507 is used for oil and gas industry equipment, offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, and injection and ballast water systems.
Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking (including sulfide stress corrosion cracking), pitting, crevice corrosion and high strength when compared with other stainless alloys.
