Product Details

DUPLEX STAINLESS STEEL FLANGES

GlenFlange is a supplier of flanges in different types of material that we divide in: alloy steel, duplex/super duplex steel, nickel alloys/ Titanium and copper nickel alloys. Duplex stainless flanges provides excellent resistant to weathering and a very great mechanical strength. We also provide the flanges in various sizes & dimensions as required by the customers.

Specifications and Steel Grades:

· Alloy Steel: ASTM A182 F1/ F5/ F9/ F11/ F22/ F91/ etc.

· Stainless Steel: ASTM A182 F304/ 304L/ 304H/ 316/ 316L/ 317/ 317L/ 321/ 310/ 347/904L/ etc.

· Super Stainless Steel: ASTM 904L, B625-N08904, 317, 317L, 254SMO

· Duplex & Super Duplex Steel: ASTM / ASME SA 276 UNS NO. S 31803, S 32205, S 32550, S 32750, S 32760, etc.

· 70/30 Copper - Nickel Alloy, 90/10 Copper - Nickel Alloy, 80/20 Copper - Nickel Alloy

· TA1、TA2、TA10、TC4、Gr2、Gr3、Gr5

Characteristics

· High Strength AND

· Duplex UNS S31803/S32205 is a ferritic-austenitic stainless combining high mechanical strength, ductility and hardness with excellent resistance to corrosion and erosion.

Applications

· Oil and gas industry

· Offshore platforms

· Heat exchangers

· Process and service water systems

· Chemical process industries

· High pressure plants and seawater piping

· Utility and industrial scrubber systems

· Because of its resistance to chloride pitting and stress-corrosion cracking, S31803/S32205 is finding wide use in place of austenitic stainless steels for handling solutions containing chlorides such as in marine scrubbers. As a result of its wear, erosion and corrosion resistance, S31803/S32205 is particularly suitable for pumps, agitators and other critical components handling hot corrosive slurries.

· Special mention should be made of its performance in the production of fertilizer grade phosphoric acid by the "wet" process where the alloy finds extensive application.

Benefits

· high mechanical property at room temperature;

· considerable resistance to oxidation at high temperatures;

· considerable resistance to tense corrosion;

· good weldability.

Resistance to corrosion.
Excellent resistance to localised corrosion (intergranular, pitting and intersticial stress corrosion). The normal CPT is 35°C. The stress corrosion cracking (SCC) or stress-corrosion for the chlorination is over 150°C.
Working temperature
Working temperature must be maintained at between -50°C and 300°C as this material is fragile.
