Inconel 600 Flange and Fittings

Inconel 600 Flange and Fittings

Inconel 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000◦ F(1093◦C). The high nickel content of the alloy enables it to retain considerable resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds.

In Inconel 600 flanges and Fittings or UNS N06600 alloy, nickel content gives it excellent resistance to chloride-ion stress corrosion cracking and also provides excellent resistance to alkaline solutions, while the chromium content of the material provides resistance to weaker oxidizing environments.

The chromium content of Alloy 600 is an improvement over Alloy 200 (commercially pure nickel). In strong oxidizing solutions, like hot, concentrated nitric acid, Alloy 600 has poor resistance to corrosion. Inconel 600 Fittings and Flanges are relatively unattacked by the majority of neutral and alkaline salt solutions. It is also used in some caustic environments. Inconel 600 Flange resists steam and mixtures of steam, air, and carbon dioxide.

The specified ASTM Standard Specification for Inconel 600 Flanges is ASTM B 564 with manufacturing standard such as ANSI/ASME B16.5, B16.47, BS4504, B 16.47 Series A & B, BS 10, EN-1092, DIN, etc. According to application and uses in pipes and tubes, Alloy 600 flanges are broadly grouped into different sort, for example, Welding Neck Flange(WNF) & Long Welding Neck Flange(LWNF), Slip-on Flange(SOF), Lap Joint Flange(LJW), Blind Flange, Socket Welding Flange (SWF), Threaded Flange(THW), Plate Flange. Inconel 600 Flange for the most part has different  face type, for example, Flat Face (FF), Raised Face (RF), Ring Type Joint (RTJ), blind flange, with various class rating as 50 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16,din 2.4856 , 25, 40 & ANSI B16.5. The specified ASTM Standard Specification for Inconel 600 pipe fittings is ASTM B 366, having Specific manufacturing Standards as ASME/ANSI B16.9, ASME B16.28, MSS-SP-43. Inconel 600 Fittings are categorically available are Elbow, Reducer, Tee, Coupling, Bend, Stub End, Cap, Nipple, Washer, Cross, Union etc. which are available in different  types such as Welded, Seamless and Fabricated having thickness range from 5s, 10s, 40s, 80s, 10, 20, 40, STD, 60, 80, XS, 100, 120, 140, 160, XXS available with NACE MR 01-75. The alloy’s strength and oxidation resistance at high temperatures make it useful for many applications in the heat-treating industry. 1:  In Pressure Vessel and Reactors  2:  Chemical processing, food processing and aerospace industries. 3:  In nuclear equipment, steam generators, super heaters and electronic parts. 4:  It is common in Gas turbine blades, seals, and combustors, Turbocharger rotors and seals. 5:  Inconel is increasingly used in the boilers of waste incinerators.  6:  Inconel alloy is also used in the automobile industry.
