CARBON STEEL CS FLANGE

A carbon steel flange is a type of mechanical component used in piping systems to connect pipes, valves, pumps, and other equipment. They are typically made from carbon steel, which is known for its strength and durability. Here’s a detailed overview of standard specifications for carbon steel flanges:1. Standards and Specifications:• ASTM (American Society for Testing and Materials):o ASTM A105: Standard Specification for Carbon Steel Forgings for Piping Applications.o ASTM A350: Standard Specification for Carbon and Low-Alloy Steel Forgings for Pressure Vessels.o ASTM A516: Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service.• ANSI (American National Standards Institute):o ANSI B16.5: Specification for Pipe Flanges and Flanged Fittings, covering sizes from 1/2" to 24" in nominal pipe size and pressure classes ranging from 150 to 2500.o ANSI B16.36: is a standard developed by the American National Standards Institute (ANSI) that covers the specifications for metallic flanges and flanged fittings used in high-pressure, high-temperature applications.2. Types of Flanges:• Weld Neck Flange• Slip-On Flange• Blind Flange• Socket Weld Flange• Threaded Flange• Lap Joint Flange• Long Weld Neck Flange• Orifice Flange3. Pressure Classes:Carbon steel flanges are categorized into various pressure classes which denote their pressure-temperature ratings:• Class 150• Class 300• Class 600• Class 900• Class 1500• Class 2500Each class has a different pressure rating at various temperatures, which defines the flange's maximum working pressure.4. Materials and Finishes:• Material Grades: Typically, carbon steel flanges are made from grades like A105, A350 LF2, or A516.• Finish: Flanges might come with different surface finishes, including raised face, flat face, or ring-type joint.a. Raised Face (RF) Finishb. Flat Face (FF) Finishc. Ring Type Joint (RTJ) Finish5. Gaskets and Bolts:• Gaskets: Typically used with flanges to ensure a leak-proof seal. Common materials include graphite, metal, or PTFE.• Bolts: Flange connections are made using bolts and nuts, often specified according to the flange's pressure class.6. SPECFICATIONS:• Manufacturing Range: DN 15 (1/2”) to DN 1500 (60”)• Rating/Class: 150/300/600/900/1500/2500 & PN 10/16/25/40/63/100 etc.• Dimension Standard: ANSI/ASME B16.5/B16.47/B16.36/B16.48/DIN/EN 1092-1, etc.• Face Finish: Raised Face (RF) Finish, Flat Face (FF) Finish, Ring Type Joint (RTJ) Finish• Material Type: CARBON/ALLOY STEEL: ASTM/ASME A105/105N, ASTM / ASME A182, ASTM / ASME A335 GR F1, F5, F9, F11, F12, F22, F23, F91LTCS: ASTM/ASME A350 LF2, ASME/ASTM A694 F42, F46, F52, F60, F65, F70STAINLESS STEEL: ASTM A182 F304 (1.4301), F304L (1.4306/1.4307), F316 (1.4401), F316L (1.4404), F304H, F309S, F309H, F310S, F310H, F316TI, F316H, F316LN, F317, F317L, F321, F321H, F11, F22, F91, F347, F347H, F904L,  UNS S 31254 (1.4547) DUPLEX STEEL: Duplex (S32205 / S31803) X2CrNiMoN22-5-3 (1.4462), S32750 (EN/DIN 1.4410, X2CrNiMoN25-7-4), S32760 (1.4501, X2CrNiMoCuWN 25-7-4)HIGH NICKEL ALLOYS: Inconel 600, Inconel 625, Inconel 718, Inconel 800, Inconel 825, Monel 400, Monel K-500, Hastelloy C-276, Hastelloy B-2, Hastelloy C-22, Titanium Gr 2, Titanium Gr 5COPPER NICKEL ALLOYS: CUNI 90/10 (C70600), CUNI 70/30 (C71500)
