B16.5 F51 F53 F55 F60 F61 Duplex Weld Neck Flange

B16.5 F51 F53 F55 F60 F61 Duplex Weld Neck FlangeDuplex Steel of material includes grades 2205, F51, F53, and F60. Duplex stainless has increased in popularity over the years due to its excellent chemical and mechanical properties versus their basic stainless counterparts, given especially that the cost differences are minimal now as the availability has increased.The granular structure of duplex is a ferrite-austenite hybrid with a superior strength to weight ratio in comparison to 304 or 316. It balances the weldability of an austenitic with a pure ferritic and retains decent mechanical toughness in applications with exposure to colder ambient temperatures. Offshore/seawater applications are a common use for this type of steel due to its excellent stress corrosion cracking properties. Therefore, duplex is often found in desalination and pressure vessel equipment located in port cities.Duplex's premium mechanical and chemical properties are slightly offset by its difficulty in formability. These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.Specification :Duplex Steel FlangesDesign For Size:ANSI, EN, ASA, ASME, DIN, JIS, BS, PNFlange Machining Equipment:Bending machine, Pushing Machine, Sand-blasting machine, Press machine, electric bevelling machine etcConnect Type:LJF, RF, FF, LMF, SMF, RTJSize Chart :1/2″ (15 NB) To 48″ (1200NB)Production Process:Heat Treated, Machined, ForgedCoating Flanges Faces :Zinc Plated, Yellow Transparent, Anti-rust Paint, Cold and Hot Dip Galvanized, Oil Black PaintCommon Types of Flanges :Flanges 150 LB WNRFClass 300 RTJ600# BLRFClass 900 SORFSupporting Flanges Material:Gasket, Flanges Bolts, Ring JointApplication:Water Pipeline IndustryNatural Gas IndustryOil And Gas IndustryNuclear Power PlantChemical IndustryFabrication IndustryStandards:JIS Flanges, ISO Flanges, GOST Flanges, UNI Flanges, AWWA Flanges, MSS SP44 Flanges, ASME B16.5 Flanges, ASME B16.38 Flanges, EN-1092 Flanges, BS10 Flanges, DIN Flanges, PN Flanges, ASME B16.47 (Series A, Series B)Pressure Rating Table:Class 150 LBS, Class 300 LBS, Class 600 LBS, Class 900 LBS, Class 1500 LBS, Class 2500 LBSCompany ProfileFrom 1989 to now, Kingmetal Steel focus on manufacturing and distributing pipeline products including piping, fitting, flange, valve and fastener in stainless, carbon, alloy and duplex steel.
