Copper Nickel Forged Flanges , ASTM B151 / ASME SB151 / ASTM B152 / ASME SB152 Grade C71500 Cu-Ni 70/30
Yuhong Group has been operating austenitic stainless steel, nickel alloy steel (Hastelloy, Monel, Inconel, Incoloy), copper-nickel alloy products (pipes, fittings, flanges) for more than 25 years, with annual sales of steel pipes and pipes exceeding 50,000 tons, and also supply Millions of fittings and flanges. Our customers have covered more than 45 countries, such as Italy, the United Kingdom, Germany, the United States, Canada, Chile, Colombia, Saudi Arabia, South Korea, Singapore, Austria, Poland, France... and our group branches and factories have been Pass: ABS, DNV, GL, BV, PED 97/23/EC, AD2000-WO, GOST9941-81, CCS, TS, CNNC, ISO9001-2015, ISO 14001, ISO 18001,...
As a leading forged flange manufacturer in China, YUHONG offers ISO certified copper-nickel flanges, bulk storage of Cu-Ni 90/10 butt welding flanges, blind flanges and threaded flanges.
Copper-nickel consists mainly of copper and nickel, with small amounts of other elements. It has a beautiful yellow appearance due to the high copper content. The most popular copper nickels are UNS C70600 and C71500. UNS C70600 flanges are 90% copper and 10% nickel and are therefore also known as Cu-Ni 90/10 flanges. C71500 flanges are 70/30 copper nickel flanges.
We offer a full range of C70600 flanges including butt weld flanges, socket weld flanges, threaded flanges, blind flanges, slip flanges, lap flanges and eyeglass blinds.
Copper-nickel pipe flanges are widely used in seawater piping systems, crankshafts, light-duty condenser tubes, seawater pipeline desalination plants and offshore platforms.
The modulus of elasticity (C71500 annealed) of Cupro nickel flanges is 22000 ksi (152 GPa). Yield strength (annealed) of Cu-Ni WNRF flanges is 15000 psi (103 MPa). ASME SA151 Copper Nickel Threaded Flanges have a density of 0.323 lb/in³ (8.94 g/cm3). The Poisson's ratio of the copper-nickel threaded flange (C71500 annealed) is 0.325. These copper-nickel blind flange pressure ratings are very important because it determines which copper-nickel industrial flanges can be used, for which purpose, and in which industry. The copper-nickel grade forged flange is weldable, it shows oxidation resistance and very good corrosion. ANSI B16.5 Cuni Ring Fitting Flanges have excellent resistance to corrosion (especially sea water), cavitation and erosion. Cu-Ni RTJ flanges have good weldability. ASTM A151 Copper Nickel Threaded Flanges are durable and most importantly inexpensive. They are used in process equipment, hydraulic lines, automotive parts, underwater fencing, marine hardware components, feedwater heaters, pump components, heating cables and air conditioning equipment.
The pressure grades in the copper-nickel field are: 150 and 300 thicknesses: Sch5s, Sch10s, Sch40s, Sch80s. Material: ASTM B151 UNS C70600 / ASTM B151 UNS C71500
