A copper nickel or cupro-nickel flange is a marine-grade item that has moderate strength and good thermal stability. The Cupro Nickel Flanges are utilized to connect pipes, tubes, and other equipment in the industry. These flanges are available commercially in 70/30 and 90/10 specifications. A Cuni Flange has excellent resistance to corrosion and pitting by acids in harsh environments. The flanges have good stability at oxidative levels and are tolerant against stress corrosion cracking. The Copper Nickel Pipe Flanges possess good fabricability and provide support to piping equipment as pressurized fluid and gases are passed through the line. These flanges showcase a density of 8.94 g/cm3 and possess outstanding mechanical properties. We are a Copper Nickel Flange manufacturer who uses the best raw materials and technology to produce quality-assured products.
Copper nickel flanges are designed in different configurations. A Copper Nickel Slip On Flange is very sought after in the industry as it is easy to install and is very cost-effective. These flanges are recommended in low-pressure and temperature applications. The Cuni Weld Neck Flange is recognized by a long hub that is seen in pressurized applications. These flanges are preferred in systems where repeated bending is taking place. Copper Nickel Backing Rings are used inside the butt-weld joint to prevent any metal from entering and contaminating the pipe. A Copper Nickel Blind Flange doesn’t possess a boring center. This allows the flanges to act as blanks to terminate the flow of media. Copper Nickel Threaded Flange doesn’t require any welding process to fit the pipe as it has threads that can be wound to subsequent grades. The Copper Nickel Composite Flange is designed with an inner copper flange and a carbon outer flange. These flanges are used in shipbuilding due to their versatile properties. Our institution is a Copper Nickel Flange supplier that has contact with different logistical supply chains, allowing us to transport products to you within a short time.
Sunflex Metal is a manufacturer and supplier of Copper Nickel Flange in India supply in grade of UNS C71500 & C70600. The Elongation at Break of Copper Nickel Flanges (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. Cupro Nickel Flanges has a Thermal Conductivity of 32.9 W/mK (0.0900 BTU in/hr.ft². °F) and it has a Rockwell B Hardness of 69. Cu-Ni Blind Flanges specifications detail the exact specifications of various kinds of Cuni Flanges products, for use in different types of applications. Copper Nickel Slip on Flanges has excellent hot and cold workability. ANSI B16.5 Cupro Nickel Orifice Flange can be obtained in various thickness and dimensions, as per the need.
Such types of Copper Nickel Pipe Flanges are used a lot in seawater piping systems, crankshafts, tubes for light-duty condensers, sea water pipe-work desalination units and in offshore platforms. Cupro Nickel Nippo Flanges has an Elastic Modulus (C71500 annealed) of 22000 ksi (152 GPa). The Yield Strength (annealed) of Cu-Ni WNRF Flanges is 15000 psi (103 MPa). ASME SA151 Copper Nickel Threaded Flange has a Density of 0.323 lb/in³ (8.94 g/cm3). The Poisson’s Ratio of Copper Nickel Screwed Flanges (C71500 annealed) is 0.325. These Copper Nickel Blind Flange pressure rating is very important as it determines what kind of Cu-Ni Industrial Flanges can be used, for which purpose, in which industry. Copper Nickel Grade Forged Flanges is solderable, it shows scaling resistance and very good corrosion. ANSI B16.5 Cuni Ring Type Joint Flanges exhibits superb resistance to corrosion (seawater especially), cavitation and erosion. Good weldability is displayed by Cu-Ni RTJ Flange. ASTM A151 Cu-Ni Threaded Flanges are durable and best of all, they are inexpensive. They are used in process equipment, hydraulic lines, automobile parts, underwater fencing, marine hardware components, feed water heaters, pump components, heating cables and in air conditioning plants.
