Copper Nickel Flanges

ASTM B151 Copper Nickel Pipe Flanges manufacturer In India, Check ANSI / ASME B16.5 Cu-Ni Weld Neck Flange Pressure Class And Dimensions Chart


Copper Nickel Flanges

Copper and nickel alloy is available in various compositions. These alloys are used to manufacturing various flanges. Copper Nickel Flanges have improved strength and durability. moreover, it also provides resistance to erosion and corrosion in natural water that includes brackish, and seawater. Copper Nickel Slip On Flanges is easy to install and weld and is suitable for low pressure applications. It is said to be ideal for saltwater and marine environments. ASTM B151 Copper Nickel Pipe Flanges manufacturer In India recommend the use of these flanges in desalination plants, naval shipping, hydraulic piping, fish farming cage, and in various other applications.

Copper Nickel Lap Joint Flange is used directly by sliding it over the pipe. It is used in applications that require to be dismantled frequently. On the other hand, a Cupro Nickel Blind Flange is used to block off the connection from one side either permanently or temporarily. It also offers superior corrosion to impingement. CNNI inner flange is hardened only by cold working and is used in securing diamond blades, grinding wheel, and a multi disc for different applications. CuNi Flanges when combined with carbon outer flange and copper nickel inner flange display a good ability to resist corrosion. 

Copper Nickel Flange have a long conical shaped head that goes over the wall of the pipe and is used in different applications as reinforcers. Cupro Nickel Plate Flange offers resistance to hydrogen embrittlement and good mechanical properties at sub zero and cryogenic temperature along with good weldability and fabricability. They also resist corrosion in aqueous environments. We at Fastwell can even customize the shape and size or even get the Copper Nickel Threaded Flange coated if required depending upon the specific requirement of the customer.
