Copper Nickel Flanges

Cu-Ni 90/10 or as referred to by 90% copper 10% nickel is an alloy grade that exhibits superior resistance to general corrosion like pitting in addition to marine water attacks. Flanges made from 90/10 Cuni have the ability to resist corrosion even when exposed to fast moving or high velocity water. This grade of Cupro Nickel 90/10 Weld Neck Flange has a nominal temperature coefficient of electric resistance. The high content of copper in the Copper Nickel 90/10 Flanges is what prevents stress related corrosion cracking along with pitting and crevice corrosion. Whereas the resistance of 90/10 Cuni BLRF Flange to soil erosion and abrasive fluids remains unparalleled in the aqueous conditions.

Hence, the 90/10 Cu/ni Alloy Flange is commonly employed in applications such as condenser tubes, seawater hardware and automotive cooling systems. What many manufacturers like about this copper-based flange that the alloy was developed as a cost-effective solution for the more expensive 70 30 Cu Ni alloy. The addition of approximately 1.4% iron and trace amounts of manganese in the alloy gives it good mechanical strength. While a blind flange is used to permanently seal off or shut off a valve or nozzle in a piping system, grade 90/10 Cupro Nickel Spectacle Flange is a safety device that is used by the worker to isolate a section of a line or a piece of equipment in times when the line or equipment is required to be inspected or removed from service.
