All you need to Know About Copper Nickel 70/30 Pipes
Copper Nickel 70/30 Pipes
An alloy with 60 to 90% copper is known as cupronickel or copper-nickel. Cupro Nickel 70/30 Pipes and Pipes are utilised in heat exchangers, condensers, and cryogenic applications because of their excellent corrosion-resistant qualities and resistance to saltwater corrosion. The ability of Copper Nickel 70/30 Seamless Pipe to withstand high mechanical stress at high temperatures and find use in the cement and oil refining sectors are further advantages.
Copper-nickel (cupronickel) alloy UNS C71500 exhibits good creep resistance at high temperatures and medium-high strength. Compared to other alloys with comparable mechanical qualities and copper-aluminum alloys, this alloy is pricey.
Features of Copper Nickel 70/30 Pipe
There are two different kinds of copper-nickel alloys: 70/30 and 90/10. Due to the substantial levels of manganese and iron present, copper-nickel 70/30 is extremely resistant to corrosion caused by seawater.
A metal used in cryogenic applications is cupronickel. Its great ductility retention and thermal conductivity at very low temperatures make it the perfect material for heat exchangers in freezing facilities when utilised in cryogenic processing and storage equipment.
Despite having a high copper content, cupronickel exhibits a silvery chrome tint. Copper-nickel is utilised in seawater systems and maritime equipment such pipelines, heat exchangers, and condensers due to its exceptional corrosion resistance. High-quality hulls, shafts, and propellers are frequently constructed from this material. Other uses for this material include electrical, chemical, petrochemical, and military equipment.
Fabrication and Heat Treatment
The temperature range for annealing Cu-Ni 70/30 or UNS C71500 is between 649°C and 816°C (1200°F and 1500°F). The intermediate strength levels that 70/30 offers in the annealed condition make it a good material for use in more demanding applications. Additionally, copper-nickel alloys are easily fabricated and naturally resistant to biofouling.
Alloy 70/30 is easily hot- and cold-worked and responds well to practically all fabrication techniques. It can also be quickly linked using different welding techniques including brazing and soldering. With excellent hot and cold formability and malleability that is similar to that of copper 70/30, the material does not solidify instantaneously, causing it to draw and spin.
