Manufacture of ASTM B466 Cu-Ni 70/30 Welded And ERW Tubing for chemical, marine, oil and gas industry.

Copper Nickel 70/30 Pipe


Copper-Nickel, famously known as Cupronickel is an alloy that contains 60-90 % of copper. It is highly resistant to saltwater corrosion and thus Cupro Nickel 70/30 Pipes and Tubes are used in heat exchangers, condensers, and cryogenic applications due to good ductility retention and corrosion-resistant properties. Other benefits of Copper Nickel 70/30 Pipe  include sustaining high mechanical stress in high temperatures and find application in oil refinery and cement industries.

The petrochemical industry also uses Copper Nickel 70/30/ NES 780 because it provides resistance to biofouling and is readily weldable and fabricated. It has a tensile strength of 310 N/mm2 which makes it long-lasting. Copper-Nickel pipes also use industry-approved ASTM B466 Cupro Nickel 70/30 Seamless Pipe which has a low rate of expansion, extreme durability, and good heat conductibility. It has a Yield strength of 125 MPa and tensile strength up to 360 MPa.

Welded pipes such as Cu-ni 70/30 Welded pipe uses 70% copper and thus provides low-cost fabrication and high resistance to corrosion, thus finding application in propellers and military equipment. Hollow pipes like 70/30 Cu-ni Hollow pipe are used in high-pressure conditions such as bilge and ballast. Further, they have a unique cooling forming ability and thus beneficial for steam turbine condenser.

Industries are using standardized pipes such as Uns C71500 Square Pipe which has a high melting point of 1171 Celcius, a moderate density of 8.94 g/cm3, and tensile strength of up to 517 MPa. Other pipe having industry- standard corresponding to UNS is Werkstoff Nr 2.0882 Hexagonal Pipe is more dominant in marine engineering due to its corrosion-resistant feature.

Copper-Nickel pipes have found application in seawater cooling, sanitary, brine heaters, desalination plants, and offshore oil and gas platforms.
