Description

COPPER NICKEL WELDING NECK FLANGE B151 C70600 / DIN 2.0872 RF TYPE

Copper nickel is mainly composed of copper and nickel, and contains small amounts of other elements. It has beautiful yellow appearance because of the large amount of copper. The most popular copper nickel are UNS C70600 and C71500. UNS C70600 Flanges contains 90% copper and 10% nickel, so it's also called Cu-Ni 90/10 flange. C71500 flange is 70/30 copper nickel flange.

The UNS C71500 is mainly used for military submarine services due to its higher strength, maximum allowable flow rate, and low magnetic permeability. However, due to the high cost of materials, this alloy has to some extent limited its wider commercial applications. Therefore, the 'main force' is UNS C70600 (CuNi 90/10, cupronickel). This alloy exhibits a well balanced combination of characteristics, allowing for its widespread and economical use.

ASME B16.5 C70600 flanges are mainly used on the oil field. There are 5 main flange types as below:

  1. Copper Nickel Weld Neck Flanges
  2. Copper Nickel Slip On Flanges
  3. Copper Nickel Socket Weld Flanges
  4. Copper Nickel Threaded Flanges
  5. Copper Nickel Blind Flanges

Advantages of UNS C70600 Flange:


ASTM B466 UNS C70600 Flange is stable and reliable at any temperature. It has good strength at moderate and elevate temperatures. At low temperatures, it maintains good mechanical properties, weld ability and high resistance to hydrogen. The great resistance to stress and erosion, excellent fabrication, high tensile strength, accurate dimensions make it largely used in seawater, aerospace, oil, chemical and gas industries.

Fabrication and Heat Treatment:

  • Annealing: UNS C70600 copper nickel alloys are annealed at temperatures between 593 and 816°C (1100 and 1500°F)
  • Cold Working: UNS C70600 copper nickel alloys have good cold working capacity.
  • Hot Working: Copper nickel 90/10 alloys have good hot forming capacity.
  • Welding: Copper nickel 90/10 alloys can be welded using gas shielded arc welding, spot welding, coated metal arc welding, butt welding, oxyacetylene welding, brazing, soldering and seam welding processes.
  • Forging: Temperatures between 843 and 954°C (1550 and 1750°F) are suitable for the forging of 90/10 copper nickel alloys.
  • Machinability: The machinability rating of copper nickel 90/10 alloys is 20%.

Applications:

  • Fire protection systems
  • Deluge systems
  • Sanitary plumbing services
  • Process cooling lines
  • Seawater piping
  • Splash zone sheathing
