What is Copper Nickel Flanges?
The copper nickel flanges are made of cupro-nickel material that shows high resistance to saltwater corrosion. They are also resistant to biofouling, pitting, crevice corrosion and stress corrosion cracking in the chloride environments. The material is able to retain its properties even at an elevated temperature. The copper nickel flanges have high ductility and they show good thermal conductivity, even in cryogenic temperatures. With the addition of nickel content to the alloys, the flow rates and strength of the flanges can be increased. Due to all these useful properties, the copper nickel flanges are widely used in different types of applications like marine, shipbuilding and repair, offshore oil drilling, power generation, etc. They are also used in different condensers and heat exchangers. Thus, the copper nickel flanges show great performance in both marine and non-marine environments.
There are different types of flanges available in the market, and each have their unique usage:

  • Weld neck flange- These are used in applications that involve severe and critical conditions.
  • Slip-on flange- They are suitable for low pressure applications.
  • Blind flange- They help to seal the ends of a piping system or pressure vessel opening.
  • Lap joint flange- These are a type of slip-on flange that comes with stub-end fittings. They are great for piping systems that need regular inspection and maintenance, as they can be disassembled easily.
  • Socket weld flange- These are used in small and high pressure pipes.
  • Threaded flange- They are used in pipes with threaded ends.
  • Orifice flange- They are used for accessing the line that helps to meter liquids or gases.
  • Ring-type joint flange- They are mostly used for high temperature and pressure applications. They help reduce the risk of leakages.
  • Reducing flange- These help in connecting one pipe to the other.
  • Forged flange- They help in creating pipework web for valves, pipes, and similar other devices.

Choosing the right type of flange is essential for proper execution of operations, as not all flanges are capable of withstanding all types of environments.

How can you Join Cupro Nickel Flange to Cuni Pipe?
A flange can be described as the way of joining pipes, valves, and other similar equipment, through welding or screwing. The copper nickel flanges are resistant to corrosion, and are also known for their high ductility. They also possess good fabricability and are biofouling resistant. Depending on the type of flange that is needed to be attached to the pipe, it is decided whether welding or screwing is needed to attach the flange with the pipe. For example, the slip-on flanges must be slid into the pipe before it is welded. This flange would also need double welding. On the other hand, the threaded flange does not need welding; it is joined by screwing the flanges to the pipe. It does not need any seam welding.

Copper Nickel 70/30 Flanges vs 90/10 Copper Nickel Flanges
The basic difference between the Copper Nickel 70/30 Flanges and the 90/10 Copper Nickel Flanges, is in its chemical composition. The 70/30 flanges consist of 70% copper and 30% nickel, with trace amounts of other elements. Similarly, the 90/10 flanges have 90% copper with 10% nickel, along with trace amounts of other elements. Due to this difference in the chemical composition, they have some difference in their physical properties too. The 70/30 CuNi flanges are resistant to seawater due to the manganese and iron elements present in it. The 90/10 CuNi flanges offer high strength corrosion resistance, with enhanced ductility and toughness. They are widely used in industrial and architectural applications.
The strength of 70/30 CuNi flanges are slightly more compared to the 90/10 CuNi flanges, and that is why the former is used for more demanding applications. The 90/10 CuNi can be described as a cost-effective substitute of 70/30 CuNi flanges. Both of them are superior in resisting corrosion, but 90/10 CuNi flanges offer a slightly better performance compared to the 70/30 CuNi flanges.

What should you Consider when Buying Copper Nickel Slip On Flanges?
The CuNi slip-on flanges are suitable for low pressure applications. They come with easy installation and can be welded into different pipes. It is essential to check the quality of the raw material and also the flanges should go through all the required tests before they are delivered for real-life applications. Primarily, these flanges are used in saltwater environments, heat exchangers, desalination plants, etc.

Are there Special Surface Finish for Copper Nickel Pipe Flanges?
There are several types of surface finishes available for CuNi flanges, like:

  • Stock Finish- here, the gasket formation takes place through a continuous spiral group. It is generated with the help of round-nose tools.
  • Smooth Finish- It comes without a visible tool marking; this surface finish looks very smooth.
  • Spiral serrated- It is quite similar to stock finish, except the fact that it comes with a “V” geometry.
  • Concentric Serrated- This one comes with concentric grooves, and there are even serration spaces present throughout the face.
  • Coldwater Finish- This one gives the flanges a finish that has a mirror-like appearance. This one is perfect to be used in metal to metal surface contacting, without the presence of any gasket.

Measuring Process Includes:

  • Using a level surface to place the cupronickel flange.
  • Choosing two bolt holes on the cupronickel flange that are opposite one other.
  • Measure the distance between the centers of one bolt hole and the center of the other bolt hole on your cupronickel flange with a tape measure.

Welding copper-nickel alloys flanges is simple. Welders of simple metallic structures do not need to pre-heat surfaces or apply any post-welding treatments because of the alloys. The sole criterion is that all surfaces that will be welded are free of impurities.

Cupronickel Slip-on VS Lap Joint Flange

They're very similar to one other, and they're common in applications that necessitate frequent disassembly for inspection. A lap joint copper nickel flange, on the other hand, is designed with a curved radius on the bore and face to accommodate the stub end of a lap joint.

The diameter of a circle that passes through each of the bolt holes is known as PCD (Pitch Circle Diameter). The Pitch Circle Diameter (PCD), which can indicate if the flange bolt holes will match, is one of the most significant metrics. From one side of the interior opening to the other, take a measurement across the center.

  • Copper Nickel Flange Type : Flanges are used for a variety of purposes, including connecting piping systems, redirecting, and dividing fluid flow.
  • Standard Specifications : should adhere to the appropriate quality performance standards
  • Material Grades : Copper Nickel 90-10 and Cuni 70-30 are two common material grades.
  • Size of the Flange: For a secure connection, the size of your cupronickel flange should match the size of your piping system.
  • Pressure and Temperature Rating : should be able to handle the pipe system's pressure and temperature

Manufacturing Process Of Copper Nickel Forged Flanges

ANSI is a US standard, while DIN is a European Union standard. ANSI or DIN certified flanges are available depending on the location.

Dimensions are measured in inches and pressure is measured in pounds per square inch (psi) according to ANSI standards. Dimensions for DIN, on the other hand, are measured in metric units with pressure in bars.
