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:
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:

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.
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.

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.
