Types of Copper Nickel Weld Neck Flanges
Weld neck copper nickel flanges in India are widely used in industries where reliable sealing is crucial, such as oil and gas, chemical processing, and marine applications. They are commonly used in low-pressure systems or when flange faces need to be connected directly. This type of flange provides a high-pressure and high-temperature sealing solution, commonly used in offshore, oil and gas, and petrochemical industries.
- Standard Weld Neck Flange: This is the most common type of weld neck flange, featuring a tapered neck and a hub that provides reinforcement and facilitates welding.
- Long Weld Neck Flange: Also known as a "long pattern" weld neck flange, this type has an extended neck, which provides additional strength and reduces the need for separate pipe sections or fittings.
- Compact Weld Neck Flange: This type of flange has a shorter neck length compared to the standard weld neck flange. It is used in compact piping systems or where space is limited.
- Counterbored Weld Neck Flange: In this type, the bore of the flange is enlarged to accommodate the outside diameter of the pipe.
- Weld Neck Flange with Special Facing: These flanges have special facing or surface treatments to meet specific requirements, such as anti-corrosion coatings or fire-resistant facings.
Features of Copper Nickel Weld Neck Flanges
- Weld neck flanges used in copper nickel applications are typically made from copper nickel alloys, such as Cu-Ni 90/10 (90% copper, 10% nickel) or Cu-Ni 70/30 (70% copper, 30% nickel).
- Weld neck flanges have a tapered neck that provides a smooth transition from the flange to the pipe.
- Weld neck flanges feature a hub or raised face around the bore of the flange.
- Weld neck flanges have bolt holes around the perimeter of the flange to secure it to the mating flange or equipment.
- Weld neck flanges are available in various pressure ratings to suit different piping system requirements.

Uses of Copper Nickel Weld Neck Flanges
Weld neck copper nickel flanges are extensively used in shipbuilding and offshore structures due to their excellent resistance to seawater corrosion. They are employed in piping systems for seawater cooling, firewater, ballast, and other essential services. Copper nickel alloys are highly resistant to corrosion in desalination plants, which convert seawater into freshwater. Weld neck copper nickel flanges are used in the piping systems of these plants to ensure reliable and long-lasting connections.
Quality of Copper Nickel Weld Neck Flange
High-quality weld neck copper nickel flanges are manufactured using precise and consistent copper nickel alloys, such as Cu-Ni 90/10 or Cu-Ni 70/30, which provide excellent corrosion resistance. The composition of the alloy should adhere to industry standards to ensure the desired properties and performance. A quality weld neck copper nickel flange exhibits superior corrosion resistance, particularly in marine and offshore environments.
