Engineered for Demanding Marine Applications

Copper Nickel 70 flanges are purpose-built for marine engineering, shipbuilding, and seawater piping, where durability and corrosion resistance are paramount. Designed using CuNi 70/30, these flanges excel in offshore and harsh saltwater environments. Their metallic bronze color and robust, round shape ensure both performance and aesthetic appeal in critical infrastructure projects.

Precision Manufacturing & Quality Assurance

Manufactured in India using advanced forging techniques, these flanges conform to major ANSI standards, with bolt hole diameters as per ANSI B16.5 or custom requirements. Each piece undergoes rigorous quality checks for hardness (90-110 HB), dimensional accuracy (0.5 mm), and surface finishing. The result is a reliable, high-strength connection for welded or bolted piping systems, packed securely for transport in wooden boxes or pallets.

FAQ's of Copper Nickel 70 Flange:

Q: How do Copper Nickel 70 flanges withstand harsh environments?

A: Copper Nickel 70 flanges, with a 70% copper and 30% nickel composition, offer superior corrosion resistance and structural integrity. Their material properties and high-strength forged construction allow them to perform effectively in demanding marine and offshore applications, resisting saltwater-induced corrosion and mechanical stress.

Q: What end types are available for Copper Nickel 70 flanges and how do I select the right one?

A: These flanges are available in Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) ends. The choice depends on your piping system's pressure rating and sealing requirements. RF and FF are commonly used for standard applications, while RTJ is ideal for higher-pressure scenarios needing metal-to-metal sealing.

Q: When should I specify custom bolt hole diameters for these flanges?

A: Custom bolt hole diameters are recommended when your piping system requires unique connection dimensions that do not align with standard ANSI B16.5 specifications. This ensures proper alignment, safety, and a secure fit for non-standard installations.

Q: Where are Copper Nickel 70 flanges typically used?

A: These flanges are widely utilized in marine engineering, shipbuilding, offshore structures, and seawater piping systems. Thanks to their corrosion resistance, they are suitable for environments exposed to saltwater and fluctuating temperatures up to 400C.

Q: What is the manufacturing process for these flanges?

A: Copper Nickel 70 flanges are produced using high-precision forging techniques in India. This process ensures superior mechanical strength, a smooth surface finish, and adherence to specified tolerances, making them dependable for demanding industrial applications.

Q: How are these flanges typically packed and shipped?

A: To ensure protection during transit, Copper Nickel 70 flanges are packaged in sturdy wooden boxes or pallets. This method minimizes risk of surface damage and maintains the high-quality finish until installation at the project site.

Q: What are the main benefits of using Copper Nickel 70 flanges in seawater applications?

A: The key advantages include excellent corrosion resistance, high mechanical strength, good weldability, and stable performance under a wide temperature range. These features make them a reliable choice for critical marine and industrial infrastructure.
