Exceptional Corrosion Resistance

Designed for challenging marine and industrial applications, Cupro Nickel 90/10 flanges deliver outstanding resistance to seawater, salt, and various corrosive agents. This makes them a preferred choice in shipbuilding, oil & gas, desalination systems, and power plants where longevity and reliability are paramount.

Rigorous Quality Assurance

Each flange undergoes comprehensive quality testing, including ultrasonic, radiography, positive material identification (PMI), and hydrostatic testing. Flanges are clearly marked with grade, size, pressure, and heat number, and ship safely in wooden cases, pallets, or bundles with plastic wrapping to ensure integrity during transit.

Versatile Design and Applications

These flanges support a variety of face types-Raised Face, Flat Face, and Ring Type Joint-and connect via butt weld, socket weld, or threaded ends. They are ideal for both new installations and replacement projects due to their compatibility with global standards (ISO, ANSI, DIN, JIS, BS, EN) and sizes ranging from DN15 to DN600.

FAQ's of Cupro Nickel 90/10 Flanges (Sorf, Weldneck, Blind, Socketweld, Threaded):

Q: How are Cupro Nickel 90/10 flanges commonly used in marine and industrial applications?

A: Cupro Nickel 90/10 flanges are frequently used in marine engineering, shipbuilding, desalination plants, oil & gas sectors, heat exchangers, and power plants due to their excellent corrosion resistance and mechanical reliability in harsh environments.

Q: What are the benefits of using Cupro Nickel 90/10 flanges over other materials?

A: These flanges provide superior resistance to rust and seawater corrosion, possess high strength, are non-magnetic, and offer excellent weldability. Their smooth, machined finish and consistent quality make them ideal for critical and long-term installations.

Q: When should you choose a specific face type (RF, FF, RTJ) for these flanges?

A: The choice of Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ) depends on the assembly design and pressure requirements. RF is widely used for medium to high pressure, FF for low pressure and non-critical applications, and RTJ for high-pressure systems requiring leak-proof sealing.

Q: Where can you source Cupro Nickel 90/10 flanges in India?

A: Cupro Nickel 90/10 flanges are available through reputable manufacturers, exporters, importers, suppliers, traders, and wholesalers across India, all of whom typically comply with leading international standards such as ASTM, DIN, and BS.

Q: What is the manufacturing process for Cupro Nickel 90/10 flanges?

A: These flanges are produced by the forging process, followed by precise machining to achieve standard dimensions, smooth surfaces, and required finish. Rigorous quality checks and testing ensure each flange meets industry specifications and standards.

Q: How does the marking and packaging process ensure traceability and quality during delivery?

A: Each flange is marked with its grade, size, pressure rating, and heat number, ensuring traceability. Packaging in robust wooden cases, pallets, or bundles with plastic wrapping protects flanges from damage and corrosion during transportation.

Q: What quality tests are performed on each Cupro Nickel 90/10 flange before dispatch?

A: Every batch undergoes multiple quality checks, including ultrasonic testing, radiographic inspection, PMI for material verification, and hydrostatic pressure tests, ensuring consistent strength, safety, and compliance with industry norms.
