Cupro Nickel Flanges Manufacturer & Supplier India

C-Flo Copper is a trusted Cupro Nickel flanges manufacturer and supplier in Mumbai, India. We offer top-tier solutions for sectors including marine engineering, offshore platforms, chemical processing, power plants, and heat exchangers. Our Cu-Ni flanges, made from 90/10 and 70/30 alloys, are highly resistant to corrosion, strong, and stable in temperature, which makes them an option for seawater use, desalination systems, and pipes in tough conditions.

Cupro Nickel is an alloy mainly composed of copper and nickel, with small amounts of iron and manganese to enhance strength and corrosion resistance. Marine piping systems and condensers widely use Cu-Ni 90/10 (90% copper, 10% nickel) due to its excellent resistance to biofouling and seawater corrosion. Cu-Ni 70/30 (70% copper, 30% nickel) provides enhanced strength and improved resistance to challenging marine environments, rendering it ideal for subsea pipelines and offshore oil rigs.

Cupro Nickel Flanges

We manufacture a wide range of copper nickel flanges, including weld neck, slip-on, socket weld, blind, threaded, lap joint, and spectacle blind flanges. These flanges comply with ASTM B151, ASTM B467, ASTM B171, and ASME B16.5 standards, guaranteeing precision, durability, and leak-proof connections. We offer a variety of sizes, including both standard and custom options, with diameters from ½” to 24” and pressure ratings spanning from 150 to 2500 classes.

Cupro Nickel flanges find extensive application in heat exchangers, shipbuilding, fire-fighting systems, and chemical processing plants, owing to their remarkable resistance to pitting, erosion, and extreme temperatures. Their ability to be welded and their mechanical strength render them appropriate for challenging industrial applications where exposure to saltwater, acids, and varying temperatures is common.

To provide protection against damage during shipment, C-Flo Copper uses hardwood boxes, moisture-resistant wrapping, and protective coatings as part of our commitment to safe and secure packaging. Local and international enterprises rely on our efficient and timely delivery services to meet urgent project deadlines. Being a top producer and supplier of copper-nickel flanges, we offer premium 90/10 copper flanges and 70/30 Cu Ni flanges at competitive costs.
