High performance Cupro Nickel 70/30 Flanges that can function in extremely corrosive and high pressure environments are manufactured, stocked, and supplied by Sheetal Industries. With 70% copper and 30% nickel the copper-nickel alloy used to make these flanges has exceptional resistance to brine, seawater and other harsh media. This makes them ideal for marine, offshore, and chemical processing applications where strength, reliability, and corrosion resistance are critical.

Our Cupro Nickel 70/30 Flanges conform to international standards including ANSI, ASME, BS, DIN, and EN. They are composed of high-purity elements with copper (65.0% min), nickel (29–33%), manganese (up to 1%), iron (0.4–1.0%), zinc (1% max), and a trace of lead (0.05% max). These flanges provide exceptional mechanical strength with a tensile of 50,000 psi and a yield of 20,000 psi, providing durability in tough conditions. The elongation rate of the material at 30% and density of 0.323 lb/in³ offer high flexibility and heat resistance, making them perform well in both hot and cold conditions.
The flanges are widely used in oil and gas refineries, chemical plants, petrochemical plants, gas processing plants, power generation plants, food processing plants, fertilizer industries, and paper and pulp mills. They are particularly useful in marine cooling systems, condensers, heat exchangers, and seawater piping owing to their biofouling resistance and stress corrosion resistance. Precision machining, extensive testing, and quality checks are involved in our manufacturing process for providing consistent performance and dimensional accuracy.
We ensure that every Cupro Nickel 70/30 Flange is packed with maximum care to maintain its quality and integrity during shipping. Each flange is securely wrapped in protective materials and placed in sturdy, fumigated wooden boxes to avoid scratches, dents, or any form of damage while in transit. This careful packaging guarantees that the products reach our customers in perfect condition, ready for immediate use. We provide complete product documentation, including material test certificates (MTCs), third-party inspection reports, and quality assurance certificates. These documents confirm that every flange meets international standards and customer specifications.

Cutting and Shaping
Once the raw materials are selected, they undergo a precise cutting and shaping process.
Finishings and Coatings
Coating the materials to a specific temperature ensures they become malleable, facilitating the shaping process.
Welding and Joining
These processes ensure secure and leak-proof connections, enhancing the reliability and longevity.
Finishing and Quality Control
After this the buttweld fittings undergo comprehensive finishing and quality control procedures.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful packaging techniques.
