Frequently Asked Questions

Copper Nickel flanges connect copper nickel pipes and tubes, valves, and pumps in seawater systems. They are common in shipbuilding, desalination plants, and offshore platforms for their biofouling and saltwater corrosion resistance.

We manufacture slip-on, weld neck, socket weld, blind, and threaded Copper Nickel flanges in grades 90/10 and 70/30, sized to match our copper nickel buttweld fittings and pipe range.

Yes. We produce custom Copper Nickel flanges from 1/2 inch to 24 inch, in pressure classes 150 to 900, alongside matching copper nickel socketweld fittings for the same piping system.

Share flange size, pressure class, facing type, grade (90/10 or 70/30), and quantity. Include the same details for any accompanying copper nickel threaded fittings so we can quote the full order together.

Each order comes with mill test certificates, chemical composition, and mechanical property reports. We also arrange third-party inspection from agencies such as Bureau Veritas or Lloyds when specified in the purchase order.

Copper nickel flanges are used to connect and seal piping components where corrosion resistance and reliable service are important. They are commonly selected for marine, seawater and industrial piping systems.

Common grades include Cu-Ni 90/10, identified as UNS C70600, and Cu-Ni 70/30, identified as UNS C71500. Availability should be confirmed against the required specification and project requirements.

Available configurations can include slip-on, weld neck, blind, socket weld, lap joint and orifice flanges. The exact type, size, face and pressure class should be specified when requesting a quotation.

Copper nickel flange pricing depends on factors such as material grade, flange type, size, pressure class, standard, quantity and required specifications. For an accurate price, provide the complete technical requirement to the supplier.

Provide the grade, flange type, nominal size, pressure class, applicable standard, face type and required quantity. If the flanges are for a specific project, sharing the drawing or technical specification can also help with quotation accuracy.
