Cupro Nickel Pipes - Pumps, Valves, Piping and Fittings
Cupro-nickel pipes and fittings are corrosion-resistant copper-alloy components widely used in seawater systems aboard ships. Common marine grades are 90/10 Cu-Ni (UNS C70600) and 70/30 Cu-Ni (UNS C71500) for piping, pump connections, valves, condensers and heat exchangers.
ProShipWorks provides end-to-end support to source and supply Cupro Nickel Pipes for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common material and product standards include ASTM B466 and ASTM B467 for copper-nickel pipe, ASTM B111 for condenser and heat-exchanger tubes, and EN 12451 for copper and copper-alloy tubes. Exact certification depends on product form, dimensions and project specification. |
|---|---|
| Class Approval | Marine installations may require approval or material certification from DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, RINA or another vessel's classification society. Approval requirements depend on piping service, pressure, material grade, dimensions and applicable class rules. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify alloy grade, wall thickness, dimensions and pressure rating before installation. Use compatible Cu-Ni fittings and approved welding procedures. Keep pipe interiors clean, avoid carbon-steel contamination, provide proper supports, and control seawater flow velocity to limit erosion-corrosion. |
|---|---|
| Maintenance Tips | Inspect for leakage, dezincification-like attack, erosion, pitting, galvanic corrosion and mechanical damage. Keep strainers and seawater systems clean, monitor flow velocity and water chemistry, and replace components that exceed allowable wall-thickness loss. |
| Safety Notes | Depressurize, drain and isolate the system before cutting or dismantling. Use appropriate hot-work controls and ventilation during welding or brazing. Wear eye, hand and respiratory protection as required, and follow the vessel's permit-to-work and confined-space procedures. |
