Copper Nickel Pipes & Tubes Sub-Categories
Seawater-grade CuNi tubing for marine, offshore, heat exchangers and condenser systems — engineered for corrosion resistance and reliable service.
R V Metal Corporation supplies Copper Nickel (Cu-Ni) pipes and tubes in seamless and welded forms (as applicable by size and specification) for seawater cooling, shipbuilding, offshore platforms, desalination, condensers, heat exchangers and general marine engineering. Cu-Ni alloys are selected based on seawater velocity, temperature, erosion-corrosion risk, biofouling tendency, strength requirements, and fabrication needs (bending, flaring, expanding). CuNi 90/10 (UNS C70600) is widely used for seawater service with excellent corrosion resistance and workability. CuNi 70/30 (UNS C71500) offers higher strength and improved resistance in more demanding seawater conditions (higher velocities / higher erosion risk). Special Cu-Ni families (e.g., 95/5 or iron/manganese modified grades) are supplied as per customer standard and application requirements.
| Parameter | Specification |
|---|---|
| Grades (Common) |
CuNi 90/10 – UNS C70600 (seawater cooling, condensers, marine piping) CuNi 70/30 – UNS C71500 (higher strength; demanding seawater service) Also supplied: special Cu-Ni grades (e.g., 95/5 or modified Cu-Ni alloys) as per customer standard and service conditions. |
| Standards | ASTM / EN / IS supported (as applicable). Share your drawing/spec to lock chemistry, tolerances, temper and test plan. Typical ASTM families (as applicable): condenser/heat exchanger tubing and Cu-Ni pipe/tube standards. |
| Temper / Condition | Annealed (O) • Stress Relieved (SR) • As per ordered standard (availability depends on grade + size) |
| Size Range (OD) | As per order — round tubes and pipes supported. Provide OD/WT in inches (in) or millimetres (mm) and length in m/ft. |
| Units | All dimensions supported in mm and inches on drawings, MTC and packing lists |
| Testing (on request) | Dimensional checks • Eddy current (where required) • Hydro/pressure test (where specified) • Visual/surface checks • MTC |
