Product Description
ASTM B466 CuNi 70/30 Copper Nickel Welded Pipe High Strength Anti-Corrosion Tube
1.Product Description
Copper nickel pipe (Cu-Ni pipe) is a high‑performance alloy tube manufactured from copper‑nickel alloys, primarily grades 90/10 (UNS C70600) and 70/30 (UNS C71500), with small additions of iron and manganese. It is produced as seamless or welded pipe, conforming to ASTM B466, ASTM B111, ASME SB111, BS 2871, EN 12451, and JIS H3300. Renowned for its exceptional resistance to seawater corrosion and biofouling, it is the material of choice for marine, desalination, and heat‑exchange applications.
2.Product Functions
-
Efficient heat transfer in condensers, evaporators, and heat exchangers.
-
Reliable conveyance of seawater, fresh water, brine, oil, and industrial fluids.
-
Provides mechanical integrity and pressure resistance (Schedule 40/80 ratings).
-
Prevents marine growth on pipe surfaces through natural copper ion release.
-
Maintains good electrical conductivity where required.
3.Product Advantages
-
Exceptional resistance to seawater, brackish water, and erosion‑corrosion.
-
Natural anti‑biofouling – prevents barnacle and algae attachment.
-
High mechanical strength and ductility, service life up to 50 years.
-
Good weldability, formability, and thermal conductivity.
-
Immune to stress‑corrosion cracking and lightweight compared to steel.
