Product Description

C71500 Copper Nickel Seamless Tubing, Precision for Heat Exchanger

 

1.Product Introduction 

 

Copper nickel pipe is a high‑performance alloy tube manufactured from Cu‑Ni systems, primarily grades 90/10 (C70600) and 70/30 (C71500), with controlled additions of iron and manganese. Available in seamless and welded forms, it complies with ASTM B466, ASTM B111, ASME SB111, EN 12451 and JIS H3300. It is the preferred material for seawater and corrosive fluid handling.

 

2.Product Advantages

  • Outstanding resistance to seawater, brackish water, and brine corrosion.

  • Natural biofouling protection – copper ions inhibit marine organism attachment.

  • High resistance to erosion‑corrosion and impingement attack.

  • Excellent weldability, formability, and thermal conductivity.

  • Exceptional longevity – proven service life over 50 years in marine systems.

  • Immune to chloride stress‑corrosion cracking (SCC).

  • Lower weight than steel for equivalent pressure ratings.

  • More economical than titanium or high‑nickel alloys.

 

3.Product Applications

  • Shipbuilding & offshore – seawater cooling, ballast, fire‑fighting, and sanitary piping.

  • Oil & gas platforms – topside process lines, subsea umbilicals, and riser cladding.

  • Desalination – evaporator tubes and brine heaters.

  • Power generation – condenser tubes and cooling water circuits.

  • Industrial heat exchangers – chemical, petrochemical, and food processing.

  • Marine renewable energy – tidal/wave generator cooling systems.

  • Aquaculture – seawater supply and fish cage structures.

  • Automotive & aerospace – brake lines, power steering tubes, and aircraft ducting.
