Heat Exchangers
The C70600 and C71500 cupronickel tubes produced by Shanghai Hailiang are high-quality heat exchange copper tubes with excellent corrosion resistance and mechanical properties. They are widely used in ships, offshore engineering, petrochemicals, and other fields. These tubes can effectively resist corrosion from seawater, acidic solutions, and other corrosive media, ensuring the long-term stable operation of seawater desalination equipment. Since 2005, Hailiang has supplied tens of thousands of tons of cupronickel and aluminum brass tubes to major desalination companies such as Sidem (France), Doosan Heavy Industries (Korea), and Fisia (Italy).
