70/30 copper nickel pipe manufacturer, established for 20 years +, providing you with excellent service and quality.
The giant 70/30 copper nickel pipe in our factory can be done to a maximum outside diameter of 219 and is seamless. The picture above shows our stock.
70/30 copper nickel pipe, also known as c7500pipe, has superior seawater corrosion resistance than c70600 pipe.
Because of corrosion and chemical resistance, CuNi70/30 tubes are used in seawater pipelines, chemical plants, heat exchangers and seawater pumps.

We have cuni 70/30 pipe in stock, lead time is one week if in stock. If not in stock the lead time is 45 days.
CuNi70/30 pipe is higher hardness than C70600 pipe, so the maximum outer diameter of CuNi70/30 seamless pipe can be 219mm. more than OD 219mm is welded pipe.
Copper nickel 70/30 pipes are resistant to seawater corrosion and are often used in heat exchangers in power plants, seawater cooling systems in shipbuilding, offshore petroleum projects, and seawater desalination.
Simply put, copper-nickel 70/30 tubing is composed of 70% copper and 30% nickel. Excellent resistance to seawater corrosion.
