FAQ

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.
