“TOBO-GROUP”, based in CHINA , has been created to promote and
distribute for the worldwide shipbuilding and offshore industries
copper nickel pipes, fittings & flanges, recognized as the best
compromise for seawater corrosion resistant line pipes material.
TOBO-GROUP offers:
Cupronickel (copper nickel) is an alloy of copper, nickel and
strengthening elements such as iron and manganese. Cupronickel
exhibits superior corrosion resistance in seawater. Because of
this, it is used for marine hardware, piping systems and sometimes
for the propellers, crankshafts and hulls of premium tugboats,
fishing boats and other working boats. The cupronickel alloy
technology has been known by the Chinese since the third century BC
under the name white copper and was used in corrosive environments.
It is still used extensively in modern boat building. It is
uniquely qualified as an ideal candidate for piping systems in the
ship-building industry due to its alloy properties, including low
general corrosion rates in seawater, resistance to stress corrosion
cracking due to ammonia in seawater, high resistance to crevice
corrosion and stress corrosion due to chlorides, good pitting
resistance, ready weldability, ease of fabrication and inherent
resistance to biofouling. In some cases, cupronickel seawater
piping systems can last a ship’s lifetime.
