ASME SB111 C71500 SMLS 70-30 Copper-Nickel Alloy Steel Tube, Seawater Corrosion Resistance

ASME SB111 C71500 is a seamless 70-30 copper-nickel alloy tube renowned for its superior seawater corrosion resistance. The addition of nickel and iron enables the formation of a dense, stable protective surface film, effectively resisting pitting, impingement attack, and biofouling. Designed for harsh marine environments, it is the ideal choice for heat exchanger tubing in ship condensers, power plant cooling systems, and desalination plants.

2. Key Adventages

Superior Seawater Corrosion Resistance

Exhibits excellent resistance to corrosion in seawater and brackish water, effectively resisting pitting, crevice corrosion, and stress corrosion cracking.

Excellent Biofouling Resistance

The alloy surface inhibits the attachment and growth of marine organisms (such as barnacles, algae), reducing maintenance costs and maintaining heat exchange efficiency.

Good Mechanical and Fabrication Properties

Possesses high strength, good toughness, and ductility, making it easy for fabrication processes such as bending, welding, and forming.

Long Service Life

Capable of providing decades of reliable, trouble-free service life under correct operating conditions.

3. Key Applications

Shipbuilding & Marine Engineering: Ship condensers, heat exchangers, seawater cooling pipe systems.
Power Generation: Main condenser tubes and feedwater heater tubes for coastal and nuclear power plants.
Desalination Plants: Heat exchanger tubes and process piping in Multi-Stage Flash and Reverse Osmosis systems.
Offshore Oil & Gas: Subsea pipelines, platform cooling systems, firewater system piping.
