ASTM B111 C70600 Copper Nickle 90/10 Seamless Tube For Heat Exchanger Condenser

ASTM B111 C70600 Copper Nickle 90/10 Seamless Tube For Heat Exchanger and Condenser

ASTM B111 C70600 Copper Nickel 90/10 Seamless Tube is a type of tube material that is made from a copper-nickel alloy. This particular alloy consists of approximately 90% copper and 10% nickel, hence the designation "90/10." The ASTM B111 specification establishes the requirements for this type of seamless tube, which is commonly used in heat exchangers, condensers, and similar applications in marine environments where corrosion resistance is critical.

The addition of nickel to the copper improves the strength and corrosion resistance of the material, making it particularly suitable for use in saltwater environments. The 90/10 copper-nickel alloy is known for its durability, thermal stability, and excellent resistance to biofouling in seawater.

6.The Applications of YuHong ASTM B111 C70600 Copper Nickel 90/10 Seamless Tube

• Marine & Offshore Applications

a) Shipbuilding & Naval Systems

Condenser & Heat Exchanger Tubes – Used in marine condensers, evaporators, and coolers due to resistance to biofouling and seawater corrosion.

Seawater Piping Systems – Preferred for ballast water systems, firefighting lines, and desalination plants because it resists pitting and erosion.

Propulsion & Cooling Systems – Used in engine cooling, lubricating oil coolers, and exhaust gas scrubbers.

b) Offshore Oil & Gas

Platform Cooling Systems – Resists sulfide attack in sour gas environments.

Subsea Piping & Risers – Handles high-pressure seawater without degradation.

• Power Generation & Desalination

a) Power Plants (Nuclear, Thermal, & Coastal)

Feedwater Heaters & Condensers – Resists ammonia attack in steam systems.

Cooling Water Tubes – Used in coastal power stations where seawater cooling is required.

b) Desalination Plants

Multi-Stage Flash (MSF) & Reverse Osmosis (RO) Systems – Handles high-salinity brine without corrosion.

• Chemical & Process Industries

Heat Exchangers for Chemical Processing – Resists acidic and alkaline fluids.

Brine & Chloride Handling Systems – Used in chlor-alkali plants and saltwater refining.

• Industrial & HVAC Systems

Cooling Coils & Refrigeration Systems – Performs well in humid/salty environments (e.g., coastal HVAC systems).

Hydraulic & Instrumentation Tubing – Used in offshore rigs and chemical plants due to leak-proof reliability.

• Renewable Energy (Ocean Thermal & Offshore Wind)

Heat Exchangers for OTEC (Ocean Thermal Energy Conversion) – Withstands deep-sea water pressure & corrosion.

Cooling Systems for Offshore Wind Farms – Used in subsea transformer cooling.
